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

Why Your New Furnace Smells

There are two explanations why a new furnace might stink.

Protective Finishing

Your furnace has a special coating on some parts to keep them from rusting. This may include the heat exchanger, which safely exhausts gases like carbon monoxide naturally created during the heating process.

When your furnace runs for the first couple of times, the coating may emit 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 has overheated or there’s an electrical problem, among other issues.

Dust

Dust collects inside your furnace when it’s idle in the spring and summer. That dust will burn off when you flip on your furnace in the fall, making a burning smell. This smell should disappear within a few minutes.

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

3 Other Furnace Smells You Shouldn’t Disregard

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 difficulties. Electrical wiring is coated in plastic to prevent shocks, and this smell is a signal that heat is melting this protective coating. To avoid 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 alert you when there’s a leak. If your furnace smells like gas or rotten eggs, shut it off right away, leave your home and dial 911. Exposure to natural gas can make you ill, plus it’s extremely 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.
