Here are 5 signs that your furnace is dying.

How Long Does a Furnace Last?

The average furnace life expectancy is around 20 years. If your current furnace is nearing this age range, you should begin looking around for a new unit.

You don’t want to wait for a heating emergency and be backed in a corner with a rushed project on your hands.

One indicator may be recent repairs. Many parts of a furnace will start to go out around the same time frame. If you have had worked done more than once in a year or two, that is a good sign of an aging or dying unit.

Higher Electric Bill

As your furnace starts to fade and become less efficient, it has to work harder to heat. This will drive up your electric bill.

If you consistently have a higher bill, you may need to look to your furnace as the source of the issue.

One option you may be considering is going green with your heating and cooling.

Does Your House Stay Warm?

How long should a furnace last? As long as it actually heats!
