HVAC Service in Williamson County, Jackson County & Franklin County

Ponder Service is a full-service heating & air conditioning contracting business, family-owned by Mike, Florence, and Andy Ponder.  In business since 1984, we relocated to Marion, IL (Mike’s Hometown) in 1996. Our basic business plan has always been to provide high-quality products & services at fair and reasonable rates.

In 1996, we began installing Geothermal Heating Systems and today install Climatemaster Geothermal Systems. Over the years, we have steadily built up our sheet metal shop to the point where we now use computer designed duct layout and fabricating equipment, allowing us to build and install some of the finest duct systems in the area.
