Have you recently had a new furnace set up and are now noticing a weird smell? You’re not alone, because plenty of other homeowners also experience this at first. Let’s review what’s leading to this smell, and when you can anticipate it to go away, as well as three other furnace smells you shouldn’t disregard.
Why Your New Furnace Smells
There are two explanations why a new furnace might stink.
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 produced during the heating process.
When your furnace operates for the first couple of times, the coating may release a burning smell. This is normal and the smell should disperse the more your furnace heats.
To be on the safe side, you’ll want to call a heating and cooling company if the smell lingers. 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 off in the summer. 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 single year. This is needed 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 necessitate furnace repair, it can happen. Here are three other smells 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 difficulties. Electrical wiring is coated in plastic to prevent shocks, and this smell is a sign that heat is melting this protective coating. To avoid a fire, switch off your furnace right away and have it examined out by an HVAC technician.
- Gas or rotten eggs. Gas companies add sulfur to natural gas to alert you when there’s a leakage. If your furnace smells like gas or rotten eggs, turn 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 advise having your ductwork inspected and cleaned if required.
