Have you recently had a new furnace put in and are now having an unusual smell? You’re not alone, because plenty of other homeowners also have this happen at first. Let’s review what’s causing this smell, and when you can anticipate it to disappear, 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 reek.

Protective Finishing

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

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

To be on the safe side, you’ll want to connect with a heating and cooling company if the smell persists. A burning smell that sticks around can mean the motor is too hot or there’s an electrical problem, among other issues.

Dust

Dust accumulates inside your furnace when it’s not running in the spring and summer. That dust will burn off when you switch on your furnace in the fall, making 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 single year. This is required to keep your valuable manufacturer’s warranty good, plus it keeps your furnace clean and ensures it will run smoothly 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 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 covered in plastic to prevent shocks, and this smell is a sign that heat is melting this precautionary coating. To avoid a fire, switch off your furnace as soon as possible and have it inspected out by an HVAC technician.
  2. Gas or rotten eggs. Gas companies include sulfur in natural gas to alert you when there’s a leak. If your furnace smells like gas or rotten eggs, turn it off right away, leave your home and call 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 flourishing in your ductwork. We recommend having your ductwork checked and cleaned if necessary.
