Have you recently had a new furnace put in 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 leading to this smell, and when you can expect it to disappear, 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 specific parts to keep them from rusting. This may include the heat exchanger, which safely gets rid of gases like carbon monoxide naturally created during the heating process.
When your furnace operates 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 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 remains 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 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 subside within a few minutes.
One way you can lessen or prevent this smell is by having furnace maintenance done every single year. This is necessary to keep your valuable manufacturer’s warranty applicable, 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 need 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 difficulties. Electrical wiring is coated in plastic to avoid shocks, and this smell is a sign that heat is melting this preventive coating. To hinder a fire, turn off your furnace immediately and have it examined 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, leave your home and dial 911. Exposure to natural gas can make you sick, plus it’s very flammable and explosive.
- Musty. If your furnace smells musty, you might have mold and mildew developing in your ductwork. We advise having your ductwork examined and cleaned if required.
