Have you recently had a new furnace installed and are now experiencing a weird smell? You’re not alone, because plenty of other homeowners also experience this at first. Let’s review what’s leading to this smell, and when you can anticipate it to disappear, as well as three other furnace smells you shouldn’t disregard.

Why Your New Furnace Smells

There are two reasons why a new furnace might reek.

Protective Coating

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

When your furnace runs for the first couple of times, the coating may release a burning smell. This is typical and the smell should go away 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 lingers 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 subside within a few minutes.

One way you can reduce or prevent this smell is by having furnace maintenance done every year. This is necessary to keep your valuable manufacturer’s warranty valid, plus it keeps your furnace clean and ensures it will run properly during the upcoming heating period.

3 Other Furnace Smells You Shouldn’t Disregard

While it’s less common for a new system to necessitate furnace repair, it can happen. Here are three other scents 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 prevent shocks, and this smell is a signal that heat is melting this protective coating. To avoid 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 warn you when there’s a leakage. If your furnace smells like gas or rotten eggs, turn it off as soon as possible, get out of your home and call 911. Exposure to natural gas can make you sick, plus it’s extremely 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 inspected and cleaned if required.
