How Long Do AC Units Last?

How Long Do AC units last
A frequent question we get at A-Plus Energy Management, Air Conditioning & Home Solutions is “How long do AC units last?”

Home air conditioning units can last between 10-15 years with proper maintenance. That may seem like a long time, but if you purchased a home with an AC already installed, you might want to consider a tune-up and AC evaluation. Knowing when to service or replace your air conditioner can save you valuable time and money.

Today’s air conditioning equipment lasts longer than ever. With updated energy-efficient technology, an AC’s service life may last longer than the 10-15 years. Your AC’s lifespan may be reduced if its capacity is not matched up with the cooling load of your home. Oversized air conditioners tend to “short-cycle”, turning on and off rapidly, causing excessive wear on the AC’s compressor. If your compressor wears out after the warranty runs out, it’s probably time to upgrade to a new energy efficient air conditioner.

Even with proper maintenance, units that get heavy usage may not last as long as the norm. Areas with high humidity and summer temperatures can cut the lifetime of your AC in half. Most older air conditioners can only cool a house 15-18 degrees while newer units can cool a home by 20-25 degrees. A home air conditioner is more than a convenience for many families. During the hottest times of the year, it’s what keeps us comfortable. Like any machine, to get the most life out of your AC, follow up with regular maintenance.

When you wait ’til it breaks, it costs more to replace

AC technicianHow many times have you asked your AC technician, “How much longer will my AC last?” How many times have you ignored your technician when he recommended replacing the cooling and heating system? Have you even disregarded his urge to get a new unit when there was a spring or fall sale going on? Have the words, “Do I really need to replace it now?  It is cooling fine” come out of your mouth before?  You probably regretted all of the above statements when it happened on that hot summer day: your AC stopped cooling. Of course it would happen on a scorching day when temperatures are in the triple digits. At that point, it may be too late to take advantage of promotions—as you would guess, there are usually no sales in the middle of summer or winter (aka when you need them the most). Your next question then is, “How soon can you install my new AC system?” The answer is usually that there’s usually a bit of a wait to get the unit ordered and installed because demand is high.  It’s practically unheard of for mid-summer jobs to come at a discount as its takes the AC technicians longer to complete their jobs in the extreme summer heat. Furthermore, they usually have to work overtime to keep up.

Be proactive.  Don’t wait until your air conditioning and heating system breaks down!  If you do wait, you could be without air conditioning for a few days and it will cost more to replace.  You wouldn’t wait until your car has over 200,000 miles and hope you can drive it cross country.  While the average life of an existing AC system is 12-15 years, we find that many of the systems installed by A-Plus Energy Management, Air Conditioning, & Home Solutions last much longer. In addition, they are more efficient and cost less to operate and use the more “earth friendly” refrigerant, R-410a.  Don’t wait until it is too late.  Check with your AC company and get an honest answer from an AC technician you can trust.  If you are unsure, in the Austin area you can call A-Plus @ 512-450-1980 or email us at .

The Problem With Oversized AC Units

There is a common misconception about sizing your air conditioner when it comes to heating and cooling your home or business. Most people believe the larger the air conditioning unit, the faster it will cool or heat the room- thus lowering your electric bill. There is only slight truth in such a notion. Yes, the room in which you want to cool or heat will reach the ideal temperature much faster with an oversized unit, however simply heating or cooling is not the only function of an AC unit. Only part of the air conditioner’s function is dedicated to heating or cooling, the other part of the units function is to dehumidify the air, something many people tend to overlook, or not even consider.  It is the proper combination of acceptable humidity and temperature that creates comfort.

A home or business with a correct sized AC unit will run at the ideal length of time resulting in desired temperature and dehumidification.  With an oversized unit, the unit does not have ample time to properly remove enough water from the air. For you techies out there- When water vapor condenses on the coil of an oversized unit, there is not enough condensation on the coil to pass through the pan below. Even if the water were to reach this point, it has still not done its job dehumidifying the home due to the fact that there will not be enough water built up on the pan to eject from the unit entirely. This could result in the water evaporating and eventually makings its way back inside.

This alone would be a valid reason as to why people should avoid purchasing an oversized unit, however it is not the only one. Another aspect is overall cost. A larger unit will cost more money up front, and in the long run. Aside from that, the stereotype that it will save you money is vastly embellished.  Before you upsize your system because it is not keeping up, first check your home’s “energy well being”.  It makes more sense to repair duct’s or add insulation, and not to change the size of the system.

So how does one assure that they are purchasing a properly sized unit for their home or business?

Your best bet is to get a HVAC certified professional to assess your needs. A properly trained home analysis will suggest what is the proper size system for the home or business you are trying to cool. A-Plus Air conditioning and Home Solutions professionals will not only guide you through the building analysis, but offer suggestions to what suits your needs best, whether it is weatherizing your home or replacing your cooling and heating system with the proper size.  Check A-Plus out!!!
