Have you recently had a new furnace set up and are now having a strange smell? You’re not alone, because a lot of other homeowners also have this happen at first. Let’s review what’s creating this smell, and when you can anticipate 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 stink.
Your furnace has a special application on certain parts to keep them from rusting. This may include the heat exchanger, which safely removes gases like carbon monoxide naturally produced during the heating process.
When your furnace starts for the first couple of times, the coating may give off a burning smell. This is normal and the smell should dissipate the more your furnace operates.
To be on the safe side, you’ll want to contact a heating and cooling company if the smell continues. A burning smell that sticks around can mean the motor is too hot or there’s an electrical problem, among other problems.
Dust accumulates inside your furnace when it’s idle in the summer. 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 reduce 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 perfectly during the upcoming heating period.
3 Other Furnace Smells You Shouldn’t Ignore
While it’s less common for a new system to need furnace repair, it happens. Here are three other smells you should watch 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 precautionary coating. To prevent a fire, turn off your furnace immediately and have it inspected out by an HVAC technician.
- Gas or rotten eggs. Gas companies add sulfur to natural gas to warn you when there’s a leak. If your furnace smells like gas or rotten eggs, turn it off immediately, evacuate your home and call 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 developing in your ductwork. We suggest having your ductwork examined and cleaned if required.
