How to Fix Heating & Air Conditioning Issues

Written by Chuck Kim on February 19, 2025. Posted in Air Conditioning, Blog, Furnaces, HVAC.

Your HVAC system is the foundation of keeping your home cool in the summer and toasty in the winter. A broken or malfunctioning system can leave you out in the cold, and you want answers fast. Some problems are easy to fix on your own, while more serious ones require professional help from an experienced HVAC technician.

If your AC or heater is not working, Semper Fi Heating & Cooling is here to help. We’ll go over common HVAC issues, how to fix your heating and air conditioning at home, and when it’s time to call in a professional HVAC company like us.

Common Reasons Your Heating or AC Is Not Working

Dealing with a malfunctioning HVAC system is frustrating, and the first step to solving it is determining the root problem. Once you know what’s going on, you can create a plan to fix it. Some of the most common causes for your HVAC not working properly include:

Power Issues

This may seem obvious, but your HVAC system needs power to run properly. The first step of troubleshooting your system is to check if it has adequate power. Something may have tripped the breaker in your home and cut power to the system, so look to check if this is the case. Also, take a look at your home’s fuse box and replace any blown fuses you find.

The other thing to check is the emergency shut-off switch. Make sure it’s in the “on” position and your HVAC system is getting adequate power.

Thermostat Issues

The thermostat is the brain of your heating and air conditioning, and it tells the system what to run and when to run it. Check that your thermostat is in the proper setting for what you need, whether that’s heating or cooling. You can also replace the batteries in the thermostat and make sure the wiring inside is secure and properly connected.

If your thermostat is in an area with a draft or direct sunlight, this can throw off the reading and cause your system to run inconsistently. Move it to an area away from direct sunlight near the center of your home to make sure the temperature reading is accurate.

Clogged or Dirty Air Filter

Your HVAC system requires proper airflow to keep it running smoothly and prevent it from overheating. It has air filters to catch dust and other debris before it travels throughout your home, and over time it can build up and cause a clog.

A dirty air filter reduces the efficiency of your system, but it’s an easy fix. Take a look at your filters and see if there’s a buildup of dust and other contaminants. If it looks full, you can purchase a new filter and install it yourself. Make sure you get the same size of filter and replace it every 1 to 3 months to keep your system running efficiently.

Low Refrigerant Levels

Your air conditioner uses refrigerant to cool the air before sending it through the vents across your home. If there isn’t enough refrigerant in the system, it can’t get the air as cold as it needs to be. Signs of low refrigerant levels to look out for include lukewarm air from the vents, a hissing sound, and ice buildup in your system.

Refrigerant recharges are a delicate process that requires professional help. It can be harmful if you come in direct contact with the material, and one wrong move could break your entire system. If you suspect the problem has to do with the refrigerant, call a professional HVAC company and let them handle it.

Frozen Evaporator Coil

Ice can build up on the evaporator coil in your air conditioner and prevent proper home cooling. If you notice a buildup of ice, turn off your AC and let it sit. Switch the fan to “on” to bring in some warm air, and gently use a hair dryer to melt the ice. Let the coils fully dry before you switch on the system again, and make sure your system has proper airflow and refrigerant levels.

Blocked or Dirty Condenser/Compressor Coils

Outdoor HVAC systems can get blocked up with dirt and foliage over time. You can keep your system running smoothly by clearing out any debris you see near your unit and making sure no dirt or leaves have snuck inside the unit.

Obstructed Airflow

Poor airflow reduces the efficiency of your system and prevents it from properly heating and cooling your home. Check that your vents and registers are clear of any debris or dust, and make sure the HVAC dampers are adjusted properly. Regular ductwork maintenance can also make sure everything looks good and your ducts are free of any dust or clogs.

Troubleshooting Guide: DIY Fixes Before Calling a Professional

Steps to Fix Your Air Conditioner

Check the Thermostat: Make sure your thermostat is set to the proper temperature and on the “cool” setting.
Inspect and Reset the Breaker or Fuse Box: Reset the breaker and check the fuse box to see if your AC is getting enough power.
Change or Clean the Air Filter: Take a look at the air filter in your unit and replace it if it looks full or clogged. Be sure to find the right size for your system.
Look for Ice on the AC Unit: Take a peak and see if you find any ice buildup inside your unit. Be sure to defrost it and melt the ice completely before turning the AC on again.
Clean the Outdoor Unit: If you have an outdoor unit, clear away any leaves, dirt, branches, or other debris that may be blocking air circulation.
Inspect Refrigerant Lines and Insulation: Check if there’s enough refrigerant in your unit and if it’s properly insulated.
Ensure Vents and Registers Are Open: Open the vents in your home and make sure the registers are clear of any blockages.

Steps to Fix Your Heater

Verify the Thermostat Settings: Make sure your thermostat is set to “heat” and the temperature setting is correct.
Check the Power Source and Reset the System: If both the breaker and fuse box in your home looks good, reset the heater to see if that starts it up.
Clean or Replace the Air Filter: Replace the air filter in your heater if it’s full of dust to improve airflow and unit efficiency.
Inspect the Heat Pump for Malfunctions: Check for any cracks or other visible problems that could lead to heater malfunctions.
Ensure the Gas Supply is On: If you have a gas furnace, make sure the gas supply is on and there’s adequate fuel getting to the unit.
Look for Pilot Light or Ignition Issues: The pilot light flame should be a vibrant blue; a red or yellow flame could indicate something is wrong. Make sure the ignition is working properly and your furnace is burning correctly.
Check for Frozen Outdoor Units: If you have an outdoor heat pump, see if parts are frozen and safely defrost them.

When To Reset Your HVAC System

Sometimes, a simple HVAC reset can kickstart your system into working like new. All you need to do is find the reset buttons on your unit and press them. Wait a few minutes before you start the system up again. If that doesn’t seem to work, you can try resetting the circuit breaker in your home to make sure your system is getting enough power. When resetting the unit or the breaker isn’t working, it may be time to contact a local HVAC professional.

Signs You Need Professional Help

You’ve tried all the troubleshooting tricks in the book, and none of them seem to work. Some issues are more complicated than a simple filter change, and in those moments you need professional HVAC help. You may need to call in the professionals if you notice:

Issues that persist after troubleshooting.
Loud noises or odors from your unit.
Signs of a refrigerant leak, such as hissing noises and ice formation.
Your system frequently turns on and off.
A sudden increase in your energy bills.

Preventative Maintenance Tips to Avoid Future Issues

No one wants to deal with a broken heater in the middle of winter, but you can help make sure that doesn’t happen. Regular HVAC upkeep can make sure your system is running smoothly and catch minor issues before they turn into serious breakdowns. To help prevent these issues from appearing in the first place, you can:

Replace your air filters every 1 to 3 months.
Schedule annual HVAC inspections and maintenance.
Keep your outdoor unit clear of any debris.
Check the calibration of your thermostat.
Schedule a professional air duct or vent cleaning.

