Have you recently had a new furnace put in and are now having an unusual smell? You’re not alone, because plenty of other homeowners also have this happen at first. Let’s review what’s leading to this smell, and when you can expect it to go away, as well as three other furnace smells you shouldn’t ignore.
Why Your New Furnace Smells
There are two reasons why a new furnace might smell.
Your furnace has a special coating on certain parts to keep them from rusting. This may include the heat exchanger, which safely removes gases like carbon monoxide naturally produced during the heating process.
When your furnace starts for the first couple of times, the coating may emit a burning smell. This is standard and the smell should disperse 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 is too hot or there’s an electrical problem, among other issues.
Dust builds inside your furnace when it’s off 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 decrease or prevent this smell is by having furnace maintenance done each year. This is required to keep your valuable manufacturer’s warranty applicable, plus it keeps your furnace clean and ensures it will run smoothly during the upcoming heating season.
3 Other Furnace Smells You Shouldn’t Disregard
While it’s less common for a new system to require furnace repair, it happens. Here are three other odors you should look 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 covered in plastic to prevent shocks, and this smell is a signal that heat is melting this protective coating. To avoid a fire, turn off your furnace as soon as possible 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 problem. If your furnace smells like gas or rotten eggs, shut it off as soon as possible, leave your home and call 911. Exposure to natural gas can make you unwell, plus it’s highly flammable and explosive.
- Musty. If your furnace smells musty, you might have mold and mildew growing in your ductwork. We advise having your ductwork examined and cleaned if necessary.
