Have you recently had a new furnace set up and are now experiencing a strange smell? You’re not alone, because plenty of other homeowners also experience this at first. Let’s review what’s leading to this smell, and when you can expect it to go away, as well as three other furnace smells you shouldn’t disregard.

Why Your New Furnace Smells

There are two explanations why a new furnace might stink.

Protective Coating

Your furnace has a special finish on specific parts to keep them from rusting. This may include the heat exchanger, which safely removes gases like carbon monoxide naturally produced during the heating process.

When your furnace runs for the first couple of times, the coating may release a burning smell. This is normal and the smell should dissipate the more your furnace operates.

To be on the safe side, you’ll want to connect with 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 problems.

Dust

Dust accumulates inside your furnace when it’s off in the summer. That dust will burn off when you switch 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 applicable, 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 need furnace repair, it can happen. Here are three other scents 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 difficulties. Electrical wiring is covered in plastic to prevent shocks, and this smell is an indication that heat is melting this precautionary coating. To prevent a fire, shut off your furnace immediately and have it checked out by an HVAC technician.
  2. Gas or rotten eggs. Gas companies include sulfur in natural gas to alert you when there’s a leakage. If your furnace smells like gas or rotten eggs, shut it off right away, leave your home and contact 911. Exposure to natural gas can make you unwell, plus it’s very flammable and explosive.
  3. Musty. If your furnace smells musty, you might have mold and mildew flourishing in your ductwork. We advise having your ductwork checked and cleaned if necessary.