Keep Your HVAC System Running Smoothly

Not all heating and cooling problems are created equal. Some simply require a filter change or system reset to keep your home cool in the summer. However, serious issues such as refrigerant leaks and loud banging from your system require a professional furnace and AC repairs to safely address the issue and get your home back up and running again.

Digital Thermostat Set To 78 Degrees - Best Temp for AC

The Best Temperature to Set Your AC at for Comfort & Savings

Written by Chuck Kim on February 19, 2025. Posted in Air Conditioning, Blog, HVAC.

When you come home from a long work day, you want your space to feel comfortable and cool to protect you from the summer heat. However, summers in the desert can get blazing hot, and your air conditioning must work overtime to maintain your desired room temperature. This can quickly skyrocket your monthly energy bill and reduce the longevity of your HVAC system.

The question homeowners in AZ and NV end up asking is, “How can I save money in the summer without sacrificing comfort?”

Your thermostat’s temperature settings may just be the answer.

At Semper Fi Heating & Cooling, we have years of experience working in the HVAC industry, and we know the ins and outs of air conditioning. We’ll go over some temperature recommendations for different times of day, other tips and tricks you can use to reduce your energy usage and debunk some common misconceptions about how to run your AC system.

What is the Best Temperature to Set Your AC?

You want your living space to feel comfortable without spending hundreds in utility costs. But is there an exact temperature that gives you the best of both worlds? There is!

The Department of Energy (DOE) recommends setting the thermostat to 78°F when you’re at home. Why this specific? They’ve found that this temperature is the perfect balance of personal comfort levels and improved energy efficiency. To put it simply, you save money while still being cool and comfortable on the couch.

While this is a great rule of thumb, there may be some personal adjustments you need to make so you remain comfortable in your home. Every home is different, and everyone’s comfort preferences are different, so you may need to adjust. However, keep in mind that setting a temperature cooler than 78 degrees will increase your monthly costs.

For example, people who live in an area with high humidity may want to run their system a little more to account for the stuffiness. If you’re an active person, you may want a cooler home when you come home sweating from a workout. For homes with more insulation, you may need to run your system less frequently to maintain a comfortable temperature.

Best AC Temperature for Sleeping

No one likes waking up sweaty in the middle of the night. Cooler temperatures when you sleep can improve the quality of your sleep and help you wake up feeling refreshed. The recommended thermostat setting for sleeping is anywhere between 60-67°F.

This is a stark contrast to the daytime temperature recommendation, with more than a 10-degree difference! Our bodies regulate our temperature differently while we sleep than while we’re awake. Many people run a little warmer when they sleep, and our internal temperature can vary depending on the sleep cycle stage. Keeping your bedroom a little cooler at night can help balance this extra heat, allowing you to fall asleep and stay asleep without waking up sweating.

If you’re worried about dropping the thermostat that low and overrunning your AC system, there are alternative things you can try to keep yourself cool. Utilize your ceiling fan to draw warm air up towards your ceiling and redistribute it around the room. You can also invest in a dehumidifier to reduce the moisture in your air and decrease that stuffy feeling. Lastly, invest in thin, breathable bedsheets that keep you comfortable without trapping your body heat.

Adjusting AC Temperature Based on Time of Day

Another great trick to help reduce the energy usage of your air conditioning during the summer is to make adjustments depending on the time of day and whether or not you’re home.

If you work in an office or travel enough to where you aren’t home during the day, you can increase the thermostat to around 85°F. It may be a little toasty, but you’re not there to feel it, and it reduces the amount of energy your HVAC system uses throughout the day. If you have pets who stay home all day, keep their safety and comfort in mind and adjust how much you increase the thermostat.

When you get home from work, you can reduce the temperature back down to around 78°F. When it’s time for bed, you can drop it further to keep your bedroom cool. You don’t want to immediately drop the thermostat from 85 to 65, as this will cause your AC to run continuously and burn a ton of energy to drastically drop your home’s temperature. Do it gradually throughout the evening to reduce the stress on your HVAC system.

It can be tough to remember to manually change your thermostat multiple times a day, and forgetting to adjust can cost you wasted energy. For peace of mind and improved efficiency, you can invest in a programmable or smart thermostat that makes the adjustments for you. You can program the thermostat to hold at a certain temperature at certain times of the day so you don’t have to worry about it.

How to Keep Your Home Cool Without Overworking the AC

When it gets especially hot outside, you want your home to be an oasis from the blazing sun. However, rising temperatures mean your air conditioning has to work harder to maintain the proper temperature in your home. This can strain the system and result in higher energy bills, but there are other things you can do. Here are some additional tips you can use to keep your home cool without running the air conditioning as much:

Utilize Air Circulation: Turn on your ceiling fan and invest in portable fans to keep air moving. Good air circulation prevents your home from getting stuffy and stale.
Use Window Treatments: The sun’s rays can heat your home even further. Close your blinds during peak sunlight hours to keep the heat out and your home cooler.
Seal Cracks & Improve Insulation: Sealing cracks and improving your home’s insulation keeps the heat out and traps the cold air in—that way your HVAC system doesn’t have to work as hard to maintain temperatures.
Be Aware of Heat-Generating Appliances: Reduce how often you use appliances that create heat such as the oven or dryer during peak hot hours in the middle of the day.

Energy-Saving Tips for Air Conditioning

Along with personal habits and thermostat adjustments, you can reduce your energy usage by taking care of your HVAC system. Ensuring your system isn’t working harder than it should saves you money and reduces the wear and tear on your system. Other energy-saving tips for your HVAC system include:

Set the thermostat fan to “Auto” instead of “On” to reduce how often the fans run.
Upgrade your home to a newer, more energy-efficient AC system with a good SEER rating.
Keep up with routine maintenance such as cleaning coils, replacing filters, and checking the refrigerant levels.
Create outdoor shade with landscaping and planting trees to reduce your home’s heat absorption.

Common AC Temperature Myths Debunked

There’s a lot of contradicting information on the internet about what the best temp to set the AC at is, and it can be tough to know what to believe. We’re here to debunk common AC myths so you can make an informed decision on what setting works best for your home:

Myth: Lowering the AC to 60°F Cools Your Home Faster

Some people argue that setting the thermostat to a lower temperature makes the system run faster and cools your home quicker. The reality is your HVAC system runs at the same rate no matter how low you set the thermostat; all it does is make your air conditioner run for longer and use more energy.

