“Our basement had a sump pump back up with the recent record setting rainfall and simultaneous power outage. Kettle Moraine Heating and Cooling came out the same day we called! They did a comprehensive check of furnace, water heater and electric panel. Thankfully all, even though being significantly old, were deemed to be working and safe. Damyon was super professional, informative and friendly! I would highly recommend this company.“

“Two ambitious projects in the past year: 2 new replacement boilers and 2 new air conditioning systems. All four were professionally installed, at budget, and on time. The high pressure A/C is unobtrusive, and the new heating takes up maybe 20% of the old system. Special shout out to Brian, Larry, Carl, and Tim. Quite a crew.“

“Yoders has saved me twice this year! First my A/C broke this summer and I had others come look at it. They only wanted to sell me a new unit. Not Yoders! They repaired my unit until we were able to replace it and I was so thankful! Today my furnace broke … I knew better than to call anyone else this time! Thomas came out and repaired our furnace so we could have heat and are planning to replace the furnace too. They are fast, friendly and highly capable and great prices too! Highly recommend them!“
