Have you recently had a new furnace put in and are now experiencing a weird 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 neglect.
Why Your New Furnace Smells
There are two explanations why a new furnace might stink.
Your furnace has a special application on specific parts to keep them from rusting. This may include the heat exchanger, which safely gets rid of gases like carbon monoxide naturally created during the heating process.
When your furnace runs for the first couple of times, the coating may emit a burning smell. This is standard and the smell should disperse the more your furnace operates.
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 is too hot or there’s an electrical problem, among other issues.
Dust accumulates inside your furnace when it’s not running in warm weather. That dust will burn off when you flip on your furnace in the fall, producing 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 year. This is necessary 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 Disregard
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 problem. Electrical wiring is coated in plastic to prevent shocks, and this smell is a signal 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 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, leave your home and contact 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 growing in your ductwork. We suggest having your ductwork examined and cleaned if required.
