Have you recently had a new furnace put in and are now noticing an unusual smell? You’re not alone, because many other homeowners also have this happen at first. Let’s review what’s leading to 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 explanations why a new furnace might reek.
Your furnace has a special coating on some parts to keep them from rusting. This may include the heat exchanger, which safely removes gases like carbon monoxide naturally produced during the heating process.
When your furnace starts 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 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 has overheated or there’s an electrical problem, among other problems.
Dust accumulates inside your furnace when it’s not running in warm weather. That dust will burn off when you switch on your furnace in the fall, producing a burning smell. This smell should subside within a few minutes.
One way you can lessen or prevent this smell is by having furnace maintenance done every year. This is required to keep your valuable manufacturer’s warranty good, plus it keeps your furnace clean and ensures it will run properly during the upcoming heating time of year.
3 Other Furnace Smells You Shouldn’t Ignore
While it’s less common for a new system to require furnace repair, it happens. Here are three other scents 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 issue. Electrical wiring is covered in plastic to protect against shocks, and this smell is a sign that heat is melting this preventive coating. To hinder a fire, turn off your furnace right away and have it checked out by an HVAC technician.
- Gas or rotten eggs. Gas companies include sulfur in natural gas to warn you when there’s a problem. If your furnace smells like gas or rotten eggs, shut it off right away, get out of your home and dial 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 growing in your ductwork. We advise having your ductwork checked and cleaned if needed.
