Have you recently had a new furnace put in and are now experiencing a strange smell? You’re not alone, because plenty of other homeowners also have this happen at first. Let’s review what’s creating this smell, and when you can look forward to it to subside, 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 stink.

Protective Finish

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

When your furnace starts for the first couple of times, the coating may give off 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 connect with a heating and cooling company if the smell lingers. A burning smell that remains can mean the motor has overheated or there’s an electrical problem, among other issues.

Dust

Dust builds inside your furnace when it’s off in the spring and summer. That dust will burn off when you turn on your furnace in the fall, making a burning smell. This smell should subside 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 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 can happen. 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 difficulties. Electrical wiring is coated in plastic to protect against shocks, and this smell is a sign 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 add sulfur to natural gas to alert you when there’s a leakage. 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 sick, 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.
