Why Your Furnace Smells Strange

November 29, 2016

Most homeowners in Hillsborough know to call Fras-Air/General Service Experts when their furnace starts making funny noises or leaking water, but did you know that strange smells are another basis to call an expert? Check out these furnace smells you should never disregard.

Rotten Eggs

The stench of rotten eggs is very pronounced, which is why multiple gas companies add this recognizable odor to their gas to warn homeowners and technicians that there is an issue. If you smell this stench coming from your furnace, shut off your gas appliances straightaway as you could have a gas leak. Open your doors and windows so any gas can vent outside, and call your heating equipment service technician as soon as possible and tell them you think you may have a gas leak.

Mold or Musty

Your heating and cooling system work together to keep you comfortable throughout the entire year. Since AC systems can cause condensation buildup, moisture can manifest in your air duct system and create mold, producing the musty or moldy odor. If you turn on your heating equipment or A/C equipment and smell an odor like this, call Fras-Air/General Service Experts. We’ll come over ASAP to analyze your duct system and conduct an indoor air quality analysis. We can then provide you suggestions on how to remove the source of the odor and make sure your HVAC system is ready to keep you toasty and healthy all winter long.

Electrical or Burning

There are several things that could be occurring if you smell an electrical or burning odor, all of which should grab your attention and should not be ignored. If you have this stench coming from your furnace, it’s likely something is overheating or may be an indication of wiring problems. Shut down your heating system right away and call your furnace technician to provide a complete diagnosis.
