Have you recently had a new furnace put in and are now experiencing a strange smell? You’re not alone, because many other homeowners also experience this at first. Let’s review what’s creating 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 stink.
Your furnace has a special coating on certain parts to keep them from rusting. This may include the heat exchanger, which safely gets rid of gases such as carbon monoxide naturally produced during the heating process.
When your furnace runs for the first couple of times, the coating may release a burning smell. This is normal and the smell should disperse 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 is too hot 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 switch on your furnace in the fall, producing a burning smell. This smell should subside 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 applicable, plus it keeps your furnace clean and ensures it will run properly during the upcoming heating season.
3 Other Furnace Smells You Shouldn’t Disregard
While it’s less common for a new system to necessitate 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 protected in plastic to protect against shocks, and this smell is an indication that heat is melting this preventive coating. To hinder a fire, shut off your furnace as soon as possible and have it examined out by an HVAC technician.
- Gas or rotten eggs. Gas companies add sulfur to natural gas to signal you when there’s a problem. If your furnace smells like gas or rotten eggs, turn it off as soon as possible, leave your home and call 911. Exposure to natural gas can make you ill, plus it’s extremely flammable and explosive.
- Musty. If your furnace smells musty, you might have mold and mildew developing in your ductwork. We advise having your ductwork examined and cleaned if required.
