Have you recently had a new furnace put in 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 leading to 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 factors why a new furnace might reek.
Your furnace has a special finish on certain 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 operates for the first couple of times, the coating may give off a burning smell. This is typical and the smell should go away the more your furnace heats.
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 problems.
Dust accumulates inside your furnace when it’s idle 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 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 time of year.
3 Other Furnace Smells You Shouldn’t Dismiss
While it’s less common for a new system to need furnace repair, it can happen. Here are three other smells you should watch 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 covered in plastic to protect against shocks, and this smell is a signal that heat is melting this protective coating. To hinder a fire, shut 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, shut it off right away, leave your home and contact 911. Exposure to natural gas can make you sick, plus it’s very flammable and explosive.
- Musty. If your furnace smells musty, you might have mold and mildew growing in your ductwork. We advise having your ductwork examined and cleaned if needed.
