Have you recently had a new furnace installed and are now noticing a weird smell? You’re not alone, because a lot 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 ignore.

Why Your New Furnace Smells

There are two factors why a new furnace might reek.

Protective Finishing

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

When your furnace runs 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 operates.

To be on the safe side, you’ll want to contact a heating and cooling company if the smell lingers. A burning smell that lingers can mean the motor is too hot or there’s an electrical problem, among other problems.

Dust

Dust accumulates inside your furnace when it’s off in the summer. That dust will burn off when you switch on your furnace in the fall, producing a burning smell. This smell should subside within a few minutes.

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

3 Other Furnace Smells You Shouldn’t Dismiss

While it’s less common for a new system to require furnace repair, it happens. Here are three other odors 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 protect against shocks, and this smell is a signal that heat is melting this precautionary coating. To hinder a fire, switch off your furnace as soon as possible and have it examined out by an HVAC technician.
  2. Gas or rotten eggs. Gas companies add sulfur to natural gas to warn you when there’s a problem. If your furnace smells like gas or rotten eggs, shut it off immediately, leave your home and call 911. Exposure to natural gas can make you sick, 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 recommend having your ductwork examined and cleaned if necessary.
