Have you recently had a new furnace put in and are now noticing an unusual smell? You’re not alone, because many other homeowners also have this happen at first. Let’s review what’s leading to this smell, and when you can expect it to subside, as well as three other furnace smells you shouldn’t neglect.

Why Your New Furnace Smells

There are two explanations why a new furnace might smell.

Protective Coating

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

When your furnace starts for the first couple of times, the coating may emit a burning smell. This is standard and the smell should dissipate the more your furnace runs.

To be on the safe side, you’ll want to call 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 idle in the summer. That dust will burn off when you turn on your furnace in the fall, creating 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 every single 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 Dismiss

While it’s less common for a new system to need furnace repair, it happens. Here are three other scents 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 covered in plastic to protect against shocks, and this smell is a sign that heat is melting this protective coating. To avoid a fire, shut off your furnace right away and have it examined out by an HVAC technician.
  2. Gas or rotten eggs. Gas companies include sulfur in natural gas to warn you when there’s a leak. If your furnace smells like gas or rotten eggs, shut it off right away, leave your home and contact 911. Exposure to natural gas can make you ill, plus it’s very flammable and explosive.
  3. Musty. If your furnace smells musty, you might have mold and mildew flourishing in your ductwork. We recommend having your ductwork examined and cleaned if required.
