Have you recently had a new furnace put in and are now noticing a weird 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 subside, as well as three other furnace smells you shouldn’t neglect.
Why Your New Furnace Smells
There are two reasons why a new furnace might stink.
Your furnace has a special finish on certain parts to keep them from rusting. This may include the heat exchanger, which safely removes gases such as 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 standard and the smell should disperse the more your furnace runs.
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 remains can mean the motor has overheated or there’s an electrical problem, among other issues.
Dust collects inside your furnace when it’s not running 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 go away within a few minutes.
One way you can reduce or prevent this smell is by having furnace maintenance done every year. This is necessary 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 need furnace repair, it happens. Here are three other scents 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 difficulties. Electrical wiring is covered in plastic to protect against shocks, and this smell is a signal that heat is melting this protective coating. To hinder a fire, switch off your furnace right away and have it inspected out by an HVAC technician.
- Gas or rotten eggs. Gas companies add sulfur to natural gas to alert you when there’s a leakage. If your furnace smells like gas or rotten eggs, turn it off as soon as possible, evacuate your home and call 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 developing in your ductwork. We recommend having your ductwork examined and cleaned if required.
