Have you recently had a new furnace put in and are now having a weird smell? You’re not alone, because a lot of 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 reasons why a new furnace might reek.

Protective Finish

Your furnace has a special application on specific parts to keep them from rusting. This may include the heat exchanger, which safely gets rid of 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 standard and the smell should disperse 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 persists. A burning smell that lingers can mean the motor is too hot or there’s an electrical problem, among other problems.

Dust

Dust builds inside your furnace when it’s off in warm weather. That dust will burn off when you turn on your furnace in the fall, making a burning smell. This smell should go away within a few minutes.

One way you can lessen or prevent this smell is by having furnace maintenance done every single year. This is needed to keep your valuable manufacturer’s warranty good, plus it keeps your furnace clean and ensures it will run properly 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 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 protected in plastic to avoid shocks, and this smell is an indication that heat is melting this preventive coating. To hinder a fire, turn 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 signal you when there’s a leak. If your furnace smells like gas or rotten eggs, turn it off as soon as possible, evacuate your home and contact 911. Exposure to natural gas can make you sick, 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 suggest having your ductwork checked and cleaned if necessary.
