Have you recently had a new furnace set up and are now noticing a strange smell? You’re not alone, because plenty of other homeowners also experience this 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 factors why a new furnace might smell.

Protective Finishing

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

When your furnace starts for the first couple of times, the coating may emit a burning smell. This is normal and the smell should dissipate the more your furnace heats.

To be on the safe side, you’ll want to call 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 not running 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 each year. This is necessary to keep your valuable manufacturer’s warranty good, plus it keeps your furnace clean and ensures it will run properly during the upcoming heating season.

3 Other Furnace Smells You Shouldn’t Ignore

While it’s less common for a new system to require furnace repair, it happens. Here are three other scents 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 problem. Electrical wiring is protected in plastic to avoid shocks, and this smell is an indication that heat is melting this precautionary coating. To hinder a fire, switch off your furnace immediately and have it examined out by an HVAC technician.
  2. Gas or rotten eggs. Gas companies include sulfur in natural gas to alert you when there’s a problem. If your furnace smells like gas or rotten eggs, shut it off as soon as possible, leave 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.
