What is the average life expectancy of a heat pump?
Saturday, June 1, 2019
While not an exact predictor, average lifespan is still a valuable piece of information. Here’s the average lifespan for different types of air conditioners:
- Split System Heat Pump Condenser (outside unit) - 10 to 16 years
- Split System Heat Pump Air Handler (inside unit) - 14 to 18 years
- Ductless (Mini-Split) Heat Pump - 10 to 16 years
- Package Units Heat Pump- 10 to 16 years
- Heat Pump Window Unit - 5 to 8 years
According to the Social Security Administration, the typical 65-year old American can expect to live to the age of 83. Some will depart this world sooner, and about 10% will live to 95. Old air conditioners are much like that. It’s easy to find out the average lifespan, but pinpointing the month when the service van will pull up to take away your old unit and cart in a new one is just not possible.
Although the condenser (outside unit) of a split system tends to have a shorter life than the air handler, because a replacement condenser must now be matched for performance (by the manufacturer or certified by an engineer) with the indoor evaporator coil portion of the air handler, the evaporator coil unit may have to also be replaced when the condenser fails.
Regular maintenance is a good way to beat the odds and make your heat pump system last longer, and most HVAC contractors offer a service plan with annual or twice a year visits.
Many people refer to both an air conditioner ("straight cool” or “cooling”) and a heat pump as simply an “air conditioner,” but an air conditioner requires an electric resistance heat coil or combination with a gas or oil furnace for heating, whereas a heat pump can reverse the flow of refrigerant to heat the home. Most heat pumps have electric resistance heat anyway as a backup for very cold days.
