Have you recently had a new furnace set up 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 anticipate it to subside, 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 smell.
Your furnace has a special application on specific parts to keep them from rusting. This may include the heat exchanger, which safely exhausts gases like carbon monoxide naturally created during the heating process.
When your furnace runs for the first couple of times, the coating may release a burning smell. This is typical 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 lingers. A burning smell that lingers can mean the motor is too hot or there’s an electrical problem, among other issues.
Dust builds inside your furnace when it’s idle in the spring and summer. That dust will burn off when you flip on your furnace in the fall, producing a burning smell. This smell should disappear within a few minutes.
One way you can decrease or prevent this smell is by having furnace maintenance done every year. This is necessary to keep your valuable manufacturer’s warranty good, plus it keeps your furnace clean and ensures it will run properly during the upcoming heating season.
3 Other Furnace Smells You Shouldn’t Dismiss
While it’s less common for a new system to necessitate furnace repair, it can happen. 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 difficulties. Electrical wiring is coated in plastic to avoid shocks, and this smell is a sign that heat is melting this preventive coating. To prevent a fire, switch off your furnace right away 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 as soon as possible, evacuate your home and call 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 advise having your ductwork inspected and cleaned if required.
