Have you recently had a new furnace installed and are now experiencing an unusual smell? You're not alone, because a lot of other homeowners also experience this at first. Let’s review what’s causing this smell, and when you can expect it to disappear, 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 stink.
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 like carbon monoxide naturally created during the heating process.
When your furnace operates for the first couple of times, the coating may give off a burning smell. This is normal and the smell should dissipate the more your furnace heats.
To be on the safe side, you’ll want to call a heating and cooling company if the smell continues. A burning smell that lingers can mean the motor is too hot or there’s an electrical problem, among other issues.
Dust collects inside your furnace when it’s not running in the spring and summer. That dust will burn off when you switch on your furnace in the fall, creating a burning smell. This smell should disappear within a few minutes.
One way you can lessen 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 properly during the upcoming heating season.
3 Other Furnace Smells You Shouldn’t Disregard
While it’s less common for a new system to need furnace repair, it happens. Here are three other smells you should watch for and what they might mean.
- Burning plastic or rubber. If your furnace smells like burning plastic, you might have an electrical issue. Electrical wiring is covered in plastic to protect against shocks, and this smell is an indication that heat is melting this precautionary coating. To avoid a fire, turn off your furnace immediately and have it inspected out by an HVAC technician.
- Gas or rotten eggs. Gas companies add sulfur to natural gas to warn you when there’s a leak. If your furnace smells like gas or rotten eggs, shut it off immediately, leave your home and dial 911. Exposure to natural gas can make you ill, plus it’s highly flammable and explosive.
- Musty. If your furnace smells musty, you might have mold and mildew flourishing in your ductwork. We advise having your ductwork checked and cleaned if necessary.
