Have you recently had a new furnace installed and are now experiencing a weird smell? You’re not alone, because many other homeowners also experience this at first. Let’s review what’s creating this smell, and when you can anticipate it to subside, 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 Finish

Your furnace has a special application on certain parts to keep them from rusting. This may include the heat exchanger, which safely gets rid of gases like carbon monoxide naturally made during the heating process.

When your furnace starts 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 operates.

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

Dust

Dust accumulates inside your furnace when it’s idle in the spring and summer. That dust will burn off when you switch on your furnace in the fall, creating a burning smell. This smell should subside within a few minutes.

One way you can lessen or prevent this smell is by having furnace maintenance done every single 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 time of year.

3 Other Furnace Smells You Shouldn’t Dismiss

While it’s less common for a new system to require furnace repair, it happens. Here are three other scents you should look out 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 prevent shocks, and this smell is an indication that heat is melting this preventive coating. To hinder a fire, shut off your furnace immediately and have it checked out by an HVAC technician.
  2. Gas or rotten eggs. Gas companies add sulfur to natural gas to warn you when there’s a leak. If your furnace smells like gas or rotten eggs, shut it off as soon as possible, get out of your home and call 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 growing in your ductwork. We recommend having your ductwork checked and cleaned if needed.
