Have you recently had a new furnace installed and are now noticing an unusual smell? You're not alone, because many other homeowners also experience this at first. Let’s review what’s causing this smell, and when you can expect 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 stink.
Your furnace has a special coating on specific parts to keep them from rusting. This may include the heat exchanger, which safely exhausts gases such as carbon monoxide naturally produced during the heating process.
When your furnace runs for the first couple of times, the coating may give off a burning smell. This is standard and the smell should go away 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 sticks around can mean the motor is too hot 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 turn 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 necessary to keep your valuable manufacturer’s warranty valid, 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 can happen. 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 problem. Electrical wiring is coated in plastic to protect against shocks, and this smell is a sign that heat is melting this protective coating. To prevent a fire, shut off your furnace immediately and have it inspected out by an HVAC technician.
- Gas or rotten eggs. Gas companies add sulfur to natural gas to alert you when there’s a problem. If your furnace smells like gas or rotten eggs, shut it off immediately, leave your home and dial 911. Exposure to natural gas can make you sick, plus it’s highly flammable and explosive.
- Musty. If your furnace smells musty, you might have mold and mildew flourishing in your ductwork. We recommend having your ductwork inspected and cleaned if needed.
