Have you recently had a new furnace set up and are now having an unusual smell? You’re not alone, because a lot of other homeowners also have this happen at first. Let’s review what’s creating this smell, and when you can look forward to 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 reek.

Protective Finishing

Your furnace has a special application on some 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 operates for the first couple of times, the coating may give off a burning smell. This is standard and the smell should disperse the more your furnace runs.

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

Dust

Dust builds inside your furnace when it’s off in warm weather. That dust will burn off when you flip 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 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 season.

3 Other Furnace Smells You Shouldn’t Disregard

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 problem. Electrical wiring is protected in plastic to avoid shocks, and this smell is a sign that heat is melting this preventive coating. To hinder a fire, switch off your furnace right away 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, turn it off immediately, get out of your home and contact 911. Exposure to natural gas can make you unwell, 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 suggest having your ductwork inspected and cleaned if necessary.
