How Long Does An HVAC System Last On Average?

You just had an epiphany! You’ve lived in your home for almost 10 years and never have replaced your HVAC unit.

This begs the question, “How long does an HVAC system last?” As a homeowner, it’s essential to know the answer.

Read our guide to find out more.

How Long Does an HVAC System Last?

To answer the question, “How long does an HVAC system last?”, is not so simple. This is because there are different parts to a unit that may last longer than others.


A furnace can last at least 15 years, if not upwards of 25 years, depending on how well it’s maintained. The lifespan of an HVAC unit that has a furnace will also depend on the size of the unit.

To last a full life, the furnace must be sized properly in correlation with the home.

Air Conditioning Unit

The HVAC lifespan of an air conditioning unit is about 15 to 20 years. If you want the unit to live a long life, you’ll need to complete a maintenance check on it at least two times per year.

Like the furnace, it needs to be the correct size for your home.

When the air conditioning is run frequently like in areas with a warm climate, the lifespan tends to be in the 15-year range.

Heat Pump

A heat pump can last up to 16 years. Because a heat pump may run more often, it’s often outlived by a furnace.

If you want your heat pump to last as long as possible, get it maintained by a professional at least once a year. During the maintenance service, the heat pump also needs to be cleaned thoroughly.

Tankless Water Heater

A tankless water heater can last up to 20 years. However, the longevity of this unit depends on the water quality in your area.

If the water quality isn’t great, the water heater is going to have to work harder, which leads to a shorter life.

Maintenance is required less for a tankless water heater. You can get away with a complete maintenance check every three years.

Electric or Gas Water Heater

A traditional water heater, one that is electric or gas-powered, can last around 10 years. To maintain regular water heaters, flush them out yearly and have them looked at by a technician every three years.


Thermostats can last up to 25 years so you shouldn’t have to replace them for a long time. Yet, because smart thermostats are becoming a new thing, many opt to replace their thermostat before the end of its life.
