Have you recently had a new furnace installed and are now having an unusual smell? You’re not alone, because many other homeowners also have this happen at first. Let’s review what’s leading to this smell, and when you can expect it to go away, as well as three other furnace smells you shouldn’t disregard.
Why Your New Furnace Smells
There are two factors why a new furnace might smell.
Your furnace has a special application on some parts to keep them from rusting. This may include the heat exchanger, which safely exhausts gases such as 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 operates.
To be on the safe side, you’ll want to contact a heating and cooling company if the smell persists. A burning smell that remains can mean the motor has overheated or there’s an electrical problem, among other concerns.
Dust builds inside your furnace when it’s not running in the spring and summer. That dust will burn off when you turn on your furnace in the fall, making a burning smell. This smell should subside within a few minutes.
One way you can decrease or prevent this smell is by having furnace maintenance done every year. This is required to keep your valuable manufacturer’s warranty applicable, plus it keeps your furnace clean and ensures it will run smoothly during the upcoming heating period.
3 Other Furnace Smells You Shouldn’t Disregard
While it’s less common for a new system to necessitate furnace repair, it happens. Here are three other smells 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 covered in plastic to protect against shocks, and this smell is a sign that heat is melting this protective coating. To hinder a fire, shut off your furnace right away 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 problem. If your furnace smells like gas or rotten eggs, turn it off immediately, leave your home and contact 911. Exposure to natural gas can make you ill, plus it’s extremely flammable and explosive.
- 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 necessary.
