What Sort of Lifespan You Should Expect from Your Furnace

IMG_8221One of the more common questions that we hear from customers is how long they should expect their air conditioner or heater to continue to work before replacing it. People in Southern California usually have a good idea about air conditioner lifespans considering how much work those units put in every year. But the situation is a bit shakier when it comes to heating systems. Heaters are a necessary part of comfort during the year, but they do less work than air conditioners.

We’re going to take a closer look at the life expectancies of the most common type of home heating system, the furnace—as well as ways to see that your furnace lasts for as long as possible.

The average furnace

In the most general terms, a forced-air furnace should last between 15 to 20 years. Electric furnaces will tend to be on the upper part of that range because they have fewer moving parts and do not have the wear and tear from the reaction of combustion gases with metal. However, natural gas furnaces will often make it to 18 years.

Although furnaces can get past 20 years of service, a furnace that is over 25 years old could justifiably be replaced—even if it seems to be working fine. At this age, the furnace is going to be close to the end of its service life, is using a lot more energy than new technology in heating, maybe a CO2 danger, and is likely to break down at any moment. You should never wait for a furnace to break down before replacing it!

Furnace life expectancy depend on you as well

It’s important to understand that the above estimates are for a furnace that receives regular professional maintenance and care. If you neglect routine service for your furnace, as well as scheduling repairs whenever the system needs them, then the furnace may not may it far beyond 10 years—and perhaps may need replacing sooner than that. Always work closely with professionals to see that you get the most years from your furnace.
