Have you recently had a new furnace put in and are now noticing an unusual smell? You’re not alone, because a lot of other homeowners also experience this at first. Let’s review what’s causing this smell, and when you can expect it to disappear, 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 reek.

Protective Finish

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

When your furnace runs for the first couple of times, the coating may give off a burning smell. This is standard and the smell should disperse 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 sticks around can mean the motor is too hot or there’s an electrical problem, among other concerns.

Dust

Dust collects inside your furnace when it’s not running in the summer. That dust will burn off when you flip on your furnace in the fall, creating a burning smell. This smell should disappear within a few minutes.

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

3 Other Furnace Smells You Shouldn’t Disregard

While it’s less common for a new system to necessitate furnace repair, it can happen. 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 difficulties. Electrical wiring is protected in plastic to avoid shocks, and this smell is a sign 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 include sulfur in natural gas to alert you when there’s a leak. If your furnace smells like gas or rotten eggs, shut it off right away, evacuate your home and call 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 flourishing in your ductwork. We suggest having your ductwork inspected and cleaned if needed.
