Furnace lifespan: how many years does a gas furnace last?

The right time to think about your furnace lifespan is not when you wake up in the middle of a January night and realize that it’s suddenly freezing in the house.

The age of the furnace may not be your biggest problem

One of the big issues facing older furnaces isn’t necessarily age, it’s availability of parts.

How do I get my furnace lifespan to last longer?

The easy answer is proper maintenance. A simple cleaning and inspection by a licensed professional can add several years to the life of your gas furnace. Maintenance isn’t only an issue of longevity but safety as well. A proper inspection includes a look at all of the major parts including items like the heat exchanger that if malfunctioning could emit deadly carbon monoxide gases into the home.
