Have you recently had a new furnace installed and are now having 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 expect it to go away, as well as three other furnace smells you shouldn’t ignore.

Why Your New Furnace Smells

There are two factors why a new furnace might stink.

Protective Finishing

Your furnace has a special finish on certain parts to keep them from rusting. This may include the heat exchanger, which safely exhausts gases such as carbon monoxide naturally created during the heating process.

When your furnace runs for the first couple of times, the coating may give off a burning smell. This is typical and the smell should disperse 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 has overheated or there’s an electrical problem, among other concerns.

Dust

Dust builds inside your furnace when it’s off in warm weather. 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 lessen or prevent this smell is by having furnace maintenance done every single year. This is required to keep your valuable manufacturer’s warranty applicable, plus it keeps your furnace clean and ensures it will run properly during the upcoming heating period.

3 Other Furnace Smells You Shouldn’t Dismiss

While it’s less common for a new system to need furnace repair, it happens. 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 issue. Electrical wiring is protected in plastic to protect against shocks, and this smell is an indication that heat is melting this protective coating. To prevent a fire, switch 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 signal you when there’s a leakage. If your furnace smells like gas or rotten eggs, turn it off as soon as possible, evacuate your home and contact 911. Exposure to natural gas can make you unwell, plus it’s extremely flammable and explosive.
  3. Musty. If your furnace smells musty, you might have mold and mildew flourishing in your ductwork. We suggest having your ductwork checked and cleaned if necessary.