Myth: It’s Best to Turn Off the AC When You Leave the House

Another common argument is that since you’re not in the home, you should shut off your system entirely. However, this allows your home to skyrocket in temperature and get stuffy. When you get home, not only is your home going to be unbearably hot, but now your AC will have to work overtime to bring the temperature back down. It’s more energy-efficient to set the thermostat higher than it is to shut it off completely.

Myth: Fans Will Cool the Room

Box fans and standing fans don’t cool the air in your home. All they do is circulate the air and prevent it from getting stagnant and stuffy. The breeze cools us off, but it won’t change the overall temperature reading in your home.

Finding The Perfect Balance: Comfort, Efficiency, and Savings

Adjusting the thermostat throughout the day, investing in fans, and being aware of your energy usage can reduce your energy expenses without sacrificing your comfort. Finding the best temperature for air conditioning is a balancing act between personal comfort and energy savings. It can vary from person to person based on personal preference, so use trial and error to find what works best for your home.

Smart thermostats and regular AC maintenance can improve the energy efficiency of your home and save you money in the long run.

Why Is There Brown Water Coming From My Faucet and How To Fix It?

Written by Chuck Kim on February 12, 2025. Posted in Blog, Plumbing.

When you fill a pot from the faucet to cook your pasta for dinner, you expect to see clear water. Finding out your pasta water is brown from the faucet can leave you in a panic, and you may start to worry if something’s wrong with your plumbing. Luckily, brown water from the sink faucet is a relatively common problem for homeowners, and it’s solvable!

Are you frantically scrolling the internet trying to figure out why you have brown water coming out of the faucet? If so, you’ve come to the right page. Semper Fi Heating & Cooling has experience dealing with discolored tap water, and we’ll quickly go over common causes, how to fix the problem, and what you can do to prevent oddly-colored water in the future.

Common Causes of Brown Water

Rusted Pipes

As your plumbing system gets older, it can start to wear down and corrode. When your pipes start to rust, the rust can discolor your water as it travels through. Older homes that have galvanized steel pipes are at a greater risk of rust.

If you notice brown water from multiple fixtures throughout your home or after using a ton of water, rust could be the culprit. You’ll need a professional inspection to check for any corrosion.

Water Heater Issues

If your home uses a tanked water heater, sediments can start to build up in the water storage tank. Over time, this buildup causes corrosion and rust that can turn your water brown. While this is a similar issue to rusty pipes, rust in your heater results in brown tap water specifically when you turn on the hot water.

You can help prevent corrosion by regularly flushing your tank to remove sediments or replacing the anode rod in your heater.

Water Pressure Changes

Your plumbing system needs water pressure to push clean water throughout your home. If this pressure fluctuates, it can disturb the sediment in your water heater or nearby plumbing and turn your water brown. This can also happen if someone’s working on your main water line or using a nearby fire hydrant. The sediment that settles in your system can get stirred up and discolor your water.

External Contaminants

Factors outside of your control can also change the color of your water. Local weather conditions, such as heavy rainfall, can saturate the soil outside and cause it to seep into your plumbing system. This can discolor your water supply and make your water unpleasant to drink.

Nearby construction can also impact the cleanliness of your water supply. Heavy machinery kicks up a ton of dirt and other debris, which can leak into your plumbing system and turn your water brown.

Is Brown Water Harmful?

If you accidentally drank a glass of tap water or took a shower before you noticed the discoloration, there’s no need to panic. While brown water is unpleasant to look at, it’s not a serious risk to your health and safety. You may experience minor, short-term inconveniences such as stains on your clothes and mild skin irritation, but you’re not in any immediate danger.

If the discoloration is coming from rusty pipes or water heaters, the corrosion can breed germs that filter into your water and lead to extensive damage to your plumbing. Repairing corrosion quickly can clear up your water and prevent further issues.

Solutions to Fix Brown Water

Brown water from your faucet isn’t a lost cause. The most common causes are easily fixable and won’t cost you a fortune. Here’s what you can do to clear your water and get rid of any sediments or contaminants that turn it brown:

Immediate Actions

When you notice the brown discoloration in your water, the first thing you should do is turn on your cold water and let it run for around 20 minutes. This will clear out any sediment in your pipes. Try to avoid using any hot water so the contaminated water doesn’t filter into your water heater. If the water clears up after running it for a while, the cause is likely sediment buildup.

You can also check and see if your neighbors are experiencing a similar issue. If the entire neighborhood has brown water, then the problem could be with the main water line or outside forces like nearby construction.

Inspecting Pipes

Walk around your home and take a look at any exposed pipes you can easily access. Check for any signs of visible corrosion or rust that could discolor your water supply. Cracks and leaks can also let debris into your water, so look for those as well.

Consider contacting a professional plumber if you notice signs of corrosion. Replacing the pipe before the problem progresses can save you the headache of a plumbing emergency later down the road.

Flushing the Water Heater

Flushing your water heater once a year can prevent sediment buildup and corrosion in the tank. Turn off your heater and make sure it’s completely cooled to prevent a literal hot mess. From there, all you need to do is connect a hose to the drain valve, put the other end of the hose in your sink or outside, and let the water flow until the tank is empty.

A local plumber can also flush your heater for you if you don’t want to deal with the hassle. They can also do an annual checkup to make sure your heater is working properly and there are no signs of rust.

Contacting Authorities

In some cases, the problem may be outside of your home. If you notice discolored water coming from every fixture in your home and your neighbors are also dealing with the same thing, the problem may be in the main water line.

Your city is responsible for maintaining the main line and ensuring homeowners have access to clean water. Report any brown or discolored water to city officials if you suspect issues with the main water line.

Using Filtration Systems

Hard water and excess sediments can leave stains in your shower and residue in your hair, especially living in the Phoenix desert. Whole-home filtration systems and sediment filters can help reduce the contaminants in your water and keep it crystal clear. You can also look into water softening treatments that decrease the minerals in your water so you can enjoy a crisp glass of water fresh from the tap.

Preventative Measures for Clear Water

No one wants to turn on their faucet and be met with dirty, brown water. While issues can hide and turn your water gross overnight, you can help prevent it from ever happening in the first place. You can take preventative measures to make sure your water remains clear all year long, including:

Regular Plumbing Inspections

Sediment buildup and corrosion can be sneaky and hide away until it causes brown water or a leak. Annual inspections from a certified plumber can check for signs of corrosion and sediments and catch them early before they cause more problems. This not only saves your pasta water from turning brown, but you also save money on costly repairs and replacements later down the line.

Water Maintenance

Regular water heater upkeep can keep it running smoothly and prevent corrosion. Schedule regular system flushes with a plumber or do it yourself to keep the tank clear of any sediments. You can also keep an eye on the anode rod and replace it as needed.

