Why Your Furnace Smells Strange

November 29, 2016

Most residents in Saint Charles know to call Golden Seal Service Experts Heating & Air Conditioning when their heating system starts making funny noises or leaking water, but did you know that weird smells are another reason to call a professional? Learn about these furnace smells you should never neglect.

Rotten Eggs

The smell of rotten eggs is very distinct, which is why several gas companies add this pronounced odor to their gas to notify homeowners and technicians that there is an issue. If you smell this odor coming from your heating system, power off your gas appliances right away as you could have a gas leak. Open your doors and windows so any gas can escape outside, and call your heating equipment service professional as soon as possible and tell them you think you could have a gas leak.

Mold or Musty

Your heating and cooling equipment work together to keep you comfy throughout the year. Since AC systems can cause condensation to accumulate, moisture can get in your air duct system and create mold, producing the musty or moldy smell. If you turn on your furnace or A/C equipment and smell an odor like this, call Golden Seal Service Experts Heating & Air Conditioning. We’ll come over ASAP to examine your duct system and do an indoor air quality analysis. We can then provide you suggestions on how to remove the source of the stench and make sure your heating and cooling system is ready to keep you comfortable and healthy all winter long.

Electrical or Burning

There are multiple things that could be going on if you smell an electrical or burning odor, all of which should demand your attention and should not be neglected. If you have this smell coming from your furnace, it’s probable 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.
