Have you recently had a new furnace put in and are now noticing 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 look forward to it to go away, as well as three other furnace smells you shouldn’t neglect.

Why Your New Furnace Smells

There are two factors why a new furnace might smell.

Protective Coating

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

When your furnace operates for the first couple of times, the coating may release 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 persists. A burning smell that sticks around can mean the motor has overheated or there’s an electrical problem, among other problems.

Dust

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

One way you can lessen or prevent this smell is by having furnace maintenance done each year. This is necessary 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 Disregard

While it’s less common for a new system to necessitate furnace repair, it can happen. 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 problem. Electrical wiring is coated in plastic to avoid shocks, and this smell is a signal that heat is melting this protective coating. To prevent a fire, switch off your furnace immediately and have it inspected out by an HVAC technician.
  2. Gas or rotten eggs. Gas companies include sulfur in natural gas to alert you when there’s a leak. If your furnace smells like gas or rotten eggs, shut it off as soon as possible, leave your home and dial 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 growing in your ductwork. We suggest having your ductwork examined and cleaned if necessary.
