Types of Air Conditioning Repairs and Services

AC systems may need a range of services, from routine maintenance and tune-ups to complex repairs that restore efficiency and comfort. Here are some common service types:

AC repair: Fixes issues like poor cooling, leaks, or system breakdowns to restore normal operation
AC tune-up: Cleans, tests, and adjusts parts to keep the system efficient and reliable

Air quality and filtration improvements: Upgrades filters or duct systems to reduce dust and improve indoor air circulation
AC installation: Involves sizing, connecting, and setting up a new unit to ensure proper airflow and energy efficiency

Best Types of Air Conditioners for Arizona

Arizona’s hot climate demands cooling systems that work hard and deliver consistent comfort. Homeowners often rely on three main types of air conditioners, each designed to handle specific needs.

Split systems

A split system has two main parts: an outdoor compressor unit and an indoor air handler, connected by refrigerant lines. The indoor unit pulls in warm air, cools it through the evaporator coil, and pushes it back into the room, while the outdoor unit releases the absorbed heat outside.

Split systems work well for homes that need zoned cooling or areas without ductwork. They’re also useful for remodels or expansions where extending ducts isn’t practical. With quiet operation and efficient cooling, split systems give homeowners more flexibility to manage comfort in specific spaces.

Central air conditioning

Central AC uses a network of ducts to move cool air through the entire home. It’s the most common setup in Arizona because it delivers even cooling to every room, supports advanced thermostats, and handles larger square footage well. A properly installed central system also improves indoor air quality by filtering dust and allergens common in desert environments.

Room air conditioners

These units mount in windows or walls and focus on cooling a single room. They work well for apartments, small offices, or parts of the home that central AC doesn’t reach. Room air conditioners install quickly, cost less upfront, and allow homeowners to cool only the areas they use most, though they don’t match the power or efficiency of larger systems.

Key AC Features

Air conditioners now include features that improve efficiency, comfort, durability, and control. Here are some of the most important things to consider:

High SEER rating: The Seasonal Energy Efficiency Ratio (SEER) measures how efficiently a unit cools a space. A higher SEER rating means the system delivers more cooling with less electricity, which lowers monthly bills and improves overall performance.
Variable-speed compressors: These compressors adjust cooling output in small steps instead of switching only between on and off. This keeps temperatures steady, controls humidity better, reduces noise, and saves energy by running only as much as needed.
Corrosion resistance: Coils and components with corrosion-resistant coatings hold up better against moisture, dust, and Arizona’s harsh conditions. This protection keeps the system efficient for longer and reduces the risk of breakdowns.
Smart features: Wi-Fi connectivity, app controls, and smart thermostats let you adjust settings remotely, set schedules, and track energy use in real time. These tools improve comfort, reduce wasted electricity, and send alerts when maintenance is due.

Best AC Installers in Mesa, AZ FAQs

What are the best AC brands for Arizona?

The best AC brands for Arizona are those designed to perform well in long stretches of heat while keeping energy use in check. Systems need durability, high efficiency, and reliable parts that hold up against the desert climate.

Brands often recommended in Arizona include Bosch, Goodman, Johnson Controls, Rheem, Daikin, Gree, York, and Carrier. These manufacturers offer a range of central and ductless systems with high SEER ratings, corrosion-resistant materials, and advanced controls to match different home sizes and budgets.

Choosing the right brand comes down to your home’s needs and proper installation. Working with a trusted installer like Semper Fi ensures the system you select is set up correctly and built to deliver comfort year after year.

Should HVAC technicians be certified or licensed?

Yes, HVAC technicians should carry the right certifications and licensing before working on your system. In Arizona, licensing through the Registrar of Contractors ensures that they meet state standards for safety and performance.

Many professionals also hold EPA Section 608 certification to handle refrigerants legally, along with North American Technician Excellence (NATE) or similar technical certifications that prove advanced knowledge of heating and cooling systems. Companies like Semper Fi Heating & Cooling make certification a priority so every technician can diagnose, repair, and install systems according to industry and state requirements.

What is the $5,000 AC rule?

The $5,000 rule is a guideline that helps you decide if repairing or replacing your air conditioner makes more sense. To use it, multiply the repair cost by the system’s age. If the number is higher than $5,000, replacement is usually the smarter choice.

