Have you recently had a new furnace put in and are now noticing a weird smell? You’re not alone, because plenty of other homeowners also have this happen at first. Let’s review what’s creating this smell, and when you can expect it to go away, 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 finish on specific parts to keep them from rusting. This may include the heat exchanger, which safely exhausts gases including carbon monoxide naturally made during the heating process.

When your furnace operates for the first couple of times, the coating may emit a burning smell. This is typical and the smell should disperse the more your furnace heats.

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

Dust

Dust accumulates 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, creating a burning smell. This smell should subside 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 properly during the upcoming heating time of year.

3 Other Furnace Smells You Shouldn’t Dismiss

While it’s less common for a new system to necessitate furnace repair, it happens. Here are three other scents you should look 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 covered in plastic to avoid shocks, and this smell is a signal that heat is melting this precautionary coating. To avoid a fire, shut off your furnace as soon as possible 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, shut it off as soon as possible, leave your home and dial 911. Exposure to natural gas can make you unwell, plus it’s very 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 inspected and cleaned if needed.
