Furnace Smells Burnt | General Heating and Air Conditioning

Why does my furnace smell like it’s burning?

You smell something, and you aren’t quite sure what it is. Your nose leads you to your furnace, and now you are just puzzled as to why your furnace is making a burning smell. What could be wrong?

One easy solution: This time of year, the first uses of the season, your furnace will be burning off all the dust that accumulated throughout the summer months. Therefore, the odor you smell could be your furnace gearing up for the season ahead.

If this is still happening after you use your furnace a few times, there may be another issue happening.

But there isn’t necessarily reason to panic.

Your air filter could be clogged. If the filter is clogged, the blower motor has to work harder to overcome the particles clogging the filter. When the blower motor is working harder, it can start to overheat, causing a burning smell. Additionally, if your filter is clogged, you can also have excess dirt build up on your furnace, which could also cause a smell.

Another reason for a burning smell is the result of an electrical issue. If this is the case, you want to try to get it fixed quickly, as electrical issues are fire hazards and threaten your safety.  To help prevent these issues before they begin, you want to change your air filter regularly.

If you aren’t sure or aren’t comfortable trying to fix the issue yourself, you want to contact a professional. Something like this could often be dealt with during an annual furnace tune-up since the internal parts are cleaned and the technician will check over parts. As an example, see our Home Comfort Program page and click on “Learn More Information” to see what we include in a tune-up.
