Why Your Furnace Smells Strange

November 29, 2016

Most people in Grand Island know to call McElroy Service Experts when their heating system starts making funny noises or leaking water, but did you know that weird smells are another cause to call a professional? Read about these heating equipment smells you should never ignore.

Rotten Eggs

The stench of rotten eggs is very distinct, which is why multiple gas companies add this distinct odor to their gas to notify homeowners and furnace experts that there is an issue. If you smell this odor coming from your heating equipment, power off your gas appliances immediately as you could have a gas leak. Open the doors and windows so any gas can release outside, and call your heating equipment service expert as soon as possible and tell them you think you may have a gas leak.

Mold or Musty

Your heating and cooling equipment work together to keep you comfortable throughout all the seasons. Since A/C systems can cause condensation to accumulate, moisture can get in your air duct system and produce mold, creating the musty or moldy smell. If you turn on your furnace or A/C equipment and smell an odor like this, call McElroy 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 eliminate the source of the stench and make sure your HVAC 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 stench, all of which should get your attention and should not be disregarded. If you have this odor coming from your furnace, it’s probable something is overheating or may be an indication of wiring problems. Shut off your furnace right away and call your furnace technician to provide a full diagnosis.
