Why Does My Furnace Smell Like Burning?

When you heat your home, you don’t want to be smelling a burning odor any more than you would want to while cooking your dinner. Furnaces generate heat via the combustion of fossil fuels or with electric resistance. Regardless of the type of furnace that you use, a burning odor is never a good sign. That is why you should contact a member of our staff the moment that you smell burning when you run your heater. While you should never attempt to repair your furnace on your own, we do think that you should have an idea of why your furnace smells this way. Read on to learn more.

Dust Burning Off

If it is very early in the heating season when you smell burning coming from your furnace, it may be due to dust that has built up in its off season burning off. This dust may build up on the gas furnaces burner assembly, for instance, and will be ignited when the furnace comes on for the first time. This is not necessarily a major concern, but you should let us know if the odor persists beyond the first couple of uses.


If your furnace continues to smell like burning, it could be the result of a component within that furnace overheating. Often, the fan motor is the culprit. If you are not diligent in changing your furnace’s air filter, it can create a lot of airflow resistance within your system. When this happens, your system is going to have to work harder than it should in order to force air throughout your home. This can result in the overheating of the fan motor.


Does the burning odor coming from your furnace have a plastic-y odor to it? If so, you need to contact us immediately. This could be the result of burning wiring, and that is a serious fire risk.