The rule works because it compares the money you would sink into repairs with the value of investing in a new system. A high total signals that your AC is near the end of its life and that repair costs will likely keep stacking up. Replacing the unit at that point often saves money in the long run and gives you a system that’s more reliable and energy efficient.

How much does a new AC unit cost in AZ?

In Arizona, most homeowners spend between $6,000 and $12,000 for a full AC replacement. Smaller units or simpler installs can run closer to $3,000–$7,000, while larger homes or high-efficiency models land on the higher end. The exact price depends on things like the size of your home, the type of system you choose, ductwork, and labor. The best way to get an accurate number is to ask a licensed installer for a detailed quote.

Why Your AC Won’t Start, Stop, or Shut Off (and What You Can Actually Do About It)

Written by Hector Waldo on May 9, 2025. Posted in Air Conditioner Troubleshooting, Air Conditioner Tune-Up, Air Conditioning, Air Conditioning Repair, Air Conditioning Replacement, HVAC, Maintenance.

Why Your AC Won’t Start, Stop, or Shut Off (and What You Can Actually Do About It)

Let’s be honest—AC issues always seem to hit at the worst possible time. Whether it won’t turn on, won’t stop running, or is working non-stop without cooling, it’s a headache you don’t have time for. But don’t sweat it (literally)—we’ve got the rundown of what might be wrong and how you can fix it yourself before calling in the pros.

So, Your AC Won’t Start?

If your AC isn’t starting, consider the following potential causes:

Thermostat Settings: Make sure it’s set to “cool”, and your desired temperature is set below the current room temperature. It’s simple but often overlooked.
Power Issues: Flip your breaker panel and check for anything tripped. A quick reset might do the trick. It could be as simple as that!
Clogged Air Filter: A dirty filter can constrict the airflow and trigger safety shutoffs. Try swapping it out and see if that solves the problem.
Emergency Shut-Off Switches: Look around the indoor and outdoor units—sometimes there’s a manual switch that’s been flipped off without you realizing it.
Blocked Drain Line: If the pan is full or the line is clogged, it might shut down for safety. Clear it out and you’re good to go.
Faulty capacitors or contactors: These store energy to start-up your system. If they’re failing, your AC may not start. You’ll need diagnosis and replacement from a pro.
Professional assessment: If you’re hearing weird sounds or nothing’s happening at all, the compressor could be dead. Time to get someone out to take a look.

Your AC Won’t Turn Off

If your system is running a marathon and refuses to quit, here’s what might be happening:

Thermostat Malfunction: If it’s misreading the temp or is outdated, it might not know when to shut off. Check to see if it’s functioning correctly.
Dirty Outdoor Coils: The coils help release heat. When they become gunky, your AC has to work overtime. Regularly clean them to help your system chill out.
Low Refrigerant: When there’s a leak, your AC can’t reach the set temp and just keeps running. If you suspect a leak, call in a professional tech.
Fan Limit Switch Issues: This switch controls your blower fan. If it’s stuck in the “on” position, the fan won’t stop. Get it checked by a professional.

It’s Running… But Your House Is Still Hot

This might be the most frustrating problem: your AC is running constantly, but you’re still sweating. Here’s what could be going on:

Wrong- Sized Unit: Too small and it never catches up. Too big and it cycles on and off too fast. You might need a new unit installation.
Leaky Ducts: Cooled air might be escaping through holes in the ductwork. If so, get them checked and have them sealed
Closed Vents or Blockages: Walk around and make sure none of your vents are closed or blocked.
Older System: If it’s more than 10–15 years old, it might just be worn out. You may want to consider a replacement.

Keep It Running Smoothly With These Quick Maintenance Tips

Change Filters: Every 1–3 months. Seriously, it makes a big difference.
Tune-Ups: Book a pro to tune up your system once or twice a year.
Clean the Outdoor Unit: Keep leaves, dirt, and debris away as much as possible. Gently hose off the condenser coils too.
Use Your Thermostat Wisely: A smart thermostat can optimize cooling schedules and save you money over time.

Still No Luck?

We are here to help with all your HVAC needs, and in the event you need an emergency plumbing contractor in Phoenix, AZ, we’ve got trusted partners who can handle your plumbing emergencies swiftly and professionally.

