Why Is There a Burning Smell Coming From My Heater?

1. Burning Dust

The most common cause of a burning odor coming from your heating system is dust being burned off after months of buildup. If this is the cause for the smell, it should go away after a few minutes. However, if the problem persists, give your local HVAC professional a call.

2. Clogged Air Filters

If you haven’t changed the air filter in your HVAC system in a while, it can become clogged and cause a burning smell when your heater kicks on. This can also make the system work harder than usual, creating a burning odor and a potential fire hazard. If this is the cause, change your filters immediately and schedule a maintenance appointment with a reliable HVAC company.

3. Electrical Issues

Burning odors can occur if the blower is about to burn out. Blowers have two purposes: to pump cool air in the home out during the heating process and to keep the temperature of the furnace in check. Blowers are designed to last for at least a decade or more, but running the blower too much can shorten its lifespan and cause it to burn out. If this is the case, it can produce a burning odor and can also be a fire hazard.
