Have you recently had a new furnace installed and are now having an unusual smell? You’re not alone, because many other homeowners also experience this at first. Let’s review what’s leading to this smell, and when you can expect it to go away, as well as three other furnace smells you shouldn’t disregard.
Why Your New Furnace Smells
There are two reasons why a new furnace might reek.
Your furnace has a special coating on certain parts to keep them from rusting. This may include the heat exchanger, which safely exhausts gases including carbon monoxide naturally made during the heating process.
When your furnace operates for the first couple of times, the coating may release 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 contact 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 idle in the spring and summer. That dust will burn off when you switch on your furnace in the fall, producing 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 needed to keep your valuable manufacturer’s warranty valid, plus it keeps your furnace clean and ensures it will run perfectly during the upcoming heating time of year.
3 Other Furnace Smells You Shouldn’t Dismiss
While it’s less common for a new system to necessitate furnace repair, it can happen. 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 avoid shocks, and this smell is a signal that heat is melting this preventive coating. To hinder 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 signal you when there’s a problem. If your furnace smells like gas or rotten eggs, turn it off right away, evacuate your home and dial 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 suggest having your ductwork inspected and cleaned if necessary.
