Have you recently had a new furnace put in and are now noticing a weird smell? You’re not alone, because a lot of other homeowners also have this happen at first. Let’s review what’s causing 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 Finishing

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

To be on the safe side, you’ll want to connect with a heating and cooling company if the smell continues. A burning smell that lingers 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 idle in warm weather. That dust will burn off when you turn 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 every single year. This is required to keep your valuable manufacturer’s warranty good, plus it keeps your furnace clean and ensures it will run smoothly during the upcoming heating period.

3 Other Furnace Smells You Shouldn’t Dismiss

While it’s less common for a new system to need furnace repair, it can happen. Here are three other odors 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 issue. Electrical wiring is coated in plastic to avoid shocks, and this smell is a sign that heat is melting this preventive coating. To prevent a fire, switch off your furnace as soon as possible and have it inspected out by an HVAC technician.
  2. Gas or rotten eggs. Gas companies add sulfur to natural gas to warn you when there’s a leak. If your furnace smells like gas or rotten eggs, turn it off right away, evacuate your home and contact 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 advise having your ductwork examined and cleaned if needed.
