Have you recently had a new furnace put in and are now noticing an unusual smell? You’re not alone, because plenty of 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 disappear, 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 Finish

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

When your furnace starts for the first couple of times, the coating may give off a burning smell. This is typical and the smell should go away the more your furnace runs.

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

Dust

Dust collects inside your furnace when it’s not running in warm weather. That dust will burn off when you switch on your furnace in the fall, producing 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 every year. This is necessary 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 Ignore

While it’s less common for a new system to necessitate furnace repair, it can happen. Here are three other odors 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 a sign that heat is melting this protective coating. To prevent a fire, switch off your furnace right away 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 leakage. If your furnace smells like gas or rotten eggs, shut it off immediately, get out of your home and contact 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 checked and cleaned if necessary.
