Have you recently had a new furnace installed and are now experiencing a weird smell? You're not alone, because many other homeowners also have this happen at first. Let’s review what’s causing this smell, and when you can expect it to go away, as well as three other furnace smells you shouldn’t ignore.
Why Your New Furnace Smells
There are two explanations why a new furnace might smell.
Your furnace has a special coating on specific parts to keep them from rusting. This may include the heat exchanger, which safely gets rid of gases like carbon monoxide naturally created during the heating process.
When your furnace runs for the first couple of times, the coating may emit a burning smell. This is standard and the smell should go away the more your furnace runs.
To be on the safe side, you’ll want to contact a heating and cooling company if the smell continues. A burning smell that lingers can mean the motor is too hot or there’s an electrical problem, among other issues.
Dust collects inside your furnace when it’s not running in warm weather. That dust will burn off when you turn on your furnace in the fall, producing a burning smell. This smell should disappear 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 valid, plus it keeps your furnace clean and ensures it will run properly during the upcoming heating season.
3 Other Furnace Smells You Shouldn’t Ignore
While it’s less common for a new system to need 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 problem. Electrical wiring is coated in plastic to prevent shocks, and this smell is a sign that heat is melting this precautionary coating. To prevent a fire, turn off your furnace immediately and have it checked out by an HVAC technician.
- Gas or rotten eggs. Gas companies include sulfur in natural gas to warn you when there’s a problem. If your furnace smells like gas or rotten eggs, turn it off immediately, 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 flourishing in your ductwork. We recommend having your ductwork checked and cleaned if needed.
