Have you recently had a new furnace installed and are now noticing an unusual smell? You’re not alone, because a lot of other homeowners also have this happen at first. Let’s review what’s leading to 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 coating on some parts to keep them from rusting. This may include the heat exchanger, which safely exhausts 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 disperse the more your furnace operates.
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 remains can mean the motor is too hot or there’s an electrical problem, among other issues.
Dust accumulates inside your furnace when it’s off in warm weather. That dust will burn off when you switch on your furnace in the fall, making a burning smell. This smell should disappear within a few minutes.
One way you can reduce or prevent this smell is by having furnace maintenance done every year. This is required to keep your valuable manufacturer’s warranty good, plus it keeps your furnace clean and ensures it will run properly during the upcoming heating season.
3 Other Furnace Smells You Shouldn’t Dismiss
While it’s less common for a new system to necessitate 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 prevent shocks, and this smell is an indication that heat is melting this precautionary coating. To prevent a fire, shut off your furnace immediately and have it checked 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 as soon as possible, leave your home and call 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 developing in your ductwork. We advise having your ductwork inspected and cleaned if necessary.
