When it comes to dirty air conditioning vents, it is important to know what to look for. Common signs of dirty AC vents include dust or other debris accumulation, an unpleasant smell, loudness (caused by the fan or blower motor), reduced airflow, and increased energy bills.

Dust and debris accumulation are some of the most common indicators of AC vents that have become dirty. When dust and debris accumulate on the vents, they will usually be visible, so this is a type of sign that will be easy to spot. In fact, your AC vents probably would not need to be this dirty very often, so if you notice an accumulation of dust, it is likely time to get them cleaned.

Another indicator of dirty AC vents is an unpleasant odor. This odor is often caused by the dust and debris that have built up over time. When the dust accumulates, it is likely that the air blowing through the vents will pick up the odors and disperse them, making the space seem stale and musty.

When it comes to dirty AC vents, another sign is loud fan or blower motor noises. Vents rely on pressure in order to operate correctly, and dirt and debris can cause issues by blocking pressure. Blocked pressure causes the fan or blower motor to work overtime in order to overcome the blockage, and this can lead to a loud and unpleasant noise.

Also, if you have noticed that your AC vents are not blowing as much air, or if your energy bills have been higher as of late, then these are likely also signs of dirty vents. When vents are blocked, airflow is reduced and the motor has to work harder in order to push the same amount of air. This leads to higher energy bills, and if you have noticed your bills have gone up recently, then you should check your vents.

All in all, if you suspect that your AC vents may be dirty, then you should keep an eye out for all of the signs and symptoms described here. A professional cleaning may be necessary in order to clear out any dirt or debris and restore your AC vents to their optimal performance.

What Size Furnace Do You Need?

Hint: Bigger Isn’t Better

Time will come when your old furnace is not worth attempting to repair. You can live with rattles, squeaks and uneven heating in your home. You could even live with small repair bills. But no heat on a cold night is over the limit. It will be time to look for a new furnace. Then, don’t think about moving up to a larger-capacity furnace unless you know your old furnace is undersized. An oversized furnace usually creates more problems than it solves.

It’s Less Efficient

A properly sized furnace is an optimally sized furnace – not too big and not too small. Every time a furnace starts up for a heating cycle, it takes a few minutes to warm up. During the warmup, it is operating at less than peak efficiency. After it is warmed up, it operates at peak heating efficiency. An oversized furnace may warm up the house too quickly and shut down before or shortly after the warmup. Repeat that over and over all day and all night and the furnace is always operating less efficiently than it should.

Life Expectancy

Over years of service, the on again/off again cycles will cause excess wear to system controls and ultimately shorten the lifespan of the large furnace. An optimally sized furnace is more efficient and will have a longer operational life. A well-maintained, high-quality, properly sized furnace should provide efficient heating for 15-20 years or more.

Short Cycling

A common problem with oversized furnaces is called short cycling. It happens when sensors in the furnace cause it to overheat and shut down before the house has warmed up. The oversized furnace produces more heat than the system needs. The most positive identifier of short cycling is when the thermostat’s two temperatures—room temperature and thermostat set temperature—never match. Short cycling is a safety hazard. If sensors fail to shut the furnace down, the furnace is a real fire hazard. The end result of short cycling is that the house is not comfortable, fire risks increase, and the life of the furnace is reduced.

Distribution of Heat Will Be Uneven

It isn’t unusual for one area of a house to be cooler or warmer than others. Replacing a properly sized furnace with an oversized furnace will not solve the uneven heat problem; it will make it a bigger problem. The comfortably warm areas in the house will become overly warm and the cool rooms may not get any warmer.

The Language of HVAC – 10 Terms You Should Know

Most people think they know the meaning of many of these furnace and air conditioning terms. It’s actually a little more complicated than that.

