Why Is There a Burning Smell When I Turn On the Heater?

Furnace Repair in Huntsville, AL

It’s not uncommon to notice a burning smell when your heater is on, especially when you turn it on for the first time in months. While it can be a sign there’s something very wrong with your heater, it can also be a minor issue.

Dust in Your Furnace

When you haven’t used your furnace in months, dust collects inside it. When you turn the furnace on, the dust will combust and produce a burning smell. This smell should clear up within an hour or so and isn’t anything to be concerned about.

Alabama Climate Control, Inc. in Huntsville, AL, offers a heater tune-up service. We clean the inside of your furnace, so you won’t have a burning smell when you use it after months of not needing it.

Debris in Ducts

It’s possible something fell into your ducts and is producing a burning smell when it’s heated up. If the smell is in just one room of your home, open the register and look inside the duct for debris. Remove the object and see if that resolves your problem.

Dirty Furnace Filter

If the furnace filter is dirty, it can produce a burning smell. Check the filter and replace it if it looks dirty. You should replace the furnace filter every other month to prevent a burning smell and other problems.

Damaged Wiring

A burning electrical smell when your furnace is on indicates there’s likely some wiring that is damaged. Electrical wiring can break down due to wear and tear. You should schedule an appointment with an HVAC company to resolve this problem.

Blocked Flue

If you have a gas heater, combustion gasses are vented outside your home. When the flue becomes blocked, the gasses have to go somewhere and can enter your breathable air. If you smell smoke when your furnace is on, turn it off and call an HVAC company.
