Have you recently had a new furnace put in and are now having a strange 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 expect it to disappear, as well as three other furnace smells you shouldn’t neglect.

Why Your New Furnace Smells

There are two explanations why a new furnace might reek.

Protective Finishing

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 including carbon monoxide naturally created during the heating process.

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

To be on the safe side, you’ll want to contact 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 turn 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 necessary to keep your valuable manufacturer’s warranty good, plus it keeps your furnace clean and ensures it will run perfectly during the upcoming heating season.

3 Other Furnace Smells You Shouldn’t Ignore

While it’s less common for a new system to need furnace repair, it happens. Here are three other odors you should keep an eye out 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 protect against shocks, and this smell is a signal that heat is melting this precautionary coating. To prevent a fire, shut off your furnace as soon as possible and have it inspected out by an HVAC technician.
  2. Gas or rotten eggs. Gas companies add sulfur to natural gas to alert you when there’s a problem. 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 ill, plus it’s highly flammable and explosive.
  3. Musty. If your furnace smells musty, you might have mold and mildew developing in your ductwork. We recommend having your ductwork examined and cleaned if required.