Why Your AC Needs a Surge Protector: Protect Your Comfort and Your Wallet

Written by Hector Waldo on May 9, 2025. Posted in Air Conditioner Troubleshooting, Air Conditioning, Blog, HVAC, Maintenance.

When you hear “surge protector,” you probably think of that power strip under your desk with your laptop, phone charger, and TV plugged into it. But here’s something most homeowners don’t realize—your air conditioner needs protection too.

Power surges don’t give you a heads-up. They can hit suddenly and do some serious damage, especially to big-ticket items like your HVAC system. That’s why at Semper Fi Heating and Cooling, we’re big fans of playing it smart and staying protected.

An AC surge protector is like a bodyguard for your system. It helps shield your air conditioner from unexpected voltage spikes, keeping it safe, running smoothly, and saving you from surprise repair bills. In the next section, we’ll break down exactly what an AC surge protector does and why it’s one of the smartest upgrades you can make for your home.

What Is an AC Surge Protector, Exactly?

Think of a surge protector as a shield for your electrical equipment. Most people are used to the kind you plug your TV or computer into—but your HVAC system needs something with a little more muscle.

An AC surge protector is a more powerful version, installed right at your main electrical panel or outdoor AC unit. Its job? Spot voltage spikes—whether they come from lightning, power grid issues, or something inside your home—and safely redirect that extra electricity away from your HVAC system.

It’s a simple device that does a big job: protecting your air conditioner from damage and keeping your home comfortable and safe.

How Does an AC Surge Protector Work?

Inside every surge protector are components like metal oxide varistors (MOVs) and sometimes gas discharge arresters (GDAs). You don’t need to remember those names—but here’s what they do:

Absorb and safely redirect excess voltage before it hits your system
React in nanoseconds to keep delicate parts from frying
Protect critical components like your compressor, circuit board, and fan motors

In short: when a surge hits, the protector takes the blow—not your AC. It’s like armor for one of the most important systems in your home.

Why You Might Want an HVAC Surge Protector

Power surges aren’t just rare events caused by lightning—they can come from the power grid, large appliances cycling on and off, or even wiring issues. And those little spikes? Over time, they add up. Here’s why adding a surge protector to your HVAC system is a smart move:

Protect Your Investment: Your AC system isn’t cheap. One major surge can fry crucial parts like the compressor or control board—and that repair bill can get real pricey. A surge protector acts as a shield to help prevent that damage.
Avoid Costly Repairs: Think of a surge protector as insurance. It helps you dodge those unexpected repair costs that can pop up after a storm or random voltage spike.
Prevent System Downtime: When your AC is out, especially during an Arizona summer, it’s not just uncomfortable—it’s unbearable. A surge protector helps keep your system online and your home cool.
Extend the Life of Your AC: Every surge, big or small, puts stress on your system. Over time, that wear and tear shortens its life. Surge protection helps keep everything running smoothly, longer.
Keep Your Home Safer: Electrical surges can sometimes lead to sparks or fires. By protecting your HVAC system, you’re also helping to protect your home and your loved ones.

What to Look for in an AC Surge Protector

Not all surge protectors are created equal. If you’re shopping for one to protect your HVAC system, here are a few key features to keep in mind:

Joule Rating: This tells you how much energy the device can absorb before it fails. Aim for at least 600 to 1000+ joules for solid protection.
Clamping Voltage: This is the voltage level at which the surge protector kicks in. The lower, the better—look for something 400 volts or less to catch spikes early.
Response Time: Surges happen fast, so your protection should be faster. Choose a model that reacts in nanoseconds or less to stay ahead of any damage. Of course, you don’t have to figure this all out alone. A licensed technician (like our team at Semper Fi!) can recommend the right surge protector based on your system and your home’s electrical needs.

Professional Installation Matters

Surge protection for your HVAC system isn’t something you want to DIY. It means working with high-voltage components like your electrical panel or outdoor AC unit—and that’s a job best left to the pros.

At Semper Fi Heating & Cooling, our certified ductless mini split installation technicians in Phoenix, AZ, are trained to install surge protectors safely and correctly. We’ll make sure your system is protected the right way, giving you peace of mind and long-term protection, just like our thermostat installation contractors in Phoenix, AZ, who ensure every home stays comfortable and efficient year-round.

