Have you recently had a new furnace set up and are now having an unusual smell? You’re not alone, because plenty of other homeowners also have this happen at first. Let’s review what’s leading to this smell, and when you can anticipate it to go away, as well as three other furnace smells you shouldn’t disregard.

Why Your New Furnace Smells

There are two explanations why a new furnace might reek.

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 such as carbon monoxide naturally created during the heating process.

When your furnace operates for the first couple of times, the coating may release a burning smell. This is normal and the smell should dissipate the more your furnace heats.

To be on the safe side, you’ll want to call a heating and cooling company if the smell lingers. A burning smell that lingers can mean the motor is too hot or there’s an electrical problem, among other issues.

Dust

Dust accumulates inside your furnace when it’s idle in warm weather. 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 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 Disregard

While it’s less common for a new system to need furnace repair, it happens. 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 coated in plastic to avoid shocks, and this smell is a signal that heat is melting this precautionary coating. To prevent a fire, turn off your furnace as soon as possible and have it checked out by an HVAC technician.
  2. Gas or rotten eggs. Gas companies include sulfur in natural gas to signal you when there’s a leakage. If your furnace smells like gas or rotten eggs, shut it off right away, leave your home and call 911. Exposure to natural gas can make you ill, plus it’s highly flammable and explosive.
  3. Musty. If your furnace smells musty, you might have mold and mildew developing in your ductwork. We advise having your ductwork inspected and cleaned if necessary.
