Have you recently had a new furnace set up and are now having a strange smell? You’re not alone, because many other homeowners also have this happen at first. Let’s review what’s creating this smell, and when you can look forward to 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 reek.
Your furnace has a special coating on certain parts to keep them from rusting. This may include the heat exchanger, which safely exhausts gases such as carbon monoxide naturally produced 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 persists. A burning smell that sticks around can mean the motor has overheated or there’s an electrical problem, among other concerns.
Dust accumulates inside your furnace when it’s not running in the 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 decrease or prevent this smell is by having furnace maintenance done each year. This is needed to keep your valuable manufacturer’s warranty valid, plus it keeps your furnace clean and ensures it will run smoothly during the upcoming heating period.
3 Other Furnace Smells You Shouldn’t Ignore
While it’s less common for a new system to necessitate furnace repair, it can happen. 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 a sign that heat is melting this preventive coating. To avoid a fire, turn off your furnace as soon as possible and have it examined out by an HVAC technician.
- Gas or rotten eggs. Gas companies include sulfur in natural gas to alert you when there’s a problem. If your furnace smells like gas or rotten eggs, shut it off as soon as possible, leave your home and contact 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 suggest having your ductwork inspected and cleaned if needed.
