Have you recently had a new furnace installed and are now noticing an unusual smell? You're not alone, because a lot of other homeowners also have this happen at first. Let’s review what’s creating 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 reasons 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 gets rid of gases like carbon monoxide naturally created 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 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 sticks around can mean the motor has overheated or there’s an electrical problem, among other concerns.
Dust accumulates 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 disappear within a few minutes.
One way you can decrease or prevent this smell is by having furnace maintenance done each 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 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 an indication that heat is melting this protective coating. To avoid 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 alert you when there’s a problem. If your furnace smells like gas or rotten eggs, shut it off immediately, evacuate your home and dial 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 growing in your ductwork. We recommend having your ductwork checked and cleaned if needed.
