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 causing this smell, and when you can anticipate it to disappear, as well as three other furnace smells you shouldn’t neglect.
Why Your New Furnace Smells
There are two reasons why a new furnace might smell.
Your furnace has a special finish 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 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 runs.
To be on the safe side, you’ll want to call a heating and cooling company if the smell continues. A burning smell that sticks around can mean the motor is too hot or there’s an electrical problem, among other concerns.
Dust collects inside your furnace when it’s not running in warm weather. That dust will burn off when you turn on your furnace in the fall, creating 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 good, plus it keeps your furnace clean and ensures it will run properly during the upcoming heating period.
3 Other Furnace Smells You Shouldn’t Disregard
While it’s less common for a new system to necessitate furnace repair, it can happen. Here are three other odors you should watch 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 protect against shocks, and this smell is an indication that heat is melting this precautionary coating. To avoid a fire, switch off your furnace as soon as possible and have it examined out by an HVAC technician.
- Gas or rotten eggs. Gas companies add sulfur to natural gas to signal you when there’s a leakage. If your furnace smells like gas or rotten eggs, turn it off right away, evacuate your home and call 911. Exposure to natural gas can make you unwell, 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 checked and cleaned if necessary.
