Why Your Furnace Smells Strange

November 29, 2016

Most people in Houston know to call Service Experts Heating & Air Conditioning when their furnace starts making funny noises or leaking water, but did you know that weird smells are another cause to call a service technician? Check out these heating equipment odors you should never disregard.

Rotten Eggs

The odor 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 a problem. If you smell this odor coming from your furnace, shut 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 furnace service expert as soon as possible and be sure they know you think you might have a gas leak.

Mold or Musty

Your heating and cooling equipment work together to keep you comfy throughout all the seasons. Since A/C systems can cause condensation to accumulate, moisture can manifest in your air duct system and cause mold, creating the musty or moldy stench. If you turn on your furnace or A/C equipment and smell an odor like this, call Service Experts Heating & Air Conditioning. We’ll come over ASAP to analyze your duct system and do an indoor air quality analysis. We can then give you recommendations on how to remove the source of the smell 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 occurring if you smell an electrical or burning odor, all of which should grab your attention and should not be neglected. If you have this stench coming from your furnace, it’s probable something is overheating or may be a signal of wiring problems. Turn off your furnace right away and call your furnace professional to provide a thorough diagnosis.
