Have you recently had a new furnace installed and are now having a weird smell? You’re not alone, because many other homeowners also have this happen at first. Let’s review what’s creating this smell, and when you can expect it to go away, as well as three other furnace smells you shouldn’t neglect.

Why Your New Furnace Smells

There are two explanations why a new furnace might smell.

Protective Finish

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

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

To be on the safe side, you’ll want to connect with 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 concerns.

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 go away within a few minutes.

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

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 smells 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 avoid shocks, and this smell is a sign that heat is melting this protective coating. To hinder a fire, switch 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 signal you when there’s a problem. If your furnace smells like gas or rotten eggs, turn it off as soon as possible, leave your home and call 911. Exposure to natural gas can make you unwell, 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 suggest having your ductwork examined and cleaned if needed.