FAQs About AC Surge Protection

Q: Do I really need surge protection for my AC? A: Absolutely. Your HVAC system is full of sensitive electronics—like control boards and compressors—that don’t handle power spikes well. A surge protector is a simple, cost-effective way to protect one of your home’s biggest investments.

Q: Doesn’t my circuit breaker already protect my system? A: Not exactly. Circuit breakers guard against overloads and short circuits—not sudden voltage spikes. Surge protectors are specifically designed to stop those surges in their tracks.

Q: How long does an HVAC surge protector last? A: Most last anywhere from 2 to 5 years, depending on how often they take a hit. Regular inspections will help make sure you’re always protected.

Q: Can a surge protector prevent lightning damage? A: While nothing can fully protect against a direct lightning strike, a quality whole-home surge protector can dramatically reduce the risk and impact of nearby strikes or grid disturbances.

At Semper Fi Heating and Cooling, we’re here to help you stay protected, comfortable, and worry-free. Call 480-616-3636 today to ask about surge protector options for your HVAC system and remember, if you ever need emergency plumbing services in Phoenix, AZ, we’re here to help with that too!

How to Fix Heating & Air Conditioning Issues

Written by Hector Waldo 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, contact a professional HVAC contractor in Buckeye, Peoria and Phoenix to handle it safely and correctly.

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 Hector Waldo 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.

Should You Turn Off Your AC When On Vacation?

Written by Hector Waldo on October 10, 2024. Posted in Air Conditioning, Blog.

One of life’s biggest dilemmas: should you turn the AC off when going on vacation? If no one is going to be in the house, does it need to be cool? Whether it be a weekend trip to a bed and breakfast or a month-long family vacation, many homeowners grapple with the decision to either leave the air conditioning on while they are gone or turn it off to try and save energy.

Before making such a choice, it’s important to weigh the pros and cons and make an informed decision. This article will go over points to consider when deciding whether to turn up the thermostat while you are away, as well as other things you can do to help lower your energy bill each month.

Is It Bad to Turn Off My AC While on Vacation?

While it may seem like a good idea at first, turning off your AC when you leave for vacation can cause more harm than good. Having no air circulation in your home for extended periods can cause humidity to build up in your home and cause problems throughout.

If it’s really hot where you live, like the Arizona desert, temperatures in the summer can reach over 100 degrees Fahrenheit. Letting the inside of your home reach those temperatures can begin to cause problems with your personal belongings and the structure of your home.

If you are going to be gone for a brief period of a couple of days, then it is best to leave your AC at the same temperature you normally leave it at. If you are going to be gone for longer than a few days, you can set your thermostat to around 85 degrees so it will still run and circulate air, just not as frequently.

The Cons of Turning Off Your AC Before Vacation

Increased Humidity in Your Home: Without air circulation in your home, humidity can start to build up and lead to potential problems. An increase in moisture can cause problems such as mold and mildew growth on your furniture, walls, and even your personal belongings.
Pest Infestations: A temporarily unoccupied and warm house is the perfect invitation for unwanted pests, rodents, and insects. Keeping your AC running at a slightly lower temperature can help deter unwanted guests from making themselves at home.
Potential Temperature Fluctuations: If you live in a hot climate, completely shutting off your AC leaves your home to the whims of the weather. Extreme heat in your home isn’t only uncomfortable to return to, but it can also pose health risks for pets and individuals with heat sensitivities.

Why You Should Leave Your AC On While On Vacation

As previously mentioned, turning your AC off while you are away risks causing costly damage to your home. Increased humidity can lead to mold growth, and sweltering temperatures can put stress on your appliances, such as your refrigerator and freezer. These appliances have to work harder to keep your food cold, which can increase your energy bill.

Electronics such as your television and video game systems are also at risk of getting damaged due to high temperatures. In extremely high temperatures, it can lead to cracked screens, damaged motors, and even melted circuits.

Special Cases

Weekend Trips

If you live in a moderate climate that doesn’t experience high humidity or temperatures, then you can turn off your air conditioning for short periods without risking damage to your home. Short weekend trips are not enough time to cause serious damage, so you can turn off your AC without having to worry.