  1. What do the letters HVAC stand for? Heating, Ventilation, and Air Conditioning. In other words, furnace, air conditioner and some method of circulating warm and cool air throughout a house. H-VAC is the generally accepted name for the entire industry.
  2. A furnace creates heat. It does that by burning natural gas, bottle gas, heating oil, or electrical heating coils. Not all furnaces create heat with the same amount of energy usage. Nearly all new furnaces are more energy efficient than their not-so-distant replacements, but a well-maintained furnace in a well-insulated home can operate efficiently for many years.
  3. An air conditioner produces cool air, but, like a furnace, some do it more efficiently than others. Typically, the years of operational life are fewer for an air conditioner; a fifteen-year air conditioner is usually approaching the time when repair costs begin to mount, and replacement seems like a good option.
  4. An air handler is the part of the ventilation system that draws in warm or cool air for the furnace or air conditioner to turn it into cool or warm air, respectively, then blows it out into ducts that deliver it throughout a home. While operating, an air handler continuously circulates home air. Along with ductwork and a blower, an air handler is the V in an HVAC heating and cooling system.
  5. There are two sets of ducts in a conventional central air heating and cooling system. Air flows through intake ducts to your furnace and air conditioner and is discharged into a second duct system that delivers it to the rooms of a home. The same air circulates over and over, getting heated or cooled along the way.
  6. Smart thermostats truly are smart, and they get smarter over time. A smart thermostat will observe the time you wake up, go to work, return home, and go to bed. Then it adjusts its settings to match your daily routine. It will even observe that your house is empty for multiple days and adjust accordingly. With a connected smart thermostat, you can even send it a message that you are on the way home and it will have your house comfortable when you arrive.
  7. Ductless, or ductless mini-splits, as the name implies, do not have ducts to circulate air. Small units are located in one or several rooms. They can provide heat or cooling or both. They are excellent for keeping a newly added room or garage comfortable or even an entire house.
  8. Heat pumps are energy-efficient heating and cooling systems. A heat pump does its job by moving heat. In the summer, it removes heat from a house and discharges it outside. In winter, it draws heat from outside and circulates it inside. Contrary to common logic, there is plenty of heat outside on even the coldest days.
  9. Internal Air Quality (IAQ) is a measure of the pollutants in the air circulating in a home. The main line of defense against dirty air is the air filter in the home heating system. Heating and cooling professionals have a variety of other options to clean harmful gases and particles from indoor air.
  10. SEER is short for Seasonal Energy Efficiency Ratio, sometimes called Seasonal Energy Efficiency Rating. SEER ratings are given to heating and cooling systems to help consumers evaluate energy efficiency. Ratings range from 13 to 25. As of January 1, 2023, SEER 13 is the lowest approved efficiency rating by government mandate.

Save Energy with a Heat Pump

Way back in the middle of the 19th century, an Austrian named Peter von Rittinger observed that forests in upper Austria were being cleared to use as fuel for producing salt from naturally occurring salt brine. He developed a process to evaporate water from salt brine using 80% less energy than boiling away the water over a wood fire. He called his device a steam pump. Today, we refer to systems performing similar functions as heat pumps.

Modern heat pumps are used for both heating and cooling. They remain one of the more energy-efficient systems for heating and cooling. There are two types of modern heat pumps. Geothermal, also known as ground source, utilizes heat from underground or underwater and condenses it to produce heat or cooling to distribute through a home. Air-sourced heat pumps take in outside air to do the same thing. Both types are capable of keeping your home warm in winter and cool in summer.

Why Consider a Heat Pump?
  1. Most HVAC industry information recommends that a conventional central heating and cooling system should be replaced every 10-15 years. Well-maintained systems may last longer, but eventually repair costs get higher and higher as more expensive components start breaking down. Air conditioners usually fail before furnaces, but often it is best to replace both units at the same time. Heat pumps have a longer life expectancy; 20-25 years is not uncommon. For a house that is expected to last a normal lifetime, replacing the conventional central heating and cooling system may be needed two or three times. A heat pump may only need to be replaced once.
  2. Heat pumps require less maintenance. A once a year preventative maintenance and service check is all that is needed. Conventional systems should be checked twice a year. Not only does a heat pump need repair less often, when it does need repair it is likely to be less expensive. Heat pumps have fewer parts to break down and require replacement than conventional systems.
  3. Heat pumps are more energy efficient; utility bills will be lower. Heat pumps use electric-powered fans to circulate air around a home, but they do not directly consume fossil fuels to produce heat. In most homes without a heat pump, the central heating and cooling system is the largest user of energy.
  4. Over their lifespan, most conventional air conditioners develop refrigerant leaks. The leaks get repaired with regular maintenance and more refrigerant is added. The missing refrigerant has leaked out into the air as environmental pollution. Replacing refrigerant is costly, and dispersing the refrigerant into the atmosphere is harmful. Heat pumps do not use refrigerant. There is nothing to leak and cause environmental harm.
  5. A downside to heat pumps is that generally they are more expensive than conventional central heating and cooling systems. Over years of lower utility bills, fewer and less expensive repairs, less routine maintenance, and fewer replacements, a heat pump is usually a less expensive option despite the higher initial cost.

Energy Usage in Your Home

Typical homes contain dozens if not hundreds of energy-consuming parts. Heating and cooling systems, light bulbs, refrigerators, coffee makers, vacuums, and many more items in your home depend on electrical energy to operate. Let’s take a look at the energy users and learn more about which consume the most electrical power.

Heating and Cooling Systems

It is very likely that your HVAC system is the largest energy user. Even if you heat your home with natural gas, bottled gas or oil, the heated air does not circulate around your home without a blower that is powered by an electric motor. Ceiling fans are great to keep warm air circulating; ceiling fans are powered by electric motors.

