Have you recently had a new furnace put in and are now having an unusual smell? You're not alone, because a lot of other homeowners also have this happen at first. Let’s review what’s creating this smell, and when you can expect 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 Coating
Your furnace has a special application on specific parts to keep them from rusting. This may include the heat exchanger, which safely removes gases including carbon monoxide naturally produced during the heating process.
When your furnace runs for the first couple of times, the coating may give off 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 connect with a heating and cooling company if the smell lingers. A burning smell that remains can mean the motor is too hot or there’s an electrical problem, among other problems.
Dust
Dust collects inside your furnace when it’s off in the summer. That dust will burn off when you turn on your furnace in the fall, producing a burning smell. This smell should subside within a few minutes.
One way you can lessen or prevent this smell is by having furnace maintenance done every year. This is needed to keep your valuable manufacturer’s warranty valid, 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 Ignore
While it’s less common for a new system to require furnace repair, it happens. Here are three other odors you should watch for and what they might mean.
- Burning plastic or rubber. If your furnace smells like burning plastic, you might have an electrical difficulties. Electrical wiring is protected in plastic to protect against shocks, and this smell is an indication that heat is melting this preventive coating. To avoid a fire, turn 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 warn you when there’s a problem. If your furnace smells like gas or rotten eggs, turn it off right away, leave your home and dial 911. Exposure to natural gas can make you ill, plus it’s very flammable and explosive.
- Musty. If your furnace smells musty, you might have mold and mildew growing in your ductwork. We recommend having your ductwork inspected and cleaned if needed.
