Have you recently had a new furnace installed and are now noticing a strange smell? You’re not alone, because many other homeowners also experience this at first. Let’s review what’s causing this smell, and when you can anticipate 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 Coating

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

When your furnace starts for the first couple of times, the coating may give off a burning smell. This is typical and the smell should go away the more your furnace heats.

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

Dust

Dust builds inside your furnace when it’s idle 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 lessen or prevent this smell is by having furnace maintenance done every single year. This is required to keep your valuable manufacturer’s warranty good, 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 need furnace repair, it can happen. 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 problem. Electrical wiring is protected in plastic to avoid shocks, and this smell is a sign that heat is melting this preventive coating. To hinder a fire, shut off your furnace right away and have it examined out by an HVAC technician.
  2. Gas or rotten eggs. Gas companies add sulfur to natural gas to warn you when there’s a leakage. If your furnace smells like gas or rotten eggs, shut it off as soon as possible, evacuate your home and contact 911. Exposure to natural gas can make you ill, 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 inspected and cleaned if required.
