Have you recently had a new furnace set up and are now having a weird smell? You’re not alone, because plenty of other homeowners also have this happen at first. Let’s review what’s causing this smell, and when you can anticipate it to subside, as well as three other furnace smells you shouldn’t neglect.
Why Your New Furnace Smells
There are two explanations why a new furnace might smell.
Your furnace has a special application on some parts to keep them from rusting. This may include the heat exchanger, which safely removes gases including carbon monoxide naturally made 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 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 lingers can mean the motor is too hot or there’s an electrical problem, among other issues.
Dust accumulates inside your furnace when it’s off in the summer. 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 single year. This is necessary to keep your valuable manufacturer’s warranty valid, plus it keeps your furnace clean and ensures it will run perfectly 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 keep an eye 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 protected in plastic to avoid shocks, and this smell is an indication that heat is melting this precautionary coating. To hinder a fire, shut off your furnace right away 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 leakage. If your furnace smells like gas or rotten eggs, turn it off as soon as possible, leave your home and contact 911. Exposure to natural gas can make you unwell, plus it’s extremely flammable and explosive.
- Musty. If your furnace smells musty, you might have mold and mildew growing in your ductwork. We suggest having your ductwork examined and cleaned if needed.
