Have you recently had a new furnace put in and are now experiencing a weird smell? You're not alone, because plenty of 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 factors why a new furnace might reek.
Protective Finish
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 starts for the first couple of times, the coating may emit a burning smell. This is typical and the smell should disperse the more your furnace operates.
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 remains can mean the motor has overheated or there’s an electrical problem, among other issues.
Dust
Dust builds 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, creating a burning smell. This smell should subside within a few minutes.
One way you can decrease or prevent this smell is by having furnace maintenance done every year. This is necessary 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 Disregard
While it’s less common for a new system to necessitate furnace repair, it happens. 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 protected in plastic to protect against shocks, and this smell is an indication that heat is melting this precautionary 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 leakage. If your furnace smells like gas or rotten eggs, turn it off right away, leave your home and call 911. Exposure to natural gas can make you unwell, plus it’s highly flammable and explosive.
- Musty. If your furnace smells musty, you might have mold and mildew developing in your ductwork. We suggest having your ductwork checked and cleaned if required.
