Signs You Should Replace Your Home Heating System

If you take care of your furnace, you can expect it to last 15 to 20 years. If it’s been neglected, it might last just 10 years or less. There are signs your furnace is wearing down and in need of replacement.

Major Repairs

If your furnace needs a major repair, it’s probably time to replace it. This is especially true if the repair will cost over half of what you’ll pay for a replacement. You may also run into a situation where replacement parts are difficult to get.

High Energy Bills

Furnaces lose their efficiency over time. This results in higher energy bills every year. New furnaces are more efficient than ever, and with proper maintenance, they’ll keep your energy bills low for years to come.

Yellow Flame

A properly working furnace will have a bright blue flame. This shows it’s cleanly burning gas and there are no safety issues. If your furnace has a yellow flame, it might just need to have the heat exchanger and burner cleaned. It can also mean there’s a serious problem and the furnace needs to be replaced.

Uncomfortable Home

When furnaces get old, they lose their ability to heat your entire home. It might send too much heat into some rooms while other ones get too little. This makes for an uncomfortable home that can only be fixed by installing a new furnace.


When you replace an old furnace, you reduce your carbon footprint. Highly efficient furnaces have a less negative impact on the environment and climate change.