Installing Modern Piping

To reduce the risk of rusty pipes, upgrade your system to copper or PEX pipes that are resistant to corrosion. These modern plumbing systems offer long-term reliability and peace of mind that your pipes are rust-free.

Water Treatment Options

If you live in an area with mineral-heavy water, sediment filters, and water-softening treatments can reduce the contaminants in your water and reduce the risk of corrosion and buildup. There are whole-home systems as well as filters that attach to your faucet.

Special Considerations for Local Water Systems

Certain factors can increase the risk of your water turning brown, some of which are out of your control. Older homes with aging infrastructure such as galvanized steel water pipes make the problem worse due to their high likelihood of rust and corrosion. Check to see what system your home uses and consider an upgrade if your plumbing is outdated.

Seasonal factors such as heavy rainfall and drought can also make your water look cloudy or dirty. If you notice sudden water discoloration, consider what the weather has been like recently and how that can affect your plumbing system.

When Should You Call Emergency Plumbing Services?

Written by Chuck Kim on February 12, 2025. Posted in Blog, Plumbing.

From a burst water pipe to a backed-up toilet, sudden plumbing problems can quickly flood your home and create more serious issues. If you find water in your home where it’s not supposed to be, your first thought is to call a plumber—but do you call the business number or an emergency plumber? What is a plumbing emergency?

If you’ve got your phone in your hand but aren’t sure whether to dial your regular plumber or an emergency service, Semper Fi Heating & Cooling can help. We’ll use our experience to provide some insight into what a plumbing emergency is, why it’s important to act fast, common plumbing emergencies, and what you can do while you wait for a plumber to arrive.

What is Considered a Plumbing Emergency?

Knowing whether to call a routine plumber or an emergency plumber can save you from hassle and unnecessary expenses in the long run. An emergency plumbing scenario is something that threatens the structural integrity and safety of your home and requires fast solutions to prevent further damage.

Pipe bursts, sewage backups, and gas leaks are all considered plumbing emergencies because they pose immediate dangers and must be repaired as soon as possible. On the other hand, routine issues such as a clogged drain or weak toilet flush don’t need immediate attention.

It’s important to note that many companies charge an additional emergency fee on top of the expenses to fix the issue. This fee covers the rapid response time as well as the service outside of regular business hours. No one wants to pay an unnecessary extra fee, so keep this in mind when debating whether to call an emergency line.

Why Acting Quickly Is Critical in Plumbing Emergencies

When water starts to flood your home, you need to act fast. Delays can worsen the damage to your home and lead to serious health and safety complications. The more the water damage spreads, the more it weakens the structural integrity of your home, leading to potential collapses. In addition, you and your loved ones could be exposed to harmful substances such as mold, sewage water, or gas leaks. Acting quickly can protect what’s important to you from further harm.

Not only is there a health and safety risk with waiting, but untreated plumbing emergencies can cost you financially. Addressing the problem quickly reduces water damage to your home and helps prevent costly repairs later down the line. The sooner you address the issue, the less it will cost you to fix it.

Common Plumbing Emergencies and How to Identify Them

Knowing what to look for in the event of a plumbing problem can help you prepare and know the proper service to call. If you’re not sure what constitutes a plumbing emergency, here are examples of the most common emergencies and what you can do to correctly identify them.

Burst Water Supply Pipes

Low water pressure, visible leaks, and loud noises inside your walls could all point toward a burst pipe in your home. Cracks and other damage to your pipes can cause water to seep out, and with enough pressure buildup, the pipe could burst open. In the event of a burst pipe, immediately shut off your home’s main water valve and contact an emergency plumber.

Sewage Backups

Sewage water backing up into your home is a serious health and environmental hazard that can lead to illness. Look for signs such as a foul odor in your home, water pooling outside your home, and water backup in your sinks or showers.

Water Heater Problems

A broken water heater can leave you out in the cold. Look for signs such as a lack of hot water in your home, odd noises from your unit, and visible leaks near your water heater.

If you have a gas water heater, a breakdown can lead to a dangerous gas leak in your home. If you suspect a gas leak, evacuate your home immediately and contact an emergency plumbing service.

Overflowing Toilets

Toilet clogs and malfunctioning float mechanisms can cause your toilet to overflow into your home. Before calling a plumber, try unclogging your toilet. If that doesn’t help, shut off the valve and get in touch with a plumber.

Gas Leaks

A gas leak is a serious emergency that requires immediate professional help. Watch for signs such as a rotten egg smell in your home, discolored stove flames, and a hissing noise. If you suspect a gas leak, immediately evacuate your home and contact emergency services. Open the windows and doors on your way out to let the gas dissipate without building up in your home.

Hidden Leaks and Their Long-Term Impact

Not all leaks leave obvious puddles in your home. Minor leaks can hide in your walls or ceilings and leave subtle hints like ceiling stains, mold growth, and sagging walls. These minor drips can quickly escalate into an emergency if left untreated as the water continues to spread.

What to Do in a Plumbing Emergency Before Help Arrives

When you call for plumbing services in an emergency, even the fastest team will take some time to arrive at your location. You don’t want to sit around doing nothing; take this time to try and minimize the damage. Here’s what you can do to protect your home while you wait for the plumber to arrive:

Turn Off Your Water and Gas: The first thing to do is shut off your home’s main water or gas line. This means you won’t have running water anywhere in your home, but it prevents more water or gas from leaking into your home and causing damage while you wait for help.
Protect Your Belongings: Move any personal valuables away from the leak and water damage to prevent them from getting soaked. For items you can’t move, cover them with a tarp or waterproof covering to prevent further damage.
Use Temporary Fixes: While you wait, the goal is damage control. Use buckets to collect any dripping water and find supports to hold up any weak areas of water damage.
Evacuate in an Emergency: In the event of a severe emergency, such as a gas leak or collapsed ceiling, evacuate your home immediately. Do what you can to keep yourself and your family safe while you wait for help.

How to Choose the Right Emergency Plumbing Service

In the event of a plumbing emergency, time is of the essence. However, you still need to take a minute and make sure you choose the right plumber for the job. You don’t want just anyone fixing your home—you need a reliable team who will fix the issue quickly.

Look for a local company in your area that has the proper certifications and 24/7 emergency services. A burst pipe doesn’t wait until regular business hours, and you need a plumber who’s available to help at any hour of the day.

Check customer reviews and see what they have to say about the company’s response time and the quality of their services. This will also give you an idea of how the company serves its customers.

