Heating & Air Conditioning / HVAC near Markesan

“we needed to replace our older furnace but didn't really know a reliable service. superheat was recommended by a friend and all I can say is WOW! Super friendly to work with and great service! The techs who installed the new unit were super to work with and respectable about our pets and new furnace turnoff smell. HIGHLY RECOMMEND this business! 25 out of 10 star rating from us!“

“I initially contacted the after hours service on Christmas Eve 2025. My phone call was returned a short time later on the same day. I was located in Texas at the time. The staff was professional and provided expert advice related to the house located in WI and the upcoming weather, as the residence was not occupied at the time. They outlined a plan which was centered around common sense and the best bang for the dollar in scheduling a technician to respond and troubleshoot the heat related issue. Air Tech was recommended to me as a trustworthy and skilled HVAC business and I found this to be accurate and true.“