However, if you live in the deep south or the desert where you experience high humidity levels and temperatures above 90 degrees Fahrenheit, it may be in your best interest to leave the AC on to help protect the inside of your home and your belongings. Keep your local climate in mind when deciding what you want to do with your thermostat while you are away.

Extended Stays

If your vacation is going to last for longer than a few days, then you can set your thermostat to a higher temperature than normal. The recommended range is anywhere between your normal temperature setting and 85 degrees Fahrenheit. This allows your AC to still circulate air and keep your home temperature-controlled without using as much energy. Your AC will run less set at 80 than it will at 72, so it will use less energy while still keeping your home and belongings safe from potential damage.

Other Ways to Save Energy While on Vacation

Although it’s not recommended to turn off your AC when you leave for vacation, we understand the reason behind homeowners doing so. You want to save money on your energy bill while you are away, and who doesn’t want to save a few bucks? However, there are other things you can do to help save energy while you are away that puts less stress on your home and comes with fewer risks.

Clean the Air Filters

One thing you can do to save money on your energy bills even when you are home is to clean out the air filters in your HVAC system. A dirty filter can decrease the efficiency of your air conditioning, causing it to have to work harder to circulate cool air throughout your home.

Changing the filters before you leave on your trip can make sure that your AC is running smoothly and efficiently while you are away.

Pull the Plug

Hold your horses, we don’t mean it like that! Think about how many things you have plugged in throughout your house. All of these electronics use energy even when they are not being actively used. Unplugging electronics such as televisions and light fixtures can decrease energy usage throughout your home while you are away and potentially save you money on your energy bill for the month.

Close the Blinds & Curtains

Not only will closed blinds improve privacy and prevent snoopy neighbors from looking in while you’re away, but they can also help regulate the temperature inside your home. During the summer, closing the blinds can block out the sun and help keep your home cooler, which in turn lessens the workload for your AC.

In the winter, closing the curtains can help insulate your windows and keep your home warmer, which means your heat will have to run less to maintain a comfortable temperature. No matter the time of year, this simple habit can save you money on your energy bill while you are enjoying a trip with your friends and family.

Lower the Temperature of Your Water Heater

A lot of water heaters have some sort of ‘vacation’ setting, which will lower the temperature that your water heater is maintaining. Your water heater will still run while you are away, but it will use less energy in the process. If you do this, be sure to turn this setting off when you get back and give your water heater time to heat back up to its regular temperature before you try using the hot water.

To Chill, or Not to Chill?

While it may seem like a good idea at first to turn off your AC before you leave for vacation, the potential savings on your energy bill are not worth the risk of serious damage to your home. A lack of air circulation and sweltering heat can lead to mold growth and damage to your electronics and other personal belongings. Safer ways to save energy include closing blinds and curtains as well as unplugging electronics before you leave for your family trip.

We’ll delve into the essential maintenance practices that can prolong the life of your air conditioning system.

This article will guide you through key maintenance steps and highlight the significant benefits of keeping your AC in top condition. From simple filter changes to professional inspections, understanding these practices will help you enjoy a cooler, more comfortable home while optimizing energy efficiency and minimizing repair costs.

The Ins and Outs of Your AC System

Getting to know the functional components of your air conditioning system is key to effectively managing its upkeep. Here’s a breakdown of the essential parts and their functions, ensuring you know precisely how your AC works and why each component is crucial:

Compressor: It’s an integral part of any AC unit. It has the task of compressing the refrigerant before helping it circulate through the AC system, enabling it to remove heat from your home.
Condenser Coil: This component sits in the outdoor part of the unit, tasked with releasing the heat removed from your home into the outside air.
Evaporator Coil: This component is situated inside your home as part of the air handler. As the indoor air passes over the refrigerant-filled evaporator coil it absorbs the humidity, effectively cooling your home.
Air Handler and Blowing Unit: These are two components that work in synergy to circulate air throughout a facility. The air handler ensures air moves past the evaporator coil to cool down while the blower unit pushes the cooled air through the ductwork.
Refrigerant: The lifeblood of your AC system, the refrigerant flows through the system and carries heat from the indoors to be expelled outside.
Thermostat: The thermostat is your system’s control center. It helps you determine the desired temperature and helps the unit maintain that temperature.
Expansion Valve: Positioned between the evaporator and condenser coils, the expansion valve controls the amount of refrigerant flowing into the evaporator, aiding in the cooling process.

