How Long Does a Gas Furnace Last?

How long does a gas furnace last?

As winter weather settles in and you get ready to turn on your old furnace you may wonder just how much longer it will keep running. The general answer is about 20 years. But the answer is more complicated and depends on a lot of factors. Some of these factors include how well made the furnace is and whether it is a lower cost or more expensive higher end model. If it's a lower cost furnace it may be ready for replacement in as little as 8 years.

Thankfully, many of the factors that determine how long a furnace will last are under your control. The most important thing you can do is have your furnace professionally maintained every year. This will not only make the furnace last longer, it will help it operate more efficiently and reduce the cost of unexpected repairs.

Because most gas furnace parts can be replaced as they wear out, it's usually a good idea to repair the unit as parts wear out. The one part that usually ends the life of a furnace is the heat exchanger. Constant heating and cooling will eventually cause the heat exchanger to rust out or crack, leading to failure. With new gas furnaces operating at much higher efficiency than units made just 10 years ago, replacing the furnace may be more cost effective in the long run when compared to the repair cost of keeping a 10-15 year old furnace running.
