Have you recently had a new furnace installed and are now experiencing a weird smell? You’re not alone, because a lot of other homeowners also experience this at first. Let’s review what’s creating this smell, and when you can expect it to go away, as well as three other furnace smells you shouldn’t disregard.
Why Your New Furnace Smells
There are two factors why a new furnace might reek.
Your furnace has a special coating on some parts to keep them from rusting. This may include the heat exchanger, which safely gets rid of gases like carbon monoxide naturally produced 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 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 lingers. A burning smell that sticks around can mean the motor has overheated or there’s an electrical problem, among other problems.
Dust collects inside your furnace when it’s off 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 every year. This is necessary 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 Ignore
While it’s less common for a new system to require 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 issue. Electrical wiring is coated in plastic to avoid shocks, and this smell is a sign that heat is melting this precautionary coating. To avoid a fire, switch off your furnace immediately and have it inspected out by an HVAC technician.
- Gas or rotten eggs. Gas companies add sulfur to natural gas to warn you when there’s a leakage. If your furnace smells like gas or rotten eggs, shut it off immediately, evacuate 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 growing in your ductwork. We advise having your ductwork inspected and cleaned if needed.
