Have you recently had a new furnace put in and are now having 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 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 reasons 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 like carbon monoxide naturally made 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 persists. A burning smell that sticks around can mean the motor is too hot or there’s an electrical problem, among other issues.
Dust accumulates inside your furnace when it’s not running in the summer. That dust will burn off when you flip on your furnace in the fall, producing a burning smell. This smell should go away within a few minutes.
One way you can reduce or prevent this smell is by having furnace maintenance done each year. This is required to keep your valuable manufacturer’s warranty good, plus it keeps your furnace clean and ensures it will run perfectly during the upcoming heating season.
3 Other Furnace Smells You Shouldn’t Dismiss
While it’s less common for a new system to require furnace repair, it happens. 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 issue. Electrical wiring is coated in plastic to protect against shocks, and this smell is an indication that heat is melting this precautionary coating. To hinder a fire, turn off your furnace right away and have it examined out by an HVAC technician.
- Gas or rotten eggs. Gas companies include sulfur in natural gas to warn you when there’s a leak. If your furnace smells like gas or rotten eggs, shut it off right away, get out of your home and call 911. Exposure to natural gas can make you ill, plus it’s very flammable and explosive.
- Musty. If your furnace smells musty, you might have mold and mildew growing in your ductwork. We suggest having your ductwork checked and cleaned if necessary.
