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 expect 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.
Your furnace has a special application on specific parts to keep them from rusting. This may include the heat exchanger, which safely exhausts gases including 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 heats.
To be on the safe side, you’ll want to contact a heating and cooling company if the smell persists. A burning smell that sticks around can mean the motor is too hot or there’s an electrical problem, among other problems.
Dust accumulates inside your furnace when it’s idle in warm weather. 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 lessen or prevent this smell is by having furnace maintenance done every single year. This is needed to keep your valuable manufacturer’s warranty applicable, 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 Dismiss
While it’s less common for a new system to require furnace repair, it happens. Here are three other scents you should keep an eye out for and what they might mean.
- Burning plastic or rubber. If your furnace smells like burning plastic, you might have an electrical issue. Electrical wiring is protected in plastic to prevent shocks, and this smell is a sign that heat is melting this protective coating. To hinder a fire, shut off your furnace as soon as possible and have it examined out by an HVAC technician.
- Gas or rotten eggs. Gas companies add sulfur to natural gas to alert you when there’s a leak. If your furnace smells like gas or rotten eggs, turn it off right away, leave your home and call 911. Exposure to natural gas can make you ill, plus it’s highly flammable and explosive.
- Musty. If your furnace smells musty, you might have mold and mildew growing in your ductwork. We suggest having your ductwork examined and cleaned if required.
