Have you recently had a new furnace set up and are now having a strange smell? You’re not alone, because many other homeowners also have this happen at first. Let’s review what’s leading to this smell, and when you can anticipate it to disappear, 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 smell.
Your furnace has a special application on certain parts to keep them from rusting. This may include the heat exchanger, which safely exhausts gases such as 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 heats.
To be on the safe side, you’ll want to call 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 concerns.
Dust accumulates inside your furnace when it’s not running 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 every single year. This is required to keep your valuable manufacturer’s warranty applicable, plus it keeps your furnace clean and ensures it will run smoothly during the upcoming heating season.
3 Other Furnace Smells You Shouldn’t Ignore
While it’s less common for a new system to necessitate furnace repair, it happens. Here are three other scents 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 difficulties. Electrical wiring is coated in plastic to prevent shocks, and this smell is a sign that heat is melting this precautionary coating. To avoid a fire, switch off your furnace as soon as possible 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 leakage. If your furnace smells like gas or rotten eggs, shut it off immediately, get out of your home and dial 911. Exposure to natural gas can make you ill, plus it’s highly flammable and explosive.
- Musty. If your furnace smells musty, you might have mold and mildew flourishing in your ductwork. We advise having your ductwork examined and cleaned if needed.