Essential Maintenance Tasks

Preventive maintenance is essential for keeping your AC unit running efficiently and allowing it to operate without issues for an extended period of time. Such a proactive approach not only reduces the risk of unexpected breakdowns but also promotes a seamless operation that’s both cost-effective and reliable.

There are several aspects of your AC that you should focus on when performing preventative maintenance:

Filter Maintenance

The importance of air filter replacement and cleaning should not be taken lightly. Regularly tending to your air filters is a simple yet effective way to boost your AC’s efficiency and protect its longevity.

Firstly, a clean air filter ensures optimal airflow. When airflow is restricted by a clogged filter, your AC must work harder to circulate air through your home. Furthermore, clean filters contribute to healthier air quality in your home. They achieve this by trapping different particles such as dust or pollen, from the circulating air and removing them.

Regular filter maintenance also prevents dirt from building up in the system’s components, which can lead to more significant and costly problems down the road. The recommended frequency for changing air filters in your air conditioning system can vary, but a general rule of thumb is to check and potentially replace them every 30 to 90 days.

Coil Cleaning

The evaporator coil, typically located inside your home, is where the cooling occurs by absorbing heat from the circulating indoor air. The condenser coil, which is usually part of the external portion of the unit, releases this heat outside.

Together, these coils ensure efficient heat transfer to cool your indoor spaces. Keeping them clean is vital to sustaining your AC’s efficiency and prolonging its lifespan. Here’s how you can do that:

Turn off the power: Safety first. Ensure the power to the entire AC system is off before you begin your work on it.
Access the coils: For the evaporator coil, you might have to open the access panel on your indoor unit. The condenser coil is usually easier to access in the outdoor unit, but you may still need to remove a protective grille or cover.
Clean the coils: Gently remove large debris or leaves around the condenser coil. A refrigerator coil brush is the best tool for dusting off the coils, but any soft brush would do.
Apply coil cleaner: Use a commercial air conditioner coil cleaner. Follow the package instructions, spray it on, and let it foam and soak. Then, carefully rinse it with water.
Check and straighten the fins: Inspect the fins on the coils. If any are bent, straighten them with a fin comb, which helps maintain proper airflow through the coils.
Reassemble and restart: Once you’ve cleaned all the AC components, it is time to reassemble the unit usually by returning the cover panels. Restore power to the unit and check if it operates smoothly.

Seasonal Tune-Ups and Professional Inspections

When you schedule a professional AC tune-up, there are several key tasks you can expect the technician to perform to ensure your system is running efficiently and effectively. Here’s what typically happens during a professional AC tune-up:

Thorough Inspection and Cleaning

The technician will perform a detailed assessment of your AC system. This usually includes inspecting the thermostat settings to ensure the system starts, operates, and shuts off properly.

Expect the technician to clean key components such as the condenser and evaporator coils, which are crucial for efficient operation.

Checking Fluid Levels

Refrigerant levels are an important aspect of AC maintenance and are always featured in the professionals’ checklists. Ensuring an adequate level of refrigerant is crucial for uninterrupted cooling.

Examining Components

The technician will inspect the electrical components and connections to ensure they are operating safely. This includes tightening any loose electrical connections and running tests on the system capacitors.

Filter Replacement

Depending on the service agreement, the technician might replace or clean the air filters. This is essential to maintain high air quality and an uninterrupted airflow.

System Testing

After the maintenance tasks, the technician will run the system to ensure it’s operating smoothly. They will check the airflow and temperature output to confirm everything is in top condition.

When to Call the Professionals

Recognizing when to call a professional for your air conditioning system can save you time and prevent costly repairs. Here are some key signs that indicate it’s time to seek professional help:

Unusual noises: Any strange sounds you might hear from your unit, such as grinding, clattering, or squealing, could indicate mechanical issues that require expert attention.
Weak airflow or no cold air: When the air from your vents isn’t as cold as it used to be, or the airflow seems significantly weaker, these could be signs of blockages or failing parts.
Frequent cycles: An AC unit that cycles on and off more frequently than usual might be signaling an issue. This inconsistent operation can put a lot of strain on your system, eventually resulting in costly breakdowns.
Bad odors: Musty smells could indicate mold inside your unit or ductwork, while a burning odor might signal electrical issues. Both scenarios warrant a professional evaluation.
Rising energy bills: An unexpected increase in your energy bills could suggest your AC system is losing efficiency, often due to an underlying issue that a professional can diagnose and fix.

