Have you recently had a new furnace set up 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 creating this smell, and when you can look forward to it to disappear, 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 smell.

Protective Finish

Your furnace has a special finish on some parts to keep them from rusting. This may include the heat exchanger, which safely removes gases including 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 standard and the smell should dissipate the more your furnace runs.

To be on the safe side, you’ll want to contact a heating and cooling company if the smell persists. A burning smell that sticks around can mean the motor has overheated or there’s an electrical problem, among other issues.

Dust

Dust builds inside your furnace when it’s off in the spring and summer. That dust will burn off when you flip on your furnace in the fall, making 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 year. This is needed to keep your valuable manufacturer’s warranty applicable, plus it keeps your furnace clean and ensures it will run perfectly 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 can happen. 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 coated in plastic to avoid shocks, and this smell is a sign that heat is melting this precautionary coating. To prevent a fire, turn off your furnace immediately and have it examined out by an HVAC technician.
  2. Gas or rotten eggs. Gas companies add sulfur to natural gas to alert 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 dial 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 recommend having your ductwork inspected and cleaned if necessary.
