Have you recently had a new furnace put in and are now noticing a strange smell? You’re not alone, because a lot of other homeowners also have this happen at first. Let’s review what’s leading to this smell, and when you can look forward to it to go away, as well as three other furnace smells you shouldn’t ignore.
Why Your New Furnace Smells
There are two reasons why a new furnace might smell.
Your furnace has a special application on certain parts to keep them from rusting. This may include the heat exchanger, which safely gets rid of gases including carbon monoxide naturally produced during the heating process.
When your furnace runs for the first couple of times, the coating may give off a burning smell. This is typical and the smell should go away the more your furnace operates.
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 has overheated or there’s an electrical problem, among other problems.
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, creating 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 each year. This is required to keep your valuable manufacturer’s warranty valid, plus it keeps your furnace clean and ensures it will run smoothly during the upcoming heating season.
3 Other Furnace Smells You Shouldn’t Dismiss
While it’s less common for a new system to require furnace repair, it can happen. 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 covered in plastic to avoid shocks, and this smell is an indication that heat is melting this precautionary coating. To prevent 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 alert you when there’s a leakage. If your furnace smells like gas or rotten eggs, shut it off as soon as possible, evacuate 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 developing in your ductwork. We suggest having your ductwork checked and cleaned if necessary.
