Have you recently had a new furnace put in and are now having a weird smell? You’re not alone, because plenty of other homeowners also have this happen at first. Let’s review what’s causing this smell, and when you can look forward to it to disappear, as well as three other furnace smells you shouldn’t ignore.
Why Your New Furnace Smells
There are two reasons why a new furnace might stink.
Your furnace has a special coating on certain parts to keep them from rusting. This may include the heat exchanger, which safely removes gases including carbon monoxide naturally created during the heating process.
When your furnace operates for the first couple of times, the coating may give off a burning smell. This is typical 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 continues. A burning smell that remains can mean the motor is too hot or there’s an electrical problem, among other concerns.
Dust accumulates inside your furnace when it’s off in the summer. That dust will burn off when you switch on your furnace in the fall, creating 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 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 Disregard
While it’s less common for a new system to require furnace repair, it happens. 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 covered in plastic to prevent shocks, and this smell is a sign that heat is melting this protective coating. To hinder a fire, turn off your furnace as soon as possible and have it inspected out by an HVAC technician.
- Gas or rotten eggs. Gas companies include sulfur in natural gas to signal you when there’s a problem. If your furnace smells like gas or rotten eggs, turn it off as soon as possible, get out of your home and call 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 flourishing in your ductwork. We recommend having your ductwork examined and cleaned if necessary.
