Have you recently had a new furnace set up and are now having an unusual smell? You’re not alone, because a lot of other homeowners also have this happen at first. Let’s review what’s leading to this smell, and when you can anticipate it to subside, 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 stink.

Protective Finishing

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 produced during the heating process.

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

Dust

Dust accumulates inside your furnace when it’s off in warm weather. That dust will burn off when you switch on your furnace in the fall, making 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 valid, plus it keeps your furnace clean and ensures it will run perfectly 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 can happen. Here are three other scents you should look 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 prevent shocks, and this smell is an indication that heat is melting this protective coating. To prevent a fire, turn off your furnace immediately and have it checked out by an HVAC technician.
  2. Gas or rotten eggs. Gas companies add sulfur to natural gas to signal you when there’s a leak. If your furnace smells like gas or rotten eggs, shut it off right away, leave your home and dial 911. Exposure to natural gas can make you unwell, 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 checked and cleaned if required.
