  • What Is the Average Lifespan of an Air Conditioner?

    Energy Air

    Whether or not to get a new HVAC system is a big decision. You might be wondering what is the average life of an air conditioning unit? Should I replace mine? Is it even time?

    According to the US Department of Energy, the average lifespan of an air conditioning unit is about 15 to 20 years. But there are a few factors to consider when deciding whether or not your HVAC system needs to be replaced.

    Factors to Consider When Replacing Your AC


    If you have an older air conditioner, you might want to replace the outdoor compressor with something more efficient – if not the whole system. Even if your air conditioner is only 10 years old, keep in mind that today’s best air conditioners use 20 percent to 40 percent less energy for the same level of cooling.

    New central air conditioner standards went into effect on January 1, 2015, so you may want to review them and be sure that your existing system meets these requirements.

    SEER Rating

    Another factor in AC life expectancy is going to be your unit’s SEER rating. SEER stands for the Season Energy Efficiency Ratio, and it’s a number used to measure how much cooling an HVAC system can put out for every 1 unit of energy it consumes. Old efficiency requirements were set to 10 SEER. Today, HVAC systems are designed to operate at least 13 SEER — or to be 30 percent more efficient. Older systems generally only have SEER ratings of 6 — not taking into account a drop in efficiency over time.

    R-22 Usage

    Your AC is most likely nearing the end of its life expectancy if it’s 10-13 years old. Another sign that your AC is on the way out is if it’s using an R-22 refrigerant. R-22 is an ozone-depleting chemical that was recently determined to be harmful to the environment. If your system uses the R-410-A refrigerant, that means it’s new enough that it’s probably not at the end of its life.

    Review your HVAC system and look at its ratings. As we touched on earlier, if your unit is only rated to be 10 SEER or less – it’s probably time for an upgrade (your electric bills will thank you).

    Overall Efficiency

    Another measure you can check is your furnace’s Annual Fuel Utilization Efficiency (AFUE) rating. The current national regulations call for an 80% AFUE, so if yours is only rated 60 to 70 percent AFUE then your system is very dated and may be at the end of its lifespan.
