Have you recently had a new furnace put in and are now experiencing a strange smell? You’re not alone, because many other homeowners also have this happen 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 neglect.

Why Your New Furnace Smells

There are two reasons why a new furnace might reek.

Protective Coating

Your furnace has a special coating on certain parts to keep them from rusting. This may include the heat exchanger, which safely removes gases including carbon monoxide naturally produced during the heating process.

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

To be on the safe side, you’ll want to call 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 issues.

Dust

Dust builds 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, producing a burning smell. This smell should subside within a few minutes.

One way you can reduce or prevent this smell is by having furnace maintenance done every single year. This is needed to keep your valuable manufacturer’s warranty applicable, plus it keeps your furnace clean and ensures it will run perfectly during the upcoming heating season.

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 keep an eye 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 coated in plastic to prevent shocks, and this smell is an indication that heat is melting this preventive coating. To prevent a fire, turn off your furnace right away and have it checked out by an HVAC technician.
  2. Gas or rotten eggs. Gas companies include sulfur in natural gas to signal you when there’s a leak. If your furnace smells like gas or rotten eggs, turn it off right away, evacuate 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 developing in your ductwork. We recommend having your ductwork examined and cleaned if needed.