Preventive Measures to Avoid Plumbing Emergencies

Don’t wait until a pipe bursts to take care of your plumbing system. Regular maintenance and check-ups can catch potential issues early before they lead to a serious emergency. A professional plumber should take a look at your system once a year to make sure everything looks good. You can also check your plumbing and maintain it with routine upkeep habits such as:

Inspect Your Pipes and Water Heater: Give your plumbing system a visual inspection and check for any signs of corrosion or cracks that could lead to leaks. Check that your water heater is working properly and everything looks good.
Clean Your Drains and Prevent Clogs: Use a drain snake or drain cleaner to clear out any minor clogs in your sink or shower drains. Clogs can prevent water flow and lead to water pooling, which over time can wear down your system and lead to water leaks.
Install Water Pressure Regulators: A common cause of a burst pipe or water leak is excess water pressure in your plumbing system. Installing a pressure regulator can make sure pressure doesn’t build up and lead to a serious problem.

Frequently Asked Questions

Is a small water leak an emergency?

It depends on where the leak is and what you can do to stop it while you wait for a plumber. A dripping shower head or sink is easy to contain, and you can avoid using those fixtures while you wait, so these aren’t considered emergencies. However, a leak that causes water damage to your walls or ceiling is an emergency, and you should call an emergency plumber as soon as possible.

How urgent is a leaky toilet?

A toilet leaking from the base could be dripping unsanitary water into your home, and this needs to be dealt with quickly. If the tank is leaking into the bowl, it’s not as big of an emergency, though it may cost you extra on your water bill. A plumber needs to fix these issues quickly.

Why won’t my toilet stop running?

A toilet that won’t stop running isn’t a plumbing emergency, but you could be wasting water. You can check the flapper and flush lever to make sure everything is working properly, and you can try DIY solutions before calling a plumber.

Protect Your Phoenix Home with Reliable Emergency Plumbing Services

In an emergency, acting fast can save your home and your wallet from serious damage. Not only do you protect what matters most to you, but you save money on more extensive repairs later on. Working with a reliable emergency plumber will keep your home water-free and ensure the issue is taken care of quickly.

How Long Do Heaters Last?

Not sure if it’s time to get a new heater (also known as a furnace)? Beyond purchasing well-made HVAC equipment, there are many factors that can shape the lifespan of a heater. Things like installation accuracy and frequency of heater maintenance can also impact how long your heating system provides reliable home comfort.

Let’s take a closer look at heater replacement and answer the question, “How long do heaters last?” We’ll start by reviewing the average heater duration and the factors that influence it. Next, we’ll list some of the key indicators that it’s time to replace your heating system, concluding with professional pointers for maximum heater longevity.

Let’s get started!

Average Heater Lifespan

Assuming it receives proper care and maintenance, a typical heater should provide dependable heating for 15 to 30 years. Regular upkeep—such as annual inspections, filter changes, and timely repairs—can significantly extend its operational life. While some rare units function beyond the 30-year mark, homeowners should realistically anticipate that their heater will perform within this general timeframe.

Many homeowners face the decision of whether to replace their heater before it fails. Some opt to proactively replace their unit once it is out of warranty, viewing this as a way to ensure continued efficiency and peace of mind. Others choose to invest in maintaining their existing heater, opting for service repairs until replacement becomes absolutely necessary.

Ultimately, the choice between preventive replacement and ongoing repairs often hinges on the heater’s condition, the cost of repairs, and individual comfort with the risk of unexpected failures.

Factors Affecting a Heater’s Lifespan

Your heating system should last you a couple of decades, but there are several key factors that will ultimately determine the lifespan of a heater:

Installation Quality: Proper installation is crucial for long-term performance. Poor ductwork design, improper sizing, or incorrectly sealed connections can restrict airflow and strain your system. When venting and fuel lines aren’t installed correctly, it can lead to inefficient operation and potentially reduce your heater’s lifespan by several years.

System Size: A heater that’s too large or too small for your home will cycle improperly, causing unnecessary wear on components. Oversized units short-cycle frequently, while undersized ones strain to meet heating demands. Either scenario can cut years off your system’s expected lifespan and drive up energy costs.

Maintenance Schedule: Annually scheduled furnace (heater) maintenance is vital for maximizing your heating system’s longevity. Regular cleaning, inspection, and tune-ups help identify minor issues before they become major problems. A well-maintained furnace can last 5-10 years longer than one that receives occasional care.

Usage Patterns: How you operate your heater significantly impacts its lifespan. Keeping thermostat settings between 60° and 80° Fahrenheit helps prevent system strain. Extreme temperature settings force your heater to work harder than necessary, potentially leading to premature component failure and shortened system life.

How Will I Know When to Replace My Heater?

Even well-maintained heaters eventually reach the end of their service life. When your heating system starts showing the following warning signs, it’s time to consider replacing it rather than investing in ongoing repairs. The silver lining? A new heater can provide improved comfort and energy savings compared to an aging unit.

Watch for these key indicators that it’s time to schedule a furnace (heater) replacement:

Rising Energy Bills: If your heating costs are climbing despite unchanged usage, your heater’s efficiency may be declining. Modern high-efficiency units can significantly reduce monthly energy expenses.

Frequent Repairs: When repair costs exceed 50% of the price for a new unit and service calls become frequent, replacing your heater is the more cost-effective choice.

Temperature Inconsistency: Uneven heating throughout your home or difficulty maintaining set temperatures often indicates your heater can no longer meet your heating demands effectively.

Unusual Noises: Rattles, bangs, or squeals may signal serious mechanical issues. While some noises warrant repair, multiple sound issues often indicate impending system failure.

Cold Air Output: A heater blowing cool air despite proper thermostat settings typically indicates major system problems that likely justify replacement.

How to Extend the Lifespan of Your Heater

Regular preventative heater maintenance is key to achieving the upper end of this lifespan. Trained HVAC professionals know how to identify potential issues before they lead to system failure, ensuring your heater stays dependable across multiple decades of service.

Here’s what you can do to protect your investment:

Professional Maintenance

Schedule annual professional maintenance with a qualified HVAC technician who knows how to thoroughly check, clean, and test components safely. Regular expert service helps catch minor issues before they become costly emergencies, ensuring your system operates at optimal efficiency.

DIY Maintenance

For routine maintenance between professional visits, check and replace your air filter monthly during peak heating season. Clean filters protect internal components from dust and debris while maintaining proper airflow.

Heat Pumps vs Furnaces: Which is Right for You?

Written by Chuck Kim on January 14, 2025. Posted in Blog, HVAC.

While traditional furnaces burn a fuel source to produce heat, heat pumps don’t. Instead, they use electricity and various refrigerants to transfer heat from one location to another. Specifically, they take heat from the outside and pump it into your home, which is why they’re called heat pumps.

These systems work similarly to your refrigerator. Your fridge uses refrigerant to absorb heat produced by the appliance and pushes it out to keep your food cold. The difference is that with a heat pump, you want that heat. The pump then takes in external heat and pushes it into your home.

