Why Your Furnace Has a Strange Smell Published on November 29, 2016 Most homeowners in Salt Lake City know to call Service Experts Heating & Air Conditioning when their heating system starts making weird noises or leaking water, but did you know that funny smells are another reason to call a service technician? Learn about these furnace smells you should never neglect. Rotten Eggs The smell of rotten eggs is very distinct, which is why many gas companies add this distinct odor to their gas to alert homeowners and technicians that there is a problem. If you smell this smell coming from your heating equipment, power off your gas appliances immediately as you could have a gas leak. Open your windows and doors so any gas can release outside, and call your heating equipment service professional as soon as possible and let them know you think you could have a gas leak. Mold or Musty Your heating and cooling equipment operate together to keep you comfy throughout all the seasons. Since AC systems can cause condensation to accumulate, moisture can form in your air duct system and produce mold, producing the musty or moldy odor. If you turn on your heating system or AC system and smell an odor like this, call Service Experts Heating & Air Conditioning. We’ll come over immediately to examine your duct system and perform an indoor air quality analysis. We can then provide you suggestions on how to remove the source of the stench and make sure your HVAC system is ready to keep you toasty and healthy all winter long. Electrical or Burning There are multiple things that could be taking place if you smell an electrical or burning stench, all of which should grab your attention and should not be disregarded. If you have this stench coming from your heating system, it’s likely something is overheating or may be a signal of wiring problems. Shut down your heating equipment right away and call your furnace professional to provide a thorough diagnosis.
