Have you recently had a new furnace installed and are now noticing a strange smell? You’re not alone, because plenty of other homeowners also experience this at first. Let’s review what’s creating this smell, and when you can expect it to go away, as well as three other furnace smells you shouldn’t disregard.
Why Your New Furnace Smells
There are two explanations why a new furnace might reek.
Your furnace has a special finish on specific parts to keep them from rusting. This may include the heat exchanger, which safely gets rid of gases including carbon monoxide naturally created during the heating process.
When your furnace runs for the first couple of times, the coating may emit a burning smell. This is typical and the smell should go away the more your furnace operates.
To be on the safe side, you’ll want to call a heating and cooling company if the smell continues. A burning smell that sticks around can mean the motor has overheated or there’s an electrical problem, among other issues.
Dust collects inside your furnace when it’s off in the spring and summer. That dust will burn off when you flip on your furnace in the fall, creating a burning smell. This smell should disappear within a few minutes.
One way you can decrease or prevent this smell is by having furnace maintenance done each year. This is required to keep your valuable manufacturer’s warranty valid, plus it keeps your furnace clean and ensures it will run smoothly during the upcoming heating time of year.
3 Other Furnace Smells You Shouldn’t Ignore
While it’s less common for a new system to need furnace repair, it happens. Here are three other smells you should keep an eye out for and what they might mean.
- Burning plastic or rubber. If your furnace smells like burning plastic, you might have an electrical problem. Electrical wiring is coated in plastic to avoid shocks, and this smell is a sign that heat is melting this protective coating. To prevent a fire, shut off your furnace right away and have it checked out by an HVAC technician.
- Gas or rotten eggs. Gas companies add sulfur to natural gas to alert you when there’s a problem. If your furnace smells like gas or rotten eggs, shut it off immediately, evacuate your home and call 911. Exposure to natural gas can make you sick, plus it’s extremely flammable and explosive.
- Musty. If your furnace smells musty, you might have mold and mildew growing in your ductwork. We recommend having your ductwork checked and cleaned if required.
