Have you recently had a new furnace put in and are now noticing a strange smell? You’re not alone, because plenty of other homeowners also experience this at first. Let’s review what’s creating this smell, and when you can anticipate 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 finish on specific parts to keep them from rusting. This may include the heat exchanger, which safely exhausts gases such as carbon monoxide naturally created during the heating process.
When your furnace operates for the first couple of times, the coating may emit 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 call a heating and cooling company if the smell continues. A burning smell that sticks around can mean the motor is too hot or there’s an electrical problem, among other problems.
Dust collects inside your furnace when it’s off in the spring and summer. 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 year. This is required to keep your valuable manufacturer’s warranty valid, plus it keeps your furnace clean and ensures it will run smoothly during the upcoming heating season.
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 odors you should look out 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 prevent shocks, and this smell is an indication that heat is melting this preventive coating. To avoid a fire, shut off your furnace immediately and have it inspected out by an HVAC technician.
- Gas or rotten eggs. Gas companies include sulfur in natural gas to warn you when there’s a leak. If your furnace smells like gas or rotten eggs, turn it off right away, evacuate your home and contact 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 developing in your ductwork. We recommend having your ductwork examined and cleaned if required.
