Have you recently had a new furnace installed 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 leading to this smell, and when you can anticipate it to disappear, as well as three other furnace smells you shouldn’t ignore.

Why Your New Furnace Smells

There are two reasons 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 exhausts gases such as carbon monoxide naturally created during the heating process.

When your furnace starts for the first couple of times, the coating may release a burning smell. This is normal and the smell should go away the more your furnace operates.

To be on the safe side, you’ll want to call a heating and cooling company if the smell persists. A burning smell that lingers can mean the motor has overheated or there’s an electrical problem, among other problems.

Dust

Dust accumulates inside your furnace when it’s not running in the summer. That dust will burn off when you flip on your furnace in the fall, producing 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 each year. This is needed to keep your valuable manufacturer’s warranty good, plus it keeps your furnace clean and ensures it will run smoothly during the upcoming heating time of year.

3 Other Furnace Smells You Shouldn’t Ignore

While it’s less common for a new system to necessitate furnace repair, it happens. 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 difficulties. Electrical wiring is coated in plastic to protect against shocks, and this smell is a signal that heat is melting this protective coating. To hinder a fire, switch off your furnace right away 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 leak. If your furnace smells like gas or rotten eggs, turn it off immediately, leave 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 growing in your ductwork. We advise having your ductwork checked and cleaned if necessary.
