Why Does My Furnace Smell Like…?

When something goes awry with your furnace, you’ll often notice an accompanying smell. In this blog post, our goal is help you associate those furnace smells with the necessary repairs. And, of course, if you decide you need furnace repair in the Gaithersburg or Frederick, MD areas—we know a guy you can call (hint: it’s us. We’re the guy.).

Why Does My Furnace Smell Musty?

If your home is filled with a musty, dry, or dusty smell when you turn your furnace on, you most likely have dust in your combustion chamber. Changing your filter can help! If the smell persists after this, call a professional for further inspection.

Why Does My Furnace Smell Like Gas?

Be careful with this one! If you own and operate a gas furnace, you should be well aware that carbon monoxide is a by-product of its combustion. When your gas furnace is not operating as efficiently as it should, excess and dangerous amounts of carbon monoxide can be produced.

So when you smell gas, it’s usually best to call your gas company in case of a gas leak to avoid fire, explosion, or carbon monoxide poisoning.

Why Does My Furnace Smell Like Rotten Eggs?

Natural gas is actually odorless. A compound is added to it by utility companies to give off a smell so you can more easily detect a gas leak. If you smell rotten eggs or sulfur, this could be a sign that you have a natural gas leak. Shut off your gas supply line (if you know how to) and call your gas company.

If you have a propane furnace and you smell rotten eggs, it’s possible that you’re low on fuel.

Why Does My Furnace Smell Like Burning?

Does your furnace smell like an overheated iron? It’s possible that one of your furnace’s electrical components has failed—especially if you don’t have your system regularly maintained. Call an HVAC company for an inspection.
