Have you recently had a new furnace installed and are now noticing a weird smell? You’re not alone, because a lot of 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 disappear, as well as three other furnace smells you shouldn’t ignore.
Why Your New Furnace Smells
There are two factors why a new furnace might stink.
Your furnace has a special application on specific 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 typical and the smell should dissipate 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 persists. A burning smell that remains can mean the motor is too hot or there’s an electrical problem, among other problems.
Dust builds inside your furnace when it’s not running in the 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 decrease or prevent this smell is by having furnace maintenance done each year. This is needed to keep your valuable manufacturer’s warranty valid, plus it keeps your furnace clean and ensures it will run properly 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 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 problem. Electrical wiring is covered in plastic to protect against shocks, and this smell is a sign that heat is melting this precautionary coating. To prevent a fire, switch off your furnace right away and have it examined out by an HVAC technician.
- Gas or rotten eggs. Gas companies add sulfur to natural gas to alert you when there’s a leak. If your furnace smells like gas or rotten eggs, turn it off immediately, leave your home and dial 911. Exposure to natural gas can make you unwell, plus it’s highly flammable and explosive.
- Musty. If your furnace smells musty, you might have mold and mildew growing in your ductwork. We recommend having your ductwork examined and cleaned if needed.
