Have you recently had a new furnace put in and are now experiencing an unusual smell? You’re not alone, because plenty of other homeowners also experience this 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 disregard.

Why Your New Furnace Smells

There are two reasons 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 gets rid of gases such as carbon monoxide naturally made during the heating process.

When your furnace starts for the first couple of times, the coating may release a burning smell. This is standard 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 continues. A burning smell that lingers can mean the motor has overheated or there’s an electrical problem, among other concerns.

Dust

Dust collects inside your furnace when it’s not running in warm weather. That dust will burn off when you switch on your furnace in the fall, making a burning smell. This smell should disappear within a few minutes.

One way you can lessen or prevent this smell is by having furnace maintenance done each year. This is required 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 Dismiss

While it’s less common for a new system to require 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 issue. Electrical wiring is protected in plastic to avoid shocks, and this smell is a sign that heat is melting this protective coating. To hinder a fire, switch 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 alert you when there’s a problem. If your furnace smells like gas or rotten eggs, shut it off immediately, get out of 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 recommend having your ductwork examined and cleaned if needed.
