Foul Furnace Odor? Here’s What To Do

There’s nothing that can put a damper on your home like a heating problem in the middle of the cool weather season. You expect your furnace to be able to do its job and keep you warm, but you also expect it to perform to a certain level. The last thing you want to do is notice a foul odor coming from your home’s furnace. If you notice an unusual smell in your home whenever you run your system, then it’s time to get furnace repair in Longmont, CO

We typically put a sense of urgency behind all furnace services especially if it has to do with any type of foul odor. Furnaces are combustion-based systems that typically run on natural gas. This means that the possibility of a problem with carbon monoxide is there. Don’t wait until the problem increases in severity. Contact us at the first sign of an issue.

Odd Scents You Might Notice

There are multiple different scents that you might notice coming from your heater. Here are a few you should note and contact a professional about as soon as possible. 


Are you noticing a burning smell going on in your home? Burning is a scent that you never want to notice when you turn on your system. Most of the time, you’re going to notice burning when it’s an electrical issue.

This can happen due to the age of your furnace. As your furnace ages, bearings can wear down and cause dysfunction. A byproduct of this is often your system heating up enough to wear down your home’s wire insulation. Don’t ignore this smell. It’s definitely dangerous and can result in electrical fires if left unattended. 

Rotten Eggs

Have you noticed the smell of rotten eggs? If you do notice this type of scent, then you’re nursing an urgent issue. This is likely the smell of a natural gas leak at some level. You might be dealing with this if you also notice dizziness, chronic nausea, fatigue, or a general sense of sickness. 

Natural gas isn’t something that has a scent on its own. This is what makes it so dangerous. Gas companies add a special chemical to create this sulfuric scent as a safety precaution to alert you to the presence of gas. Make sure that you’re heeding this warning by contacting one of our team members. 


Does your home smell dusty or stale? This can happen when your furnace accumulates dust over time. It settles on your system and, as it heats up, the dirt burns off and might smell like smoke, dirt, or dust. This is something that you should contact one of our team members over. We’re qualified to help you rid your home of this problem. 

Dirty Socks

Does your home start to smell like a high school locker room when you run your heater? This is a bad sign. If you’re noticing this, then it’s probably because some type of bacteria can built up on the coils in your system. We can help you rid your home of this.
