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 go away, as well as three other furnace smells you shouldn’t disregard.
Why Your New Furnace Smells
There are two explanations why a new furnace might reek.
Your furnace has a special application on certain parts to keep them from rusting. This may include the heat exchanger, which safely exhausts gases including 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 standard and the smell should disperse the more your furnace operates.
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 sticks around can mean the motor is too hot or there’s an electrical problem, among other concerns.
Dust accumulates inside your furnace when it’s not running in warm weather. That dust will burn off when you turn on your furnace in the fall, making a burning smell. This smell should go away 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 applicable, plus it keeps your furnace clean and ensures it will run perfectly 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 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 an indication that heat is melting this preventive coating. To avoid a fire, turn off your furnace right away and have it examined out by an HVAC technician.
- Gas or rotten eggs. Gas companies include sulfur in natural gas to alert you when there’s a problem. If your furnace smells like gas or rotten eggs, shut it off as soon as possible, evacuate your home and contact 911. Exposure to natural gas can make you unwell, 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 required.
