Have you recently had a new furnace set up and are now noticing a weird smell? You’re not alone, because a lot of other homeowners also experience this at first. Let’s review what’s creating this smell, and when you can look forward to it to go away, 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 reek.
Your furnace has a special application on some parts to keep them from rusting. This may include the heat exchanger, which safely gets rid of gases including carbon monoxide naturally produced during the heating process.
When your furnace runs for the first couple of times, the coating may release a burning smell. This is standard and the smell should go away the more your furnace heats.
To be on the safe side, you’ll want to connect with a heating and cooling company if the smell persists. A burning smell that lingers can mean the motor is too hot or there’s an electrical problem, among other issues.
Dust builds inside your furnace when it’s off in the spring and summer. That dust will burn off when you switch on your furnace in the fall, creating a burning smell. This smell should subside within a few minutes.
One way you can decrease 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 require furnace repair, it can happen. Here are three other smells 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 protected in plastic to avoid shocks, and this smell is an indication that heat is melting this protective coating. To avoid a fire, switch off your furnace immediately and have it examined out by an HVAC technician.
- Gas or rotten eggs. Gas companies include sulfur in natural gas to alert you when there’s a leakage. If your furnace smells like gas or rotten eggs, turn it off immediately, evacuate your home and dial 911. Exposure to natural gas can make you sick, plus it’s highly flammable and explosive.
- Musty. If your furnace smells musty, you might have mold and mildew flourishing in your ductwork. We suggest having your ductwork examined and cleaned if needed.
