Have you recently had a new furnace put in and are now experiencing a strange smell? You’re not alone, because a lot of other homeowners also experience this at first. Let’s review what’s leading to this smell, and when you can anticipate it to disappear, as well as three other furnace smells you shouldn’t ignore.
Why Your New Furnace Smells
There are two factors why a new furnace might smell.
Your furnace has a special application on specific 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 operates for the first couple of times, the coating may give off a burning smell. This is standard and the smell should dissipate the more your furnace runs.
To be on the safe side, you’ll want to call a heating and cooling company if the smell persists. A burning smell that sticks around can mean the motor is too hot or there’s an electrical problem, among other concerns.
Dust builds inside your furnace when it’s idle in warm weather. That dust will burn off when you turn on your furnace in the fall, making a burning smell. This smell should go away within a few minutes.
One way you can lessen or prevent this smell is by having furnace maintenance done each year. This is needed to keep your valuable manufacturer’s warranty applicable, 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 require 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 difficulties. Electrical wiring is covered in plastic to protect against shocks, and this smell is a signal that heat is melting this protective coating. To avoid a fire, shut off your furnace as soon as possible and have it checked out by an HVAC technician.
- Gas or rotten eggs. Gas companies include sulfur in natural gas to signal you when there’s a leak. If your furnace smells like gas or rotten eggs, turn it off right away, get out of your home and dial 911. Exposure to natural gas can make you sick, plus it’s very flammable and explosive.
- Musty. If your furnace smells musty, you might have mold and mildew growing in your ductwork. We suggest having your ductwork checked and cleaned if necessary.
