Have you recently had a new furnace set up and are now noticing an unusual smell? You’re not alone, because many other homeowners also experience this at first. Let’s review what’s causing this smell, and when you can look forward to it to subside, 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 reek.

Protective Finishing

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

To be on the safe side, you’ll want to call 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 not running in warm weather. That dust will burn off when you flip on your furnace in the fall, creating 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 year. This is needed to keep your valuable manufacturer’s warranty applicable, plus it keeps your furnace clean and ensures it will run perfectly 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 difficulties. Electrical wiring is covered in plastic to prevent shocks, and this smell is a signal that heat is melting this preventive coating. To prevent a fire, turn 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 warn you when there’s a problem. If your furnace smells like gas or rotten eggs, turn it off as soon as possible, get out of your home and contact 911. Exposure to natural gas can make you ill, plus it’s extremely flammable and explosive.
  3. Musty. If your furnace smells musty, you might have mold and mildew developing in your ductwork. We advise having your ductwork examined and cleaned if required.
