Have you recently had a new furnace set up and are now experiencing a strange smell? You’re not alone, because many other homeowners also have this happen at first. Let’s review what’s causing this smell, and when you can look forward to 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 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 exhausts gases such as carbon monoxide naturally created 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 go away the more your furnace operates.

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 accumulates inside your furnace when it’s off in the summer. That dust will burn off when you turn on your furnace in the fall, producing a burning smell. This smell should go away within a few minutes.

One way you can decrease or prevent this smell is by having furnace maintenance done every single year. This is needed to keep your valuable manufacturer’s warranty valid, plus it keeps your furnace clean and ensures it will run smoothly during the upcoming heating period.

3 Other Furnace Smells You Shouldn’t Ignore

While it’s less common for a new system to necessitate furnace repair, it can happen. Here are three other odors 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 problem. Electrical wiring is covered in plastic to avoid shocks, and this smell is a sign that heat is melting this precautionary coating. To hinder a fire, switch off your furnace as soon as possible and have it examined out by an HVAC technician.
  2. Gas or rotten eggs. Gas companies include sulfur in natural gas to warn you when there’s a leakage. If your furnace smells like gas or rotten eggs, shut it off immediately, leave your home and dial 911. Exposure to natural gas can make you sick, plus it’s very flammable and explosive.
  3. Musty. If your furnace smells musty, you might have mold and mildew growing in your ductwork. We advise having your ductwork examined and cleaned if required.
