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 factors why a new furnace might smell.

Protective Finishing

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

When your furnace starts for the first couple of times, the coating may release a burning smell. This is typical and the smell should dissipate 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 lingers can mean the motor has overheated or there’s an electrical problem, among other problems.

Dust

Dust builds inside your furnace when it’s not running in warm weather. That dust will burn off when you turn 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 needed to keep your valuable manufacturer’s warranty applicable, plus it keeps your furnace clean and ensures it will run properly 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 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 problem. Electrical wiring is coated in plastic to avoid shocks, and this smell is a signal that heat is melting this precautionary coating. To hinder a fire, shut 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 signal you when there’s a problem. If your furnace smells like gas or rotten eggs, turn it off right away, get out of your home and contact 911. Exposure to natural gas can make you sick, plus it’s very flammable and explosive.
  3. Musty. If your furnace smells musty, you might have mold and mildew growing in your ductwork. We advise having your ductwork inspected and cleaned if required.
