Have you recently had a new furnace put in and are now experiencing an unusual smell? You’re not alone, because plenty 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 disappear, as well as three other furnace smells you shouldn’t neglect.

Why Your New Furnace Smells

There are two factors why a new furnace might stink.

Protective Finish

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

When your furnace operates for the first couple of times, the coating may emit a burning smell. This is typical and the smell should go away 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 persists. A burning smell that lingers can mean the motor has overheated or there’s an electrical problem, among other problems.

Dust

Dust collects 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, creating 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 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 require furnace repair, it can happen. Here are three other scents you should watch 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 protected in plastic to prevent shocks, and this smell is a signal that heat is melting this precautionary coating. To prevent a fire, turn off your furnace as soon as possible and have it examined out by an HVAC technician.
  2. Gas or rotten eggs. Gas companies include sulfur in natural gas to warn 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 sick, 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 checked and cleaned if needed.
