The first time you turn on your Weird Furnace Smells? in the winter it may emit a funky, burning dust smell. This is normal and not a reason to be alarmed, as your furnace burns off all the dust that accumulated over the summer. If the smell doesn’t disappear after a few hours, you should call a professional.
Is it bad if your furnace smells?
Musty odors are more concerning as they could indicate mold or other moisture issues in your home. If the odor continues to persist even after running your heater for several hours, call Allbritten for an inspection as soon as possible.
A rotten egg scent near your furnace is a sign that you have a gas leak in your home. Natural gas suppliers add a substance known as mercaptan to the natural gas supply to make leaks more easily detectable. If you notice a rotten egg smell around your furnace, immediately shut off the gas to your house and leave it switched off until a technician has inspected it.
If you notice an electrical or metallic smell around your furnace, it could mean that some components are overheating. If the odor is particularly bad, such as a burning plastic or rubber odor, shut off your heater and contact Allbritten to schedule an inspection right away.
An oily smell from your furnace is another warning that you need to get it checked out by a professional. This could mean that the air filter is clogged and needs to be replaced, or it may indicate an oil leak.
