Imagine turning on your heater on the first cold day of the season, and it smells like it’s burning. This happens for several reasons; some are simple fixes, while others require professional help.
Dust: If a heater sits dormant all summer, there’s a good chance it’s filled with dust. Dust builds up on components like the heat exchanger and burners and emits a burning odor when you turn it on. This is normal; the smell will disappear once the dust has completely burned off.
Old Furnace Filter: Many people have a terrible habit of not changing their filters regularly. A clogged filter impedes your system’s performance and can be responsible for the burning odor as mold and mildew accumulate. If changing the filter doesn’t remove the smell, you may need to invest in getting your ductwork cleaned.
Something in the System: If your heater emits an odor of burning plastic or robber, it could mean something lodged in the ducts or the system that shouldn’t be there, like kids’ toys or another foreign object.
Electrical Issues: If your furnace or heater emits an electrical odor, shut it off and call a professional technician as soon as possible. Wear and tear or shoddy installation could damage the system’s wiring, leading to odor and other complications.
The best way to reduce or eliminate foul heater odors is by hiring a professional like Superior Plumbing, Heating & Air-Conditioning, Inc. for annual maintenance and tune-ups.
