Everything Homeowners Need To Know About AC Lifespan, Performance, and Replacement

How long do central air conditioning systems last—and what should you do if your home's AC isn't working at peak performance? If you suspect that it's time to replace your air conditioner, take a look at what you need to know about AC lifespan, parts replacements, and everything you as homeowners need to know about a new installation.

What Is the Average Lifespan of a Central AC Unit?

Conventional wisdom and most research show that the average expectancy of a central air conditioner ranges from fifteen to twenty years. But these numbers will vary greatly based on many factors, including the actual operational age and degree of proper maintenance on your home AC system.

Does Age Equal Replacement Time?

No, as mentioned - age is not the only predictor of the need for a replacement AC system. There are different variables that relate to “life expectancy”. These variables include the initial quality of the system, the quality of the initial installation, and regularity of the professional maintenance or care for the system. Even diligent air filter replacements have a serious effect on the overall lifespan of your home's cooling system. Failure to schedule regular seasonal service, changing the air filter, or having a highly qualified HVAC technician repair minor problems could result in the need for a premature replacement. 



How Do You Know if the Air Conditioner Doesn’t Work at Peak Performance?

The indoor air temperature and humidity level are easy ways to tell if the system is working or not. If the system blows warm air through the vents or the indoor air feels moist and humid, it's likely that your cooling system is not working or not working well. Other indicators of a system on the decline include long cooling cycles (when it takes longer for the system to reach the desired temperature than it should (or it has in the past) and higher than normal – for the season - electricity bills.

The Department of Energy notes that a brand-new system could save a homeowner 20 to 40 percent compared to a 10-year-old air conditioner. Not only are older systems less efficient from the start, years of wear and tear can slow the air conditioner down and cause your utility bills to rise. 

Is a Full Replacement Your Only Option (SEER-2 Rules)?

When you decide that replacing your system(s) is the right thing to do, it’s important to understand the latest laws associated with the HVAC industry. There are now “SEER-2” requirements that are put out by the US Dept. of Energy. All professional licensed companies such as Environmental Air Systems who replace or install new air-conditioning systems must do so with AHRI rated equipment that guarantees the efficiencies and adhere to regional efficiency standards. This means that the combination of all components (think outdoor unit with indoor coil, and the air-handler or furnace of each new system must be certified with a specific SEER-2, EER-2, and HSPF (for heat-pumps) AHRI number. With that in mind, our experienced staff can explain more, review the latest types, models, and capacities of air conditioning systems that will best fit your home cooling needs and budget. We can also provide you with information on air quality products that make for a healthier living environment which can be installed with your new high-quality equipment. Don’t forget that EASI also offer excellent financing to make it much easier!
