Have you recently had a new furnace installed and are now noticing a weird smell? You're not alone, because many other homeowners also have this happen 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 disregard.
Why Your New Furnace Smells
There are two reasons 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 gets rid of gases like carbon monoxide naturally produced during the heating process.
When your furnace runs for the first couple of times, the coating may emit 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 lingers can mean the motor has overheated or there’s an electrical problem, among other concerns.
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 lessen 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 properly during the upcoming heating season.
3 Other Furnace Smells You Shouldn’t Ignore
While it’s less common for a new system to require furnace repair, it can happen. Here are three other smells you should look out for and what they might mean.
- Burning plastic or rubber. If your furnace smells like burning plastic, you might have an electrical issue. Electrical wiring is coated in plastic to protect against shocks, and this smell is a sign that heat is melting this precautionary 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 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 inspected and cleaned if necessary.
