Have you recently had a new furnace set up 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 leading to this smell, and when you can expect it to go away, 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 Coating

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

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

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

Dust

Dust collects inside your furnace when it’s not running in the spring and summer. That dust will burn off when you switch on your furnace in the fall, creating 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 each year. This is necessary to keep your valuable manufacturer’s warranty good, 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 need furnace repair, it can happen. Here are three other odors 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 difficulties. Electrical wiring is coated in plastic to protect against shocks, and this smell is a sign that heat is melting this precautionary coating. To hinder a fire, switch off your furnace right away and have it checked out by an HVAC technician.
  2. Gas or rotten eggs. Gas companies add sulfur to natural gas to signal you when there’s a problem. If your furnace smells like gas or rotten eggs, shut it off right away, get out of your home and dial 911. Exposure to natural gas can make you sick, plus it’s extremely flammable and explosive.
  3. Musty. If your furnace smells musty, you might have mold and mildew developing in your ductwork. We advise having your ductwork examined and cleaned if required.
