Have you recently had a new furnace set up and are now having a strange smell? You’re not alone, because plenty of other homeowners also have this happen at first. Let’s review what’s causing this smell, and when you can anticipate 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 stink.

Protective Finish

Your furnace has a special coating on specific 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 starts for the first couple of times, the coating may emit 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 contact 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 off in the summer. That dust will burn off when you switch on your furnace in the fall, making 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 year. This is necessary to keep your valuable manufacturer’s warranty good, plus it keeps your furnace clean and ensures it will run perfectly during the upcoming heating time of year.

3 Other Furnace Smells You Shouldn’t Ignore

While it’s less common for a new system to require 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 issue. Electrical wiring is covered in plastic to protect against shocks, and this smell is a signal that heat is melting this protective coating. To hinder a fire, switch off your furnace as soon as possible and have it examined 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, turn it off immediately, leave your home and call 911. Exposure to natural gas can make you sick, plus it’s extremely 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 checked and cleaned if required.
