Air-Conditioning and Heat Pump Efficiency 101. At some point during their ownership, many homeowners may have to replace their central air-conditioning systems. The average life span of central air-conditioning system is 12- to 15- years if it is properly installed and maintained.Heat pumps have about the same life-span â about 14 years â when recommended maintenance is followed. Newer units manufactured in recent years are expected to last even longer.n the past, homeowners could sometimes replace part of their system, such as the outdoor condensing unit, to extend its useful life. However, air-conditioning and heat pump systems manufactured today must have a seasonal energy efficiency ratio (SEER) of 13 or higher.
