Have you recently had a new furnace installed and are now having a weird smell? You’re not alone, because a lot of other homeowners also have this happen 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 explanations why a new furnace might smell.
Your furnace has a special application on some parts to keep them from rusting. This may include the heat exchanger, which safely exhausts gases like carbon monoxide naturally produced during the heating process.
When your furnace starts for the first couple of times, the coating may release a burning smell. This is normal and the smell should go away the more your furnace heats.
To be on the safe side, you’ll want to contact a heating and cooling company if the smell persists. A burning smell that remains 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 turn on your furnace in the fall, producing a burning smell. This smell should go away within a few minutes.
One way you can reduce or prevent this smell is by having furnace maintenance done each year. This is necessary 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 necessitate 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 difficulties. Electrical wiring is covered in plastic to prevent shocks, and this smell is a sign that heat is melting this precautionary 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 warn you when there’s a leak. If your furnace smells like gas or rotten eggs, turn it off immediately, get out of your home and dial 911. Exposure to natural gas can make you ill, plus it’s very 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 required.
