Have you recently had a new furnace put in and are now having a weird smell? You’re not alone, because many other homeowners also have this happen at first. Let’s review what’s leading to 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 smell.

Protective Coating

Your furnace has a special finish on certain parts to keep them from rusting. This may include the heat exchanger, which safely gets rid of gases including carbon monoxide naturally produced during the heating process.

When your furnace starts for the first couple of times, the coating may give off a burning smell. This is normal and the smell should dissipate the more your furnace heats.

To be on the safe side, you’ll want to contact a heating and cooling company if the smell continues. A burning smell that remains can mean the motor is too hot or there’s an electrical problem, among other concerns.

Dust

Dust accumulates inside your furnace when it’s not running in the summer. That dust will burn off when you flip on your furnace in the fall, producing a burning smell. This smell should subside within a few minutes.

One way you can decrease or prevent this smell is by having furnace maintenance done every single year. This is needed to keep your valuable manufacturer’s warranty good, plus it keeps your furnace clean and ensures it will run properly during the upcoming heating time of year.

3 Other Furnace Smells You Shouldn’t Ignore

While it’s less common for a new system to necessitate furnace repair, it can happen. Here are three other odors you should watch for and what they might mean.

  1. Burning plastic or rubber. If your furnace smells like burning plastic, you might have an electrical problem. Electrical wiring is covered in plastic to prevent shocks, and this smell is a signal 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.
  2. Gas or rotten eggs. Gas companies add sulfur to natural gas to warn you when there’s a leak. If your furnace smells like gas or rotten eggs, turn it off right away, leave your home and contact 911. Exposure to natural gas can make you sick, plus it’s highly flammable and explosive.
  3. Musty. If your furnace smells musty, you might have mold and mildew growing in your ductwork. We advise having your ductwork checked and cleaned if required.
