Have you recently had a new furnace installed and are now noticing a strange smell? You’re not alone, because plenty 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 subside, 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 reek.
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 produced during the heating process.
When your furnace operates for the first couple of times, the coating may emit a burning smell. This is normal and the smell should dissipate the more your furnace runs.
To be on the safe side, you’ll want to call a heating and cooling company if the smell persists. A burning smell that remains can mean the motor has overheated or there’s an electrical problem, among other issues.
Dust accumulates inside your furnace when it’s idle in the spring and summer. That dust will burn off when you switch 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 good, plus it keeps your furnace clean and ensures it will run smoothly 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 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 coated in plastic to protect against shocks, and this smell is a sign that heat is melting this protective coating. To avoid a fire, switch off your furnace as soon as possible 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 leakage. If your furnace smells like gas or rotten eggs, turn it off right away, get out of 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 suggest having your ductwork examined and cleaned if necessary.