Benefits of Heat Pumps

Improved Energy Efficiency

Heat pumps are overall more energy efficient than traditional furnaces. They use less electricity to move heat than a furnace burns fuel to create heat. This can save you money in the long run.

2 in 1

While they’re called heat pumps, these systems do the work of both a furnace and an air conditioning unit. Not only do you not have to worry about maintaining 2 separate units, but this also means it requires less energy for a heat pump to heat and cool your home.

Lower Maintenance Costs

Routine maintenance services for a heat pump are generally cheaper than maintenance for a furnace or air conditioning unit. After the initial installation, the cost to keep your system running smoothly is more affordable.

Benefits of Furnaces

A furnace (also known as a heater) is the typical heating system people think of when talking about home HVAC systems. These systems use either electricity or burning fuel to create heat that is then distributed throughout your home. While heat pumps move heat that’s already present, furnaces produce heat on their own.

Gas Furnaces

Gas furnaces can get warmer than a standard electric furnace. Since they burn fuel to produce heat, they can create more heat and warm your home more efficiently. These systems can burn either propane or natural gas.

Electric Furnaces

Electric furnaces heat metal coils to warm the air in the chamber before distributing it throughout your home. Since there’s no fuel to burn and therefore no combustion, there’s no risk of a gas leak or other serious complications.

Comparing Heat Pumps and Furnaces

When looking for a home heating solution, it’s important to know the pros and cons of each to make an informed decision. We’ll compare the cost, installation, efficiency, maintenance, and energy usage for both heat pumps and conventional heaters so you get a good idea of how each works. With this information, you’ll be able to come to an informed decision about which option is the right one for your home.

Cost

One of the first questions many people will ask when comparing heat pumps to furnaces is which is the cheaper option. Unfortunately, this isn’t a straightforward question to answer. The cost of a heat pump or furnace depends on factors such as where you live, what your home is currently equipped with, and how big your home is.

If your home doesn’t have a gas line and you want a furnace, it’ll cost more to install the proper line. In addition, larger homes require larger units to properly heat the space. Larger units are going to be more expensive. However, both heat pumps and furnaces qualify for tax incentives.

Installation

The installation process for each can vary based on the structure you already have in your home. If you already have the ductwork from an air conditioning unit, it’s a quick swap to put in a heat pump. However, without the ductwork, installation will include tearing through drywall and putting the proper vents and ducts throughout your home.

Similarly, gas furnace installations require a fuel line. If you don’t already have a gas line, one will need to be installed through your home and under your property. In the end, the installation process and cost fluctuate depending on your situation.

Efficiency

When discussing the efficiency of heat pumps and furnaces, it depends on where you live. Since heat pumps don’t produce their own heat and instead transfer heat from outside, their efficiency depends on the climate. If you live in an area with milder winters such as Phoenix, a heat pump is a great option that can keep up with colder winter nights.

In comparison, people who live in areas with snowy winters that get below freezing may want to consider a furnace. Heat pumps can struggle to pump heat into your home when temperatures get colder, and a furnace will always be able to burn fuel and produce heat.

Maintenance

Both furnaces and heat pumps require routine maintenance to keep them running properly. As mentioned earlier, heat pump maintenance appointments can be cheaper than furnace maintenance appointments. However, this is balanced by the fact that heat pumps require more frequent maintenance services than furnaces. So, while each appointment may be slightly cheaper, they happen more frequently.

In the long run, furnace (heater) maintenance tends to be more affordable than heat pump maintenance.

Energy Usage

Since heat pumps only transfer heat instead of producing it, they use noticeably less energy than a furnace. Furnaces have to create heat, which takes more energy and can cause an increase in your utility bills.

However, also keep in mind that a heat pump’s energy usage depends on the climate. In freezing temperatures, your pump will need more energy to properly heat your home, in which case a furnace may be the more energy-efficient option.

Which is Right for You?

After looking at the differences between heaters vs furnaces, how do you know which is the right one for your home? The short answer is: it depends. Furnaces produce more heat than heat pumps, but they can cost more to repair and maintain. There are pros and cons to both, and it’s important to weigh your options and choose the one that works best for you and your situation.

How to Winterize Your AC Unit

Written by Chuck Kim on January 13, 2025. Posted in HVAC, Maintenance.

As Phoenix and Las Vegas settle into their cooler months, many homeowners overlook a crucial task: winterizing their air conditioning units. While our desert winters are mild compared to other regions, leaving your AC system unprotected can lead to unexpected repairs and shortened equipment life. Even in our temperate climate, seasonal changes can expose your unit to damaging elements—from unexpected frost to corrosive dust storms.

At Semper Fi Heating & Cooling, we’ve seen firsthand how proper winter AC maintenance can extend your system’s lifespan and preserve efficiency. Taking simple precautions now can prevent costly repairs or downtime when summer returns.

In this guide, we’ll share our expert tips to winterize your AC unit so you can ensure it’s ready to perform when those triple-digit temperatures return.

Clean the AC Unit

Your air conditioner is vulnerable to the elements year-round, but cooler winter temperatures provide a convenient window for cleaning. To avoid electrical shock, start by turning off your AC (it’s getting less use anyway). Next, clear the unit by wiping away accumulated debris.

Look for and remove obstructions like:

Dirt
Dust
Leaves
Twigs and branches
Bug carcasses
Bird droppings

After the immediate vicinity has been cleaned and cleared, make sure to trim vegetation within a 2-foot perimeter of the AC unit. Doing so will allow for proper airflow once it’s time to power your AC unit back on.

Change the Air Filters

Your AC’s air filter is your home’s first line of defense against airborne contaminants that degrade performance and indoor air quality. As dust, pollen, and debris accumulate, your system is forced to work harder to maintain proper airflow. This additional strain not only elevates energy consumption but can also lead to mechanical wear and tear.

Winterize your AC unit by cleaning or replacing its air filters. The benefits of regular air filter replacement include:

Optimal system efficiency

A clean air filter provides better airflow, enabling your AC system to perform at peak capacity.

Reduced energy costs

When your AC operates efficiently, it consumes less power. By regularly replacing the air filter, you can potentially lower your utility bills and save money over time.

Reduced wear and tear

A clogged filter forces your cooling system to work overtime, which can lead to overheating and eventual failure. By changing the filters regularly, you help extend the lifespan of your HVAC equipment.

Improved indoor air quality

A clean air filter traps pollutants and allergens, providing you with healthier, breathable air. This is especially beneficial for individuals with allergies or respiratory issues, as it helps create a hygienic living environment.

Adjust the Thermostat

Cooler winter temperatures reduce our dependency on air conditioning. Use this to your advantage by adjusting your thermostat’s settings accordingly. When temperatures are nice outside during the winter, you can lower your air conditioner settings or turn off the system altogether. Adjusting your thermostat to reflect cooler outdoor temperatures not only reduces wear and tear but also reduces the amount of energy needed to cool your home.

