average lifespan of heat pump system
1 According to the Air Conditioning, Heating & Refrigeration Institute (AHRI), the average lifespan of a heat pump is approximately 14-15 years.2  A 2006 survey by the National Association of Home Builders (NAHB) found the average life expectancy for a heat-pump system was 16 years.he weather in your geographic area has a significant impact on the longevity of a heat-pump system. With colder, longer winters, heat pumps will put in more hours of use each heating season, shortening its lifespan to some degree. Another factor that impacts lifespan is the consistent maintenance given to the system.
