Have you recently had a new furnace set up and are now experiencing a strange smell? You’re not alone, because many 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 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 smell.

Protective Coating

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

When your furnace operates for the first couple of times, the coating may give off a burning smell. This is typical and the smell should dissipate 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 lingers. A burning smell that lingers can mean the motor has overheated or there’s an electrical problem, among other issues.

Dust

Dust collects inside your furnace when it’s not running in the spring and summer. That dust will burn off when you turn on your furnace in the fall, producing a burning smell. This smell should go away within a few minutes.

One way you can reduce or prevent this smell is by having furnace maintenance done every single year. This is required to keep your valuable manufacturer’s warranty applicable, plus it keeps your furnace clean and ensures it will run properly 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 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 issue. Electrical wiring is covered in plastic to avoid shocks, and this smell is a signal that heat is melting this precautionary coating. To avoid a fire, turn off your furnace immediately and have it examined 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 as soon as possible, get out of your home and call 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 flourishing in your ductwork. We suggest having your ductwork checked and cleaned if needed.