Inspect the Ductwork

The air that’s cooled by your air conditioner is circulated through your home via a network of air ducts. As dust and debris accumulate in your ductwork over time, it can strain airflow, making it increasingly difficult to maintain HVAC efficiency.

Now is the perfect opportunity to have your ductwork professionally inspected for damage and cleared of the debris that’s built up during the cooling season. Consider scheduling an air duct cleaning appointment as part of your winter AC maintenance routine. During your appointment, air duct cleaning professionals will inspect for signs of air loss and make sure that areas with leaks are sealed for optimum performance.

Do a Test Run

Once you’ve taken the time to winterize your AC unit, make sure your due diligence has paid off with a test run. Start by turning your system back on and letting it run for 10-15 minutes. During this time, listen for abnormal sounds and observe your thermostat to make sure indoor air has reached the desired temperature.

If you notice anything out of the ordinary, call an HVAC professional immediately. They will send a trained technician over to double-check your work so that you can rest assured your AC runs smoothly when temperatures start to soar again.

Benefits of Proper HVAC Maintenance and Winterizations

Proper winter AC maintenance delivers substantial returns on your investment.

Some of the key benefits of HVAC maintenance include:

Lower Energy Bills: A well-maintained HVAC system operates at peak efficiency, consuming less power to maintain desired temperatures. Regular maintenance, including clean filters and properly sealed ducts, can reduce your energy consumption by up to 15%, leading to significant savings on monthly utility bills.

Extended System Lifespan: Just like any major appliance, your HVAC system needs regular care to perform at its full potential. With proper maintenance and winterization, your system can run reliably for 15 years or more, postponing the need for costly replacements.

Improved Air Quality: Regular maintenance helps your system filter out dust, allergens, and other airborne particles more effectively. Clean coils, fresh filters, and sanitized components ensure the air circulating through your home stays clean and healthy.

Prevention of Emergency Repairs: Routine AC and furnace maintenance helps identify and address potential issues before they escalate into major problems. This proactive approach not only saves you money but also prevents uncomfortable system failures during extreme temperatures.

Enhanced Home Comfort: A properly maintained HVAC system delivers consistent heating and cooling throughout your home. You’ll enjoy steady temperatures, reliable humidity control, and quieter operation year-round.

Furnace Not Blowing Hot Air? Here’s Why

Written by Chuck Kim on December 16, 2024. Posted in Air Conditioner Troubleshooting, Furnaces.

With winter just around the corner, keeping your home warm and cozy is a top priority as the temperatures drop. That’s what your furnace is for—just turn it on, and it should heat your home. At least, that’s the idea. But what if you turn on your furnace and discover it’s blowing cold air instead? That won’t do much to keep your family warm, and you’ll want answers fast to get things back on track.

Is your furnace or heater not blowing hot air? You’re in the right place. Here, we’ll walk you through 7 potential reasons your furnace might not be working properly—and when it’s time to call in the professionals.

Incorrect Thermostat Settings

If you notice your furnace is blowing cold air, the first thing you should do is check your thermostat. While this seems obvious, your furnace can blow cold air if the thermostat setting is wrong. You’ll want to check the fan setting as well. If your fan is set to “on,” then it will blow air continuously throughout your home, making the air feel cold. Try switching the fan setting to “auto” and see if that helps.

If this doesn’t fix the issue, check the temperature setting on your thermostat. It should be set to a temperature that’s higher than the current reading in your home. If it’s lower, make the necessary adjustments to reset the temperature.

After changing the fan and temperature settings, the last thing you can check is your thermostat’s batteries. Low or dead batteries can lead to improper temperature control, so change the batteries and see if that fixes the problem.

Dirty Filter

Do you remember the last time you changed the air filters on your furnace? If the most recent filter change was months or years ago, this may be the issue as to why your furnace isn’t blowing hot air.

HVAC air filters catch particles such as dust and allergens before they circulate throughout your home, making your air cleaner. Over time, these filters can get so full of dust and debris that airflow is limited in and around your furnace.

Luckily, this is an easy fix. Take out the filters in your furnace and hold them up to a light. You should be able to see some light passing through the filter. If you can’t see any light, this means the filter is full, and it’s time to replace it. Look at the size of the filter and make sure you replace it with the same size to ensure proper airflow.

You should change your air filter every 6 months. If you have pets or more traffic in your home, you may need to do it more frequently. Check your filters once a month to see if you need to replace them.

Pilot Light Issues

Gas furnaces use a pilot light to ignite the heater and warm the air. This light is meant to stay on at all times, but sometimes it can get blown out by accident. If you recently had maintenance done on your furnace, the pilot light may have been snuffed out. The first thing to do is check your furnace ignitor and see if the pilot light is on. If it’s off, you may be able to relight it yourself. Check your furnace’s manual to see how to safely relight it.

If you relight the pilot light and it goes out again shortly after, it could be dirty. A buildup of dust and other debris can prevent your pilot light from staying lit. You can clean off any debris you see and try relighting it again.

If the light goes out again after cleaning it, the last thing to check is the gas supply line. Make sure the line is open and your furnace is getting a consistent supply of gas.

Ducts are Leaking

The ducts in your home are what carry the warm air from your furnace to the vents throughout your home. Over time, these ducts can get worn down from daily use. This can lead to cracks or damage that cause outside air to mix with the warm air from your furnace. Cold air can seep in, and your warm air can leak out, leading to the air from your vents feeling cold.

Damage and weak spots in your ductwork can go unnoticed until you turn on your furnace and feel cold air. You can have an HVAC professional inspect your ducts and check for any damage or weak spots that can be letting in cold air.

Low Fuel Supply

Whether you have a gas, electric, or oil furnace, they all run off a fuel source to keep them running properly. Without fuel, your furnace may start to blow cold air without producing any heat.

Gas Furnace: A gas furnace can’t produce heat if it doesn’t have gas to burn. Check that your gas valve is open and your furnace is getting the gas it needs.
Electric Furnace: An electric furnace won’t run without power. If your furnace is not running at all, check for a blown fuse or breaker.
Oil Furnace: Oil furnaces need to burn oil to produce heat. Check to see if the oil tank is empty and if your furnace has enough fuel to run.

Old or Dirty Flame Sensors

Your furnace has a built-in flame sensor that turns it on and off depending on if there’s a flame present. This prevents gas from traveling through your vents and into your home. Over time, this sensor can become faulty and give false signals to the furnace. A buildup of dirt and grime can also cause the sensor to malfunction, leading to your furnace turning on and off repeatedly.

If the flame sensor shuts off your furnace, the fan may keep chugging along. This filters cold air throughout your home rather than the warm air you want.

