Have you recently had a new furnace put in and are now experiencing a strange 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 look forward to it to go away, 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 smell.

Protective Finish

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

When your furnace operates for the first couple of times, the coating may emit a burning smell. This is standard and the smell should dissipate the more your furnace runs.

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

Dust

Dust collects inside your furnace when it’s not running in warm weather. That dust will burn off when you flip on your furnace in the fall, producing a burning smell. This smell should disappear within a few minutes.

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

3 Other Furnace Smells You Shouldn’t Ignore

While it’s less common for a new system to require furnace repair, it happens. Here are three other scents you should keep an eye 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 avoid shocks, and this smell is a signal that heat is melting this preventive coating. To prevent a fire, shut off your furnace right away 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 highly 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 inspected and cleaned if needed.
