Have you recently had a new furnace installed and are now having a weird smell? You’re not alone, because many 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 ignore.
Why Your New Furnace Smells
There are two factors why a new furnace might reek.
Your furnace has a special application on specific 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 dissipate the more your furnace runs.
To be on the safe side, you’ll want to contact a heating and cooling company if the smell lingers. A burning smell that sticks around can mean the motor is too hot or there’s an electrical problem, among other concerns.
Dust builds inside your furnace when it’s idle 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 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 Dismiss
While it’s less common for a new system to necessitate 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 difficulties. Electrical wiring is coated in plastic to protect against shocks, and this smell is a sign that heat is melting this protective coating. To avoid a fire, turn off your furnace immediately and have it inspected out by an HVAC technician.
- Gas or rotten eggs. Gas companies include sulfur in natural gas to warn you when there’s a leakage. If your furnace smells like gas or rotten eggs, turn it off immediately, get out of your home and contact 911. Exposure to natural gas can make you sick, plus it’s highly flammable and explosive.
- Musty. If your furnace smells musty, you might have mold and mildew growing in your ductwork. We suggest having your ductwork inspected and cleaned if needed.