Furnace Is Overheating

If your furnace is not blowing warm air, it could be that it’s overheating. Your furnace could be overheating for a variety of reasons, such as needing to replace your filters. As your furnace gets older, parts can begin to wear down and become less efficient.

If you suspect your furnace is overheating and you’ve tried the previous options with no success, contact an HVAC expert to take a look. The issue could be serious enough that you don’t want to risk trying to fix it yourself. Leave it to the professionals who know what they’re doing.

When Should You Call a Professional?

Your furnace and HVAC system consist of a ton of different parts that all work together to keep your home warm. When your furnace isn’t doing its job, there could be one of many causes. You can do basic at-home fixes such as replacing filters, adjusting the thermostat, and checking your furnace’s fuel source. Any other repairs need to be left to the professionals.

Semper Fi Heating & Cooling offers furnace repair services to get your home warm in time for winter. Our team will work with you to get to the root of the issue and get your furnace back up and running in no time. We also offer maintenance services to help prevent these issues from happening in the first place. We’re proud to serve our local communities in the Phoenix and Las Vegas areas.

The Benefits of Using a Smart Thermostat

Written by Chuck Kim on December 16, 2024. Posted in Blog, Indoor Air Quality, Reduce Utility Bills.

When the seasons begin to change, you may find yourself having to repeatedly adjust your thermostat to keep your home comfortable. Setting your thermostat to different temperatures throughout the day can reduce your energy bills each month and help you save money. However, it can get tedious to manually change the temperature with a traditional thermostat.

Luckily, as technology continues to advance, we’re seeing the HVAC industry growing with it. Smart thermostats allow you to set your temperature for different times of day and program a specific schedule—but that’s not all they offer.

If you want to learn more about this new HVAC technology, you’ve come to the right place. Semper Fi Heating & Cooling is here to guide you on how smart thermostats work and the top 10 benefits of using one in your home.

How Smart Thermostats Work

Smart thermostats use sensors to monitor the temperature in your home and trigger the heating or air conditioning to maintain your set temperature. You can also program your smart thermostat to maintain different temperatures at different times of day, and the thermostat will learn your routine and make adjustments on its own.

Most smart thermostats connect to your home’s WiFi and allow you to adjust the temperature from an app on your phone. With this convenient feature, you can turn on the air conditioner on your way home from work so your home is nice and cool when you return.

10 Reasons to Upgrade to a Smart Thermostat in Your Home

What sets a smart thermostat apart from a traditional one? Upgrading your thermostat is an investment, and you want to make sure that investment is worth it. We’re here to provide the information you need to make an informed decision. Here are 10 reasons you should use a smart thermostat in your home and upgrade today.

1. Reduce Your Energy Costs

With the cost of everything on the rise, you want to save money where you can. Smart thermostats use machine learning to learn your routine and make adjustments to your thermostat setting throughout the day. It’ll look at the temperature outside, your normal temperature settings, and how long it takes to heat or cool your home. With that information, it’ll adjust the thermostat as needed.

Over time, this clever technology can reduce your annual energy costs by up to 8%, which quickly adds up.

2. Thermostat Adjustments Tailored to Your Schedule

Whether you work a 9 to 5 job or have a more flexible schedule, you can program your smart thermostat to match your schedule. During the summer, you can program your thermostat to keep your home a little warmer while you’re at work and then have the air conditioning kick in when you get home. That way, you always come home to a cool and relaxing environment.

A smart thermostat can also use movement sensors to determine your daily activity patterns and adjust your thermostat temperature accordingly. You don’t have to lift a finger to keep your home comfortable.

3. Improve Indoor Air Quality

Your HVAC system can improve your indoor air quality as it circulates air. Filters in your system catch dust, pollen, and other debris before it travels throughout your home. A smart thermostat can send you alerts to change your filters when they get too full, helping to keep your indoor air clean and dust-free.

A smart thermostat also has humidity sensors that read the humidity levels in your home. It makes adjustments on its own to help prevent mold growth or excessive dryness in your home.

4. Increase Your HVAC System’s Lifespan

Your HVAC system is a significant investment of your time and money, and you want that investment to last as long as possible. A smart thermostat can make minor adjustments to your settings that lessen the wear and tear on your unit, helping it to last longer. The less your system has to work to keep your home comfortable, the longer its lifespan will be.

As mentioned earlier, smart thermostats also send you alerts for routine maintenance services such as filter changes. These minor maintenance practices make sure your system is working properly and can catch potential issues before they become more serious.

5. Balance Comfort and Energy Savings

Saving money on your energy bills doesn’t mean you have to bundle up in the winter while you watch television on the couch. A smart thermostat allows you to customize your temperature settings for maximum energy savings without having to sacrifice your comfort. The thermostat will learn your routine and adjust the temperature to your liking while you’re home.

When you’re at work or away from home, your smart thermostat will adjust the temperature so your HVAC system doesn’t run as often. When you come home, the thermostat will automatically shift the temperature to your personal preference so you stay nice and comfortable.

6. Get Updates & Alerts

A smart thermostat is not only convenient, but it’s also a helpful tool. We mentioned earlier that your smart thermostat can send you alerts for routine maintenance services such as filter replacements, but that’s not all it can do. You can get alerts straight to your phone about:

Sudden Power Outages
Your Energy Use Habits

7. Improve Your Home’s Resale Value

If you’re looking to sell your home, you may be looking into ways you can increase its value. A smart thermostat is an affordable investment that will make your home stand out on the market. Potential buyers will love the convenience and energy efficiency of a smart thermostat, which may make them more interested in your home.

8. Manage Your Settings on the Go

Smart thermostats connect to your home’s WiFi, so you can access your settings from the app on your phone or laptop. This means you can change the temperature in your home from anywhere. If you’re at work during the winter and want your home to be toasty when you get home, you can change the settings from your office before you start your commute home.

Whether you forgot to adjust the temperature before leaving for vacation or the weather takes an unexpected turn, you can just open the app and adjust your thermostat accordingly. This will save you money in the long run and prevent a massive energy bill when you get back from the beach.

9. Reduce Your Carbon Footprint

A smart thermostat is a great tool to help protect our planet! Since you use less energy, your home produces fewer emissions that could harm the environment. Not only do you save money, but you also save the environment. It’s a win-win!

10. Peace of Mind

No one wants to spend their time worrying about their HVAC system and whether their thermostat is working properly. As your thermostat gets older, the sensors can begin to fail, leading to increased energy use and an uncomfortable home. If your thermostat is getting older and starting to lose efficiency, it may be time for an upgrade.

With a smart thermostat, you get the peace of mind of a reliable system that will last for years. Many brands come with a warranty that ensures your new thermostat is protected in the event something happens.
