Air conditioners are sturdy pieces of equipment that are designed to last a fairly long time. Most experts agree that the usual lifespan of a residential A/C unit should be between 15 and 20 years. That sounds really good, doesn’t it? However, you should be aware of some aspects.


The numbers above represent the lifespan of an air conditioner under ideal circumstances: professional installation, regular operating conditions, proper care and maintenance. In reality, poor installation or extreme weather conditions, among others, will shorten the operational life of an A/C unit.


What Other Aspects Influence the Useful Life of an Air Conditioner?

If you want to get the most out of your air conditioner, you should have it periodically serviced and maintained. Also, simple things like removing dust with a vacuum cleaner and replacing air filters will allow you to enjoy your A/C unit for a longer time.


However, when it has reached around two thirds of its average operational life (8-9 years) it may show signs of breaking down. In this situation, you should think hard whether it’s worthwhile to have Denver AC repair technician repair it or buy new. If the cost with workmanship and replacement parts exceeds about one third of the cost to install a new A/C unit, then it is not worthwhile. Instead, start looking for a new air conditioner.
