Have you recently had a new furnace put in and are now experiencing a weird smell? You’re not alone, because plenty of other homeowners also experience this at first. Let’s review what’s creating this smell, and when you can expect it to subside, as well as three other furnace smells you shouldn’t neglect.
Why Your New Furnace Smells
There are two explanations why a new furnace might smell.
Your furnace has a special application on some parts to keep them from rusting. This may include the heat exchanger, which safely exhausts gases like carbon monoxide naturally created 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 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 lingers can mean the motor has overheated or there’s an electrical problem, among other issues.
Dust accumulates inside your furnace when it’s off in the spring and summer. That dust will burn off when you turn on your furnace in the fall, producing 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 year. This is necessary 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 Dismiss
While it’s less common for a new system to need 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 coated in plastic to protect against shocks, and this smell is a sign that heat is melting this precautionary coating. To hinder a fire, turn off your furnace immediately 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 leak. If your furnace smells like gas or rotten eggs, shut it off right away, leave your home and contact 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 recommend having your ductwork examined and cleaned if needed.
