How Long Do HVAC Systems Last?

Your HVAC system is a large investment, so you’ll likely want to see it last as long as possible. There isn’t a straightforward answer to how long a system will last as it depends on several factors. In general, though, it can be expected to last 15 to 25 years.

Factors Impacting Your HVAC Systems Lifespan

How Long Do HVAC Systems Last?The number one thing affecting how long your system will last is regular maintenance. Getting your HVAC system tuned-up annually by a professional technician will ensure that it lasts as long as possible.

The quality of the installation work will also affect the lifespan. If the installer didn’t follow proper installation procedures, the HVAC system will have a shorter life. This includes putting in an oversized or undersized system, which leads to much shorter lifespans. Oversizing, for instance, results in frequent on and off cycling that causes part failures. Techno Air Heating, Cooling and Refrigeration of Grove City correctly installs gas furnaces along with other HVAC equipment.


You can expect your well-maintained gas furnace to last about 20 to 30 years. It’s usually when the heat exchanger cracks that the furnace needs to be replaced. Electric furnaces tend to last longer.

Air Conditioners

The average air conditioner can be expected to last 15 to 20 years. They are located outside, so they don’t tend to last as long as indoor HVAC equipment does.

Heat Pumps

Heat pumps usually last 10 to 20 years. They operate as a heater and air conditioner and get more use than furnaces and air conditioners do.


Boilers typically last 20 to 35 years. Like gas furnaces, it’s usually when the heat exchanger becomes cracked that a boiler needs to be replaced.
