Have you recently had a new furnace put in and are now having a strange 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 anticipate it to disappear, as well as three other furnace smells you shouldn’t neglect.

Why Your New Furnace Smells

There are two factors why a new furnace might reek.

Protective Finishing

Your furnace has a special coating on specific parts to keep them from rusting. This may include the heat exchanger, which safely removes gases like carbon monoxide naturally made during the heating process.

When your furnace runs for the first couple of times, the coating may give off a burning smell. This is normal and the smell should disperse the more your furnace runs.

To be on the safe side, you’ll want to call 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 problems.

Dust

Dust collects inside your furnace when it’s off in the spring and 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 lessen or prevent this smell is by having furnace maintenance done every year. This is needed to keep your valuable manufacturer’s warranty valid, plus it keeps your furnace clean and ensures it will run perfectly during the upcoming heating time of year.

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 smells you should watch for and what they might mean.

  1. Burning plastic or rubber. If your furnace smells like burning plastic, you might have an electrical issue. Electrical wiring is covered in plastic to prevent shocks, and this smell is a sign that heat is melting this precautionary coating. To hinder a fire, shut off your furnace immediately and have it inspected out by an HVAC technician.
  2. Gas or rotten eggs. Gas companies add sulfur to natural gas to signal you when there’s a leak. If your furnace smells like gas or rotten eggs, shut it off right away, evacuate your home and dial 911. Exposure to natural gas can make you ill, 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 needed.