Conventional air conditioners are big users of electrical energy. Electrical-powered compressors generate cool air and electric motor-powered blowers circulate the cool air. Heat pumps and geothermal systems are highly efficient for heating and cooling. They use the natural heat in the air and underground to heat and cool your home. But they require electric motors to pump and circulate the air and coolant that heat and cool the home.

In most homes, the heating and cooling systems are the largest user of electrical power. These systems typically account for nearly 50% of your total energy usage. Your toaster oven and hair dryer may be energy hogs, but they only get used occasionally. Your heating and cooling system operates nearly year round and nearly 24 hours every day.

Refrigerators and Freezers

Refrigerators and freezers are appliances that also require electrical power 24/7/365. Modern refrigerators are well insulated and well-sealed, making them highly efficient. A full freezer with solidly frozen food and a good seal is especially efficient. The frozen foods themselves keep the temperature low with the compressor motor seldom needing to run. Less than 5% of total home electrical usage should be attributed to refrigerators and freezers.

Water Heater

A conventional tank-type water heater requires 10-12% of energy usage. Gas-burning water heaters use much less electrical power, but gas is still part of home energy costs. The greatest inefficiency in a tank-type water heater is they keep water hot 24/7/365—all day, all night and all through your out-of-town vacation. A tankless water heater only heats water as you use it, making it significantly more efficient. The energy savings is not enough to justify replacing a working tank-type water heater, but when the tank needs to be replaced, it is a good idea to consider tankless.

Washer and Dryer

Laundry machines are big electrical users, using as much as 12-15% of total electrical usage. Power usage can vary significantly depending on the number of loads to be washed and dried. Newer machines with larger capacities make it possible to wash fewer loads with improved operational efficiency.

Lights and Other Appliances

Light bulbs, microwave ovens, computers, televisions, phone chargers, coffee makers, cooling fans, power tools, and all other small appliances account for the balance of home electrical usage. Most of these items are only used occasionally, while some are on 24/7/365. Think of the little lights in your doorbell button, your coffee maker, and charging station that indicate power is on.

Make a count of all of the items in your home that require electricity. Don’t be surprised if there are over 100 light bulbs and at least 50 small electric-powered devices. Individually, they don’t consume much electricity, but collectively they can account for nearly a quarter of total usage.

Look for efficiencies in all areas. Look to your heating and cooling system for the biggest efficiency improvement. Keep your home a little cooler in winter and a little warmer in summer. Keep your heating and cooling system in good working condition, and get it tuned up every year. When it comes time for a replacement, purchase a high-efficiency system from Semper Fi Heating & Cooling.

Signs That a Heat Pump Needs to Be Replaced

Heating and cooling systems are complex mechanical/electrical systems. They work hard with repeated cycles day and night year-round to keep your home warm and cool. Conventional central furnace and air conditioning systems typically have a lifespan of 10 to 15 years. Heat pumps tend to have a longer life expectancy of 15 to 20 years. A few years before your heat pump needs to be replaced, you may start to see signs that it is not operating at peak efficiency. You may experience warm and cool areas within your home, or it may just take longer for it to get to the temperature you have it set for.

Repair Frequency

Initially, HVAC technicians can make repairs to get your heat pump back into good condition. Occasional repairs can be expected at any time. If your heat pump is more than 12 years old and the repair frequency begins to occur more often, you could be seeing signs that a replacement is going to be needed in the next few years. You may find that more and more worn-out parts need to be replaced. When the cost of repairs add up to half the cost of a replacement, then it is time to look seriously at replacement.

Run Cycles

Normally, your system should cycle as your thermostat tells it to turn on and off. If it is staying on longer than usual or running constantly, there is a problem. It is time to call a service technician to diagnose and repair the problem. It is possible that you have a thermostat problem, and your thermostat can be repaired or replaced. It is also possible that you have a heat pump problem that needs attention. It could be an early sign that a replacement will be needed soon.

Air Quality

Stale air and humidity are also signs of a malfunctioning heat pump. If you notice a difference in your interior air quality, your heat pump should be inspected. A heat pump that is nearing its life expectancy can cause changes in air quality.

Other Signs

Low coolant is a likely sign that there is a coolant leak that needs to be repaired. If you find that your heat pump is no longer keeping you warm in winter and cool in summer, it is probably approaching replacement time. Rising energy bills when there has not been a rate increase is a sure sign that your heat pump is becoming less energy efficient. You should seriously consider getting your heat pump replaced in order to lower your energy bills.

Are you hearing noises from your heat pump that weren’t there before—especially grinding and banging? Then, it is time to get it inspected and get a service technician’s opinion if a replacement is needed. A carbon monoxide leak is a serious potential health problem for your entire family. If your heat pump has a carbon monoxide leak, it is definitely time to make arrangements for replacement without delay.

