Have you recently had a new furnace put in and are now experiencing a weird 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 go away, 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 reek.

Protective Finishing

Your furnace has a special application on certain parts to keep them from rusting. This may include the heat exchanger, which safely removes 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 standard 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 problems.

Dust

Dust collects inside your furnace when it’s idle in warm weather. That dust will burn off when you flip on your furnace in the fall, producing a burning smell. This smell should go away within a few minutes.

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

3 Other Furnace Smells You Shouldn’t Ignore

While it’s less common for a new system to require furnace repair, it can happen. 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 protected in plastic to avoid shocks, and this smell is a sign that heat is melting this preventive coating. To hinder a fire, switch off your furnace as soon as possible and have it examined out by an HVAC technician.
  2. Gas or rotten eggs. Gas companies add sulfur to 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, evacuate 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 flourishing in your ductwork. We recommend having your ductwork examined and cleaned if necessary.
