Have you recently had a new furnace installed and are now experiencing 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 subside, as well as three other furnace smells you shouldn’t disregard.
Why Your New Furnace Smells
There are two factors why a new furnace might reek.
Your furnace has a special application 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 starts for the first couple of times, the coating may give off a burning smell. This is normal and the smell should dissipate the more your furnace runs.
To be on the safe side, you’ll want to call a heating and cooling company if the smell continues. A burning smell that remains can mean the motor has overheated or there’s an electrical problem, among other issues.
Dust accumulates inside your furnace when it’s not running in warm weather. That dust will burn off when you flip on your furnace in the fall, making 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 needed to keep your valuable manufacturer’s warranty good, plus it keeps your furnace clean and ensures it will run properly 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 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 problem. Electrical wiring is coated in plastic to protect against shocks, and this smell is a signal that heat is melting this protective coating. To hinder a fire, turn off your furnace immediately and have it checked out by an HVAC technician.
- Gas or rotten eggs. Gas companies add sulfur to natural gas to warn you when there’s a problem. If your furnace smells like gas or rotten eggs, turn it off immediately, evacuate your home and dial 911. Exposure to natural gas can make you unwell, plus it’s very flammable and explosive.
- Musty. If your furnace smells musty, you might have mold and mildew flourishing in your ductwork. We recommend having your ductwork inspected and cleaned if required.
