Have you recently had a new furnace put in and are now having a strange smell? You’re not alone, because a lot of other homeowners also have this happen 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 Coating

Your furnace has a special application on certain parts to keep them from rusting. This may include the heat exchanger, which safely exhausts gases like carbon monoxide naturally created 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 go away the more your furnace heats.

To be on the safe side, you’ll want to call a heating and cooling company if the smell persists. A burning smell that remains can mean the motor is too hot or there’s an electrical problem, among other issues.

Dust

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

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

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 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 protect against shocks, and this smell is an indication that heat is melting this preventive coating. To hinder 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 alert you when there’s a problem. If your furnace smells like gas or rotten eggs, shut 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 checked and cleaned if needed.
