Have you recently had a new furnace installed and are now experiencing a strange smell? You’re not alone, because a lot of other homeowners also experience this at first. Let’s review what’s creating this smell, and when you can expect 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 smell.

Protective Finish

Your furnace has a special coating on certain parts to keep them from rusting. This may include the heat exchanger, which safely exhausts gases such as carbon monoxide naturally created during the heating process.

When your furnace runs 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 operates.

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

Dust

Dust collects inside your furnace when it’s idle in the spring and summer. That dust will burn off when you flip on your furnace in the fall, producing 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 each year. This is necessary to keep your valuable manufacturer’s warranty valid, 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 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 prevent shocks, and this smell is an indication that heat is melting this precautionary coating. To avoid a fire, turn off your furnace as soon as possible and have it inspected out by an HVAC technician.
  2. Gas or rotten eggs. Gas companies add sulfur to natural gas to warn you when there’s a leak. If your furnace smells like gas or rotten eggs, shut it off immediately, evacuate your home and call 911. Exposure to natural gas can make you unwell, 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 advise having your ductwork inspected and cleaned if required.
