Have you recently had a new furnace set up 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 creating this smell, and when you can expect it to subside, as well as three other furnace smells you shouldn’t ignore.

Why Your New Furnace Smells

There are two reasons why a new furnace might stink.

Protective Coating

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

When your furnace runs for the first couple of times, the coating may give off a burning smell. This is normal and the smell should go away the more your furnace runs.

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

Dust

Dust collects inside your furnace when it’s off in warm weather. That dust will burn off when you switch on your furnace in the fall, creating a burning smell. This smell should disappear within a few minutes.

One way you can lessen 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 properly 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 happens. 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 avoid shocks, and this smell is a sign that heat is melting this protective coating. To prevent a fire, shut off your furnace right away and have it examined out by an HVAC technician.
  2. Gas or rotten eggs. Gas companies include sulfur in natural gas to signal you when there’s a problem. If your furnace smells like gas or rotten eggs, shut it off right away, evacuate your home and call 911. Exposure to natural gas can make you ill, plus it’s extremely 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 necessary.
