Have you recently had a new furnace set up and are now having an unusual 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 look forward to it to go away, as well as three other furnace smells you shouldn’t ignore.
Why Your New Furnace Smells
There are two reasons why a new furnace might stink.
Your furnace has a special finish on some parts to keep them from rusting. This may include the heat exchanger, which safely removes gases including carbon monoxide naturally created during the heating process.
When your furnace starts for the first couple of times, the coating may emit a burning smell. This is typical 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 continues. A burning smell that lingers can mean the motor is too hot or there’s an electrical problem, among other issues.
Dust collects inside your furnace when it’s off in the spring and summer. That dust will burn off when you flip on your furnace in the fall, producing 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 necessary to keep your valuable manufacturer’s warranty valid, plus it keeps your furnace clean and ensures it will run perfectly during the upcoming heating period.
3 Other Furnace Smells You Shouldn’t Disregard
While it’s less common for a new system to require furnace repair, it can happen. Here are three other smells 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 issue. Electrical wiring is protected in plastic to protect against shocks, and this smell is a signal that heat is melting this precautionary coating. To hinder a fire, shut off your furnace right away and have it inspected out by an HVAC technician.
- Gas or rotten eggs. Gas companies include sulfur in natural gas to alert you when there’s a problem. 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 unwell, plus it’s extremely 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 required.
