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

Your furnace has a special finish on some parts to keep them from rusting. This may include the heat exchanger, which safely gets rid of gases like carbon monoxide naturally produced 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 connect with a heating and cooling company if the smell lingers. A burning smell that remains 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, producing a burning smell. This smell should disappear within a few minutes.

One way you can lessen or prevent this smell is by having furnace maintenance done every single year. This is necessary to keep your valuable manufacturer’s warranty applicable, plus it keeps your furnace clean and ensures it will run perfectly 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 watch 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 avoid shocks, and this smell is a signal that heat is melting this protective coating. To prevent a fire, switch off your furnace right away and have it inspected 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, turn it off right away, evacuate your home and contact 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 flourishing in your ductwork. We suggest having your ductwork inspected and cleaned if required.
