Do you know what are probably causing these odors? Read on and find out.

Burned Dust

You probably observed a burnt or musty smell when you turned on your furnace for the first time. Don’t fret; that’s normal. This is the smell of dust that settles in the components after the long months of being unused. However, the smell should not persist for more than a few days. If it does, take time to check the filters and replace them if needed. If the smell continues, call a professional for a complete inspection.

Rotten Eggs

Does your furnace run on natural gas? If it does, then you’ll probably experience a smell like rotten eggs when you turn the unit on. A gas leak causes this. It is a complicated issue and may require you to leave your home immediately and call 911. As you leave your home, be sure to unplug all appliances, turn off the lights, and do not use your phone inside. You should drive your car to a neighbor’s home.

Dirty Socks

Have you experienced having a musty odor inside your home when the heat is on? The accumulation of mold or the presence of bacteria in your heating system is causing this. This happens most of the time for heat pumps. Schedule a cleaning service immediately for your unit and the ductworks.

Burning Rubber / Plastic

If you notice a burning rubber or plastic when your unit runs, you should take time to check the air vents in your home. See if there are rubber or plastic items placed on top or inside the registers and vents. Remove them immediately. If the odor persists, unplug the unit and call an HVAC expert for a complete diagnosis of your furnace in Brooklyn, NY.

Metallic Smell

Are you bothered by an electrical or metallic smell as your unit operates? This is probably a sign that your heating system is overheating due to faulty motors or tattered wires. Letting the unit work can only make the situation worse. Unplug it and call professional heating repair in Brooklyn, NY.
