Have you recently had a new furnace installed 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 ignore.

Why Your New Furnace Smells

There are two factors why a new furnace might smell.

Protective Finish

Your furnace has a special coating on specific parts to keep them from rusting. This may include the heat exchanger, which safely exhausts gases like 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 normal and the smell should dissipate the more your furnace runs.

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 concerns.

Dust

Dust collects inside your furnace when it’s idle 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 disappear within a few minutes.

One way you can lessen or prevent this smell is by having furnace maintenance done each 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 time of year.

3 Other Furnace Smells You Shouldn’t Dismiss

While it’s less common for a new system to need furnace repair, it happens. Here are three other smells 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 difficulties. Electrical wiring is coated in plastic to prevent shocks, and this smell is an indication that heat is melting this preventive coating. To hinder a fire, shut 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 warn you when there’s a problem. If your furnace smells like gas or rotten eggs, shut it off right away, get out of 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 flourishing in your ductwork. We advise having your ductwork checked and cleaned if required.
