Why Does My Furnace Smell?

What’s that funky odor coming from your furnace? When it comes to home heating, a foul odor is one of the many signs that indicate you have trouble on your hands. Should this happen when you least expect it, here’s how to detect the underlying problem and what you can do about it:

Electrical Issue
Do you detect a burning plastic smell? The culprit could be a stuck object in the ductwork that gives off an odor when it gets overheated. Inspect your registers and remove all of them to look for a dropped toy or a spill. If you suspect it’s a more serious issue, call a professional HVAC technician to come take a look.

A moldy odor usually means that mold is trapped in the furnace filter. An easy solution (and preventative) is to change the filter. If your furnace has a humidifier attached to it, be sure to inspect the filter annually and replace or clean as often as needed. That way, your humidifier filter won’t collect mold and cause a foul smell.

Smoke is one of the more alarming smells we can detect. You might have a blocked chimney, which can send smoke back through the furnace and into the ductwork. So if you suspect that your chimney is clogged, call your HVAC pro.

Typically, changing the filter can prevent complications with your furnace. But if you’re unsure about where the problem is coming from or how to fix it, give your expert HVAC tech a call.
