How long does an Air Conditioning unit last?

The answer depends on several factors, and our team will be more than happy to provide customized estimates for your individual situation. Generally speaking, the average life span of an AC unit is 20 years if maintained properly.

We recommend scheduling a precision tune-up, professional cleaning and safety inspection once a year. Regular maintenance will extend the ACs lifespan, and it will also reduce pollutants, reduce the risk of potentially dangerous malfunctions and maintain performance (see Doug’s Annual Maintenance Agreement for more).

ACs are more likely to last longer if they aren’t used excessively and if they were sized and installed correctly. Re-evaluating and optimizing your current system may add years to its life; however, there are clear signs your older AC is approaching the end of its lifespan:

  • Your energy bill has risen tremendously.
  • Your AC requires frequent repairs.
  • Your AC starts to make unusual noises.
  • Your AC is producing a funny odor.
  • Your AC starts leaking.

We recommend comparing the benefits of repairing older units versus installing a new system. A new system will cost more in the short term, but its improved energy efficiency will save you money in the long run. Consider replacing your AC when the savings of a new unit become higher than the cost it takes to repair and maintain the old unit.
