Have you recently had a new furnace installed and are now experiencing a strange 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 look forward to it to go away, 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 smell.

Protective Finish

Your furnace has a special application on certain parts to keep them from rusting. This may include the heat exchanger, which safely gets rid of gases like 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 normal and the smell should disperse the more your furnace operates.

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

Dust

Dust collects inside your furnace when it’s not running in the summer. That dust will burn off when you switch on your furnace in the fall, creating 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 necessary 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 Ignore

While it’s less common for a new system to require 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 prevent shocks, and this smell is a signal that heat is melting this precautionary coating. To avoid a fire, turn off your furnace immediately and have it inspected out by an HVAC technician.
  2. Gas or rotten eggs. Gas companies include sulfur in natural gas to alert you when there’s a problem. If your furnace smells like gas or rotten eggs, turn it off right away, evacuate your home and call 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 developing in your ductwork. We recommend having your ductwork examined and cleaned if required.
