4 Smells That Shouldn’t Come from Your Furnace in Lebanon, TN

January 23, 2024

If you notice strange smells coming from your Lebanon, TN furnace, it’s important to find out what they mean. You want to catch any issues before they become more serious. Discover more about the sources of these four common furnace smells now.

Rotten Egg/Sulfur Scent

If you smell something like rotten eggs coming from your home’s furnace, reach out for immediate help. The smell of sulfur, which resembles that of rotten eggs, typically indicates a gas leak. Get everyone out of your home as quickly as possible, and call for professional repair.

Musty Smell

If your furnace emits a smell that’s similar to the scent of a musty basement, there’s probably something wrong. In many cases, you can remedy this issue by changing your HVAC filter.

Locker Room Odor

If your furnace smells like a sweaty gym bag or locker room, you’re probably dealing with some sort of bacterial growth within the system. Since all HVAC systems produce some sort of condensation, it’s possible for bacteria to form inside your system. You can avoid this problem by scheduling regular HVAC maintenance.

Ozone/Electrical Burning Smell

It’s natural for you to panic if your furnace emits a burning odor. It’s normal to notice a burning smell for a short period when you use your heating system for the first time this year, as the system burns away dirt and dust that builds up on it while the system isn’t in use. However, if this odor persists, you need to turn the HVAC off and call for professional help.

While some smells aren’t a cause for concern with your furnace, it’s a good idea to know what to look out for and be cautious. Contact Derryberry’s Heat & Air today for help with your furnace repair and replacement needs.
