Have you recently had a new furnace installed and are now noticing a weird smell? You’re not alone, because many other homeowners also experience this at first. Let’s review what’s leading to this smell, and when you can look forward to it to go away, as well as three other furnace smells you shouldn’t disregard.
Why Your New Furnace Smells
There are two reasons why a new furnace might reek.
Your furnace has a special finish on specific parts to keep them from rusting. This may include the heat exchanger, which safely exhausts gases including carbon monoxide naturally made during the heating process.
When your furnace operates for the first couple of times, the coating may release a burning smell. This is typical and the smell should go away the more your furnace runs.
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 has overheated or there’s an electrical problem, among other problems.
Dust builds inside your furnace when it’s idle in the summer. That dust will burn off when you flip 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 single year. This is required to keep your valuable manufacturer’s warranty valid, plus it keeps your furnace clean and ensures it will run perfectly during the upcoming heating time of year.
3 Other Furnace Smells You Shouldn’t Disregard
While it’s less common for a new system to need furnace repair, it can happen. Here are three other odors 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 problem. Electrical wiring is covered in plastic to prevent shocks, and this smell is a signal that heat is melting this precautionary coating. To avoid a fire, turn off your furnace as soon as possible and have it checked out by an HVAC technician.
- Gas or rotten eggs. Gas companies include sulfur in natural gas to warn you when there’s a leakage. If your furnace smells like gas or rotten eggs, turn it off right away, leave 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 developing in your ductwork. We advise having your ductwork inspected and cleaned if necessary.