If you notice any of these issues, it’s wise to contact a certified technician who can provide a thorough assessment and resolve any problems, ensuring your system continues to run effectively and efficiently.

When choosing a service provider for AC maintenance, do not let cost be the determining factor. A reputable company is both certified and licensed to operate and provides the necessary insurance, safeguarding you against potential damages. Experience matters too; providers with a long track record are likely to offer reliable and knowledgeable service.

Most AC maintenance and repair tasks should be left to the professionals. However, there are several things you can do on your own to help improve the AC system’s performance.

One of the easiest things you can do on your own is to regularly clean your filters, or maybe replace them. Dirty filters restrict airflow, reducing the efficiency of your system. A good rule of thumb is to clean them monthly and replace them at least once during the what season to ensure proper airflow and cleaner indoor air.

Cleaning your AC system’s coils is another vital maintenance tip you can do by yourself. With regular use, these coils accumulate debris and dirt particles that can get in the way of heat transfer and reduce the cooling capacity of your AC. You only need a soft brush to clean the coils gently, or alternatively, you can use a vacuum cleaner.

Additionally, lubricating AC fan motors and belts can reduce the risk of your AC breaking down by way of preventing wear and tear. Ensure you use the appropriate lubricant recommended by your AC manufacturer to avoid any damage.

Conclusion

In conclusion, proactive AC care is essential for beating the summer heat and creating a comfortable, cool environment in your home. By understanding the importance of regular maintenance, recognizing signs that your AC system needs attention, implementing easy DIY tips, and seeking professional assistance, you can ensure optimal performance and prolong the lifespan of your AC unit.

With proactive AC care, you can stay cool, save on energy costs, and enjoy the summer months to the fullest. So, if you’d like to be prepared to beat the heat this summer, Sempre Fi Heating & Cooling has proactive maintenance strategies to cater to your needs.

Written by Hector Waldo on February 15, 2024. Posted in Air Conditioner Troubleshooting, Air Conditioner Tune-Up, Air Conditioning, Air Conditioning Repair, Air Conditioning Replacement, HVAC.

TL;DR: Installing a new HVAC system can cost between $5,000 to $12,000, but it’s a valuable investment for homeowners. Regular maintenance, costing $75 to $200, offers significant returns in energy efficiency and property value. Energy-efficient systems with modern features like smart thermostats attract buyers and fetch higher prices. Compliance with regulations and green certifications adds to desirability. Keeping professional maintenance records and following practical tips maximize HVAC value. Regular check-ups, filter replacements, cleaning, and choosing upgrades tailored to your needs ensure optimal performance and longevity. Overall, investing in HVAC maintenance is crucial for preserving property value and ensuring comfort.

Installing a new HVAC system can be a significant investment and cost homeowners anywhere from $5,000 to $12,000, depending on the system’s size and complexity. Unsurprisingly, most new home buyers see great value in properties equipped with a functioning HVAC system.

However, the condition of the HVAC system is closely tied to your property’s overall value. When the HVAC system runs perfectly, it saves energy costs and makes the property more attractive to potential buyers who recognize its value. So, let’s closely examine the ROI of HVAC maintenance, how it adds value to your property, and how to keep your system in perfect shape.

Calculating the ROI of HVAC Maintenance

If you are trying to understand the return on investment (ROI) of HVAC maintenance, start by considering your initial maintenance expenses. These include regular check-ups, part replacements, and repairs to avoid other issues. That will cost you around $75 to $200. That price tag might seem like a lot at first, but you must weigh it against the savings on buffer repairs.

Savings come in several forms, notably through energy efficiency. When your system is well-maintained, it can run on less energy, meaning lower utility bills. Similarly, regular maintenance includes replacing all worn-out parts and extending the unit’s life.

If you have an HVAC system running without issues, that can help you increase the value of your property if you ever decide to sell. Properties that have systems with environmental certifications can fetch a higher price. This increase in market appeal contributes positively to your ROI, making the investment in maintenance even more worthwhile.

