When it comes to anticipating the life of heating and cooling equipment, the average life expectancy is not as defined as with other pieces equipment in the home. Generally the better quality equipment will usually outlast the less expensive “builder installed” models.
There is really no way of knowing how long equipment will last, it is not unusual for us to inspect a furnace and air conditioner that is thirty years old and fully functional.
Average life expectancy (in years) for Heating & Cooling equipment are as follows:
- Gas forced air furnace 18-25
- Oil forced air furnace 15-20
- Electric (Resistance) heat 20-30
- Geothermal 20-25
- Heat pump 10-15
- Central air 12-18
- Mini Split 18-22
- Window AC 10-25
- Package Unit 15-20
- Cast-iron boiler 30-50
- Steel boiler 15-30
- Circulating pump 10-20
- Oil Tank 35-40
NOTE: These are averages and should only be used as a guide when making decisions.