Why Is No Warm or Cold Air Coming Out of Some of My Vents?

If the vent is open, and if it is properly connected to the ductwork, then the problem is probably an air intake vent. The fundamental principle of a central heating and air conditioning system is that room air is drawn into ducts where it moves to a central unit for heating and cooling. Then, it’s blown out other ducts and into your home from the air supply vents as warm or cool air. Eventually, the air is drawn back into the intake vents and the circulation cycle continues over and over. Along the way, the circulating air provides other benefits.

Filter Pollutants

As room air makes its way through air intake, ducts, heating or cooling, supply ducts and out the supply vents, it passes through a filter. The filter is your first defense in keeping harmful particles out of the air that you breathe.

There are other systems that can be installed to kill the germs that are circulating in your indoor air. The REME HALO is a highly recommended air purification system that you can install in ductwork, but it is not a replacement for the air filter. For clean air, there is no replacement for heating and cooling system air filters. Use a good filter and change it often. Once or twice a year is not enough. Use good filters, buy them in bulk, and change them frequently. The cleaner the filter, the cleaner the air in your home.

Maintain Air Pressure

Your HVAC heating and cooling system is a recirculating system. When warm or cool air comes out of the supply vents, an equal amount of air must go into the intake vents. Your home has been engineered for balanced airflow. If the intake vents are blocked or otherwise inadequate to balance the supply vents, the system will not work properly or efficiently. The heating and cooling system of your home demands balanced airflow. You may find that some are not heating and cooling as well as others.

If intake vents are blocked, your system still attempts to blow the same amount of air out of the supply vents. Pressure in the ducts will increase, causing the blower to work harder, which will increase your utility bills. Additionally, the pressure will cause ducts to leak, which will increase costs even more. Increased wear on your blower will eventually reduce the lifespan of your system.

It is important that you do not put furniture in front of air intake vents. Do not put rugs over them; do not close or obstruct them in any way. Nothing comes out of intake vents, but it is very important that unobstructed air be able to go into them.

Contact Semper Fi Heating & Cooling

With the high temperatures in Arizona, it is important that your heating and cooling system perform as it has been engineered to operate. Remember, change your filters often and do not obstruct your air intake vents. If you have questions about the operation of your system, get in touch with the expert technicians at Semper Fi.

Keeping Your Air Conditioner Operating Better and Longer

Lifespan of an Air Conditioner

Your air conditioning system is one of the bigger investments you make for your home. Like other equipment you purchase, your air conditioner will eventually wear out. Questions we often hear are, “How many years should an air conditioner last before needing to be replaced? How do I get a longer life out of my air conditioner?” There are no universal guidelines. We have serviced units that are 25 years old and replaced units that are 10 years old.


The long and scorching hot summers in Arizona mean that air conditioners work hard day and night for many months every year. Air conditioning systems in Arizona are generally on the shorter side of lifespans than they are in cooler climates. A lifespan of 10 to 12 years is about average for Arizona.

An air conditioner that has been well serviced on a regular schedule will last longer than an infrequently serviced system. Poor maintenance like not changing the filter often and not having routine tune-ups can cut the life of your air conditioner in half. If you are diligent about tune-ups ad preventive maintenance, you could increase the life of your system to double the average. A 20-year-plus lifespan for a well-maintained system is possible even in Arizona.

What YOU Can Do to Extend the Life of YOUR Air Conditioner
Change the Filter

The simplest, easiest and most important thing you can do is to change the filter often. The filter keeps dirt and grime out of your air conditioner as well as out of the home air that you breathe. A dirty filter will impede the airflow into your air conditioner, causing it to overheat. Dirty air can also cause electrical problems. Changing the filter is simple and easy, and it will reduce repair requirements and add extra life to your entire system.

Keep YOUR Condenser Clean

The condenser is the outside unit of your air conditioning system. Being outside, the condenser is exposed to the weather year-round. Leaves, grass, bushes and debris can block the clean airflow into your condenser unit. Keep the area around your condenser clean and give your entire system years of additional life.

Install a Smart Thermostat

Cooling your house when no one is home is a waste of energy and a missed opportunity to enjoy the benefits of a high-efficiency air conditioning system. A smart thermostat can adapt to your lifestyle, keep you comfortable when you are home, and extend the life of your air conditioning system.

Professional Tune-Up

The professional technicians at Semper Fi Heating & Cooling will perform a 29-point professional tune-up that includes a complete unit inspection, light coil cleaning and a written report of findings. If repairs are needed, have them done immediately. Your investment in time, attention and professional repairs will significantly extend the life of your air conditioning system while keeping your home cool and energy efficient for many years.
