Have you recently had a new furnace installed and are now experiencing a strange 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 disappear, as well as three other furnace smells you shouldn’t disregard.
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 created during the heating process.
When your furnace starts for the first couple of times, the coating may release a burning smell. This is normal and the smell should disperse the more your furnace runs.
To be on the safe side, you’ll want to call 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 issues.
Dust accumulates inside your furnace when it’s idle in the spring and summer. That dust will burn off when you flip on your furnace in the fall, producing a burning smell. This smell should disappear within a few minutes.
One way you can lessen or prevent this smell is by having furnace maintenance done every year. This is necessary to keep your valuable manufacturer’s warranty good, 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 need furnace repair, it can happen. Here are three other scents 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 issue. Electrical wiring is coated in plastic to protect against shocks, and this smell is a sign that heat is melting this protective coating. To hinder a fire, shut off your furnace right away and have it inspected 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 immediately, leave your home and contact 911. Exposure to natural gas can make you sick, plus it’s extremely flammable and explosive.
- Musty. If your furnace smells musty, you might have mold and mildew developing in your ductwork. We recommend having your ductwork examined and cleaned if required.
