In general, most HVAC systems will last 15 to 25 years, but depending on the type of system and other contributing factors, that estimate can be highly variable. Even with HVAC maintenance and regular repairs, eventually, even the best boilers, furnaces, heat pumps, and air conditioners today will run their course.

Central air conditioning systems can last anywhere between 10 to 30 years, with most averaging around 10 to 15 years total (1). Keep in mind, the lifespan of your air conditioner depends on how much you use it, your local climate, what type of AC it is, and if your house is well insulated and air sealed.

Heat pumps normally last an average of 15 years, though some can wear out after a decade. Some of the newer units being manufactured today can last a bit longer. The factor most important in determining the lifespan of your heat pump is maintenance.
