Have you recently had a new furnace installed and are now experiencing a strange 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 expect it to disappear, as well as three other furnace smells you shouldn’t disregard.
Why Your New Furnace Smells
There are two reasons why a new furnace might smell.
Your furnace has a special coating on specific parts to keep them from rusting. This may include the heat exchanger, which safely exhausts 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 connect with a heating and cooling company if the smell lingers. A burning smell that lingers can mean the motor is too hot or there’s an electrical problem, among other concerns.
Dust builds inside your furnace when it’s off in warm weather. That dust will burn off when you switch on your furnace in the fall, producing a burning smell. This smell should subside within a few minutes.
One way you can reduce or prevent this smell is by having furnace maintenance done every year. This is required 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 need furnace repair, it can happen. Here are three other odors 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 avoid shocks, and this smell is an indication that heat is melting this protective coating. To avoid a fire, switch off your furnace immediately and have it examined out by an HVAC technician.
- Gas or rotten eggs. Gas companies add sulfur to natural gas to signal you when there’s a problem. If your furnace smells like gas or rotten eggs, shut it off as soon as possible, 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 flourishing in your ductwork. We recommend having your ductwork examined and cleaned if required.
