Have you recently had a new furnace put in and are now having an unusual smell? You’re not alone, because plenty of other homeowners also experience this at first. Let’s review what’s causing 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 stink.

Protective Finishing

Your furnace has a special application 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 give off a burning smell. This is standard and the smell should dissipate the more your furnace heats.

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 remains can mean the motor has overheated or there’s an electrical problem, among other concerns.

Dust

Dust collects 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, producing a burning smell. This smell should disappear within a few minutes.

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

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 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 difficulties. Electrical wiring is covered in plastic to prevent shocks, and this smell is an indication that heat is melting this precautionary coating. To hinder a fire, shut off your furnace right away 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 leak. If your furnace smells like gas or rotten eggs, shut it off right away, get out of your home and call 911. Exposure to natural gas can make you unwell, plus it’s extremely flammable and explosive.
  3. Musty. If your furnace smells musty, you might have mold and mildew flourishing in your ductwork. We suggest having your ductwork checked and cleaned if necessary.