Increased Property Value Through Energy Efficiency

Real estate buyers are more aware of the long-term benefits and savings of having energy-efficient features in your home. As a result, properties with modern HVAC systems often attract the attention of energy-conscious buyers. A recent study found homes with energy-efficient features sell more often and at a higher price point.

Modern HVAC systems operate more efficiently, using less energy to heat and cool the home, translating into significant savings over time. For your HVAC to be energy efficient, it must have at least a SEER 14 rating. Modern systems use the latest technology to maintain optimal temperatures and use minimal electricity compared to outdated HVAC units. That can reduce your property’s carbon footprint, which will likely appeal to potential buyers.

Improving Indoor Air Quality

Recently, Mesa, Arizona, has had issues with air quality, so you must ensure the air you breathe indoors is better quality. You can upgrade the HVAC system with high-efficiency air filters or add air purifiers to reduce the presence of pollutants and allergens.

These pollutants are not just outdoor intruders like pollen and dust. They include indoor particles such as pet dander, household chemicals, and mold spores. Not having them in the air can help you be more healthy.

Having your HVAC not contribute to low air quality can make your property more appealing and increase its value. Prospective buyers or tenants often look for homes that promise a healthy living space, and if their new home already has an air-purifying system, that is one less expense they have to worry about.

The Appeal of Smart HVAC Technology

Prospective homebuyers are looking for homes that are not only move-in ready but also equipped with modern conveniences that make life easier. Smart thermostats and HVAC systems offer them total control over the home’s temperature directly from their smartphone or voice-activated devices. They can even teach the system their preferences, and it can automatically adjust the settings for maximum comfort.

Beyond comfort, these systems are also more energy-efficient, translating into potential savings on utility bills. They usually come with detailed usage reports, helping homeowners understand their energy consumption and identify further opportunities for savings.

Regulatory Compliance and HVAC Systems

You might already be aware that various regulations and standards dictate how HVAC systems should operate within homes. These rules cover everything from installation and maintenance to efficiency and emissions. Ensuring your HVAC system complies with these standards prevents potential fines and makes your home more attractive to future buyers. It’s a straightforward equation: compliance equals desirability.

Green certifications, such as Energy Star or LEED, are benchmarks of efficiency and sustainability for HVAC systems. Such certifications prove that your HVAC system effectively heats or cools your home with less energy, significantly reducing your home’s overall carbon emissions. That is a main selling point in today’s market, where energy efficiency and environmental responsibility are increasingly important to buyers.

Professional Maintenance Records as Proof of Care

When you sell your home, potential buyers want assurance they’re making a wise investment. Keep your maintenance records as proof that you’ve cared for the HVAC system, following regulatory standards and best practices for system upkeep. These records can show potential buyers that the HVAC system is in excellent condition and won’t need expensive repairs or replacements shortly after purchase.

Practical Tips for Maximizing HVAC Value

Your HVAC system can add the most sales value to your property if you inspect and maintain it regularly. Maintaining your HVAC system won’t be burdensome if you stick to a servicing schedule. Some of the things you can regularly do are:

Replace HVAC system filters every three months, but possibly more often if you have pets or live in a dusty area.
Keep the area around your outdoor units clear of debris and foliage. That allows your system to breathe easier, improving efficiency and prolonging its life.
The indoor unit can collect dust and other particles that affect air quality and system performance. Ensure the coils and blower components are clean, which will help your system operate more effectively.
Dust and debris can accumulate in your ducts over time, blocking airflow and forcing your system to work harder, which, in turn, can lead to increased energy costs and reduced system lifespan. Duct cleaning is something you should entrust to a professional, but still do often.
Regular professional check-ups by HVAC specialists at least once a year can help catch any potential issues before they become big problems, saving you money in the long run.

Tips on Choosing HVAC Upgrades

Energy-efficient HVAC models can be a more significant initial investment but often pay for themselves through lower utility bills. Smart thermostats are another excellent upgrade, allowing homeowners to control the heating and cooling remotely and set more efficient schedules. When selecting these upgrades, consider your home’s size, climate, and specific needs to ensure you’re making the most cost-effective decision.
