Have you recently had a new furnace set up and are now having a weird smell? You’re not alone, because a lot of other homeowners also have this happen at first. Let’s review what’s leading to this smell, and when you can expect it to disappear, as well as three other furnace smells you shouldn’t neglect.

Why Your New Furnace Smells

There are two factors why a new furnace might smell.

Protective Finish

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 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 standard and the smell should go away 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 lingers. A burning smell that lingers can mean the motor is too hot or there’s an electrical problem, among other problems.

Dust

Dust collects inside your furnace when it’s off in the summer. That dust will burn off when you turn 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 each year. This is necessary to keep your valuable manufacturer’s warranty valid, plus it keeps your furnace clean and ensures it will run smoothly 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 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 problem. Electrical wiring is covered in plastic to avoid shocks, and this smell is an indication that heat is melting this precautionary coating. To avoid a fire, switch off your furnace as soon as possible and have it checked out by an HVAC technician.
  2. Gas or rotten eggs. Gas companies include sulfur in natural gas to warn you when there’s a leak. If your furnace smells like gas or rotten eggs, shut it off immediately, leave your home and call 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 recommend having your ductwork checked and cleaned if required.
