Have you recently had a new furnace installed and are now having a weird 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 anticipate it to go away, as well as three other furnace smells you shouldn’t disregard.

Why Your New Furnace Smells

There are two explanations why a new furnace might reek.

Protective Finishing

Your furnace has a special coating on specific 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 starts for the first couple of times, the coating may emit a burning smell. This is typical and the smell should go away 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 lingers can mean the motor is too hot or there’s an electrical problem, among other issues.

Dust

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

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

3 Other Furnace Smells You Shouldn’t Dismiss

While it’s less common for a new system to necessitate furnace repair, it can happen. 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 issue. Electrical wiring is protected in plastic to protect against shocks, and this smell is a sign that heat is melting this protective coating. To prevent a fire, turn off your furnace immediately and have it checked out by an HVAC technician.
  2. Gas or rotten eggs. Gas companies include sulfur in natural gas to signal you when there’s a leak. If your furnace smells like gas or rotten eggs, turn it off as soon as possible, get out of your home and dial 911. Exposure to natural gas can make you sick, 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 suggest having your ductwork examined and cleaned if required.
