Have you recently had a new furnace set up and are now having a strange smell? You’re not alone, because plenty of other homeowners also experience this at first. Let’s review what’s causing this smell, and when you can anticipate it to go away, 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 stink.
Your furnace has a special coating on certain parts to keep them from rusting. This may include the heat exchanger, which safely removes gases including carbon monoxide naturally made during the heating process.
When your furnace starts for the first couple of times, the coating may release a burning smell. This is typical and the smell should dissipate the more your furnace operates.
To be on the safe side, you’ll want to contact 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 concerns.
Dust builds inside your furnace when it’s not running in warm weather. That dust will burn off when you switch on your furnace in the fall, creating 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 every year. This is needed to keep your valuable manufacturer’s warranty valid, plus it keeps your furnace clean and ensures it will run perfectly during the upcoming heating season.
3 Other Furnace Smells You Shouldn’t Dismiss
While it’s less common for a new system to need furnace repair, it happens. Here are three other odors 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 problem. Electrical wiring is coated in plastic to protect against shocks, and this smell is a sign that heat is melting this preventive coating. To prevent a fire, shut off your furnace immediately 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 leakage. If your furnace smells like gas or rotten eggs, turn it off right away, get out of your home and contact 911. Exposure to natural gas can make you unwell, 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 examined and cleaned if needed.
