Have you recently had a new furnace put in and are now having a weird smell? You’re not alone, because plenty of other homeowners also have this happen 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 disregard.
Why Your New Furnace Smells
There are two factors why a new furnace might stink.
Your furnace has a special finish on certain parts to keep them from rusting. This may include the heat exchanger, which safely gets rid of gases including carbon monoxide naturally created during the heating process.
When your furnace operates for the first couple of times, the coating may give off 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 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 collects inside your furnace when it’s off in warm weather. That dust will burn off when you switch on your furnace in the fall, producing a burning smell. This smell should go away within a few minutes.
One way you can decrease or prevent this smell is by having furnace maintenance done each year. This is required 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 Disregard
While it’s less common for a new system to require furnace repair, it happens. Here are three other odors 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 problem. Electrical wiring is protected in plastic to avoid shocks, and this smell is a sign that heat is melting this precautionary coating. To hinder 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 alert you when there’s a problem. If your furnace smells like gas or rotten eggs, shut it off as soon as possible, evacuate your home and dial 911. Exposure to natural gas can make you ill, plus it’s extremely 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 necessary.
