Have you recently had a new furnace installed and are now experiencing a weird smell? You're not alone, because many other homeowners also experience this at first. Let’s review what’s creating this smell, and when you can anticipate 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 smell.
Your furnace has a special coating on specific 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 operates for the first couple of times, the coating may emit a burning smell. This is normal and the smell should dissipate the more your furnace runs.
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 has overheated or there’s an electrical problem, among other issues.
Dust collects inside your furnace when it’s idle 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 go away within a few minutes.
One way you can reduce or prevent this smell is by having furnace maintenance done every 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 require 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 covered in plastic to protect against shocks, and this smell is a sign that heat is melting this protective coating. To avoid a fire, turn off your furnace right away and have it inspected out by an HVAC technician.
- Gas or rotten eggs. Gas companies include sulfur in natural gas to warn you when there’s a leak. If your furnace smells like gas or rotten eggs, turn it off right away, evacuate your home and call 911. Exposure to natural gas can make you ill, plus it’s extremely 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.
