We were very pleased with the entire process from Kettle Moraine Heating and Air Conditioning. They provided us with multiple options to choose from to replace our broken furnace and air conditioner. These were given in a timely manner, with excellent customer service, and patience. Dane, Marc, Dustin, and Bill with his crew were fantastic. The prices were reasonable, the financing options were multiple, and we were able to select the financing option that best fit our needs. The work was done in about a half a day. The crew of three professionals led by Bill were courteous and friendly. They made sure that they cleaned up any mess that they made before they left and efficiently took out our old equipment. We definitely will be recommending them in the future if anyone we know of is looking for this type of work.

I switched to Kettle Marine heating and Air Conditioning because the contractor that installed my furnace in 2012 has gone downhill horribly with their service in the last two years. Jeremy was outstanding. I wish I'd been using him all this time. He pointed out so many things that the previous contractor should have done and didn't do. I feel so much better knowing he will be taken care of my air-conditioning in my furnace because his knowledge is excellent 09/23/26 Update: I had to get a new furnace because Ideal Mechanical installed my current furnace wrong and it corroded due to improper leveling. Jacob and Faith from Kettle Moraine installed my new furnace perfectly. They were very knowledgeable and thorough and installed the furnace very quickly. They were very patient and helped me with the new thermostat and my other questions. Another 5 star experience with Kettle Moraine Heating and Cooling

They were here on time! Got the job done and cleaned up nicely! Also took the old slab for me! I would hire them again!

I have known Brian for almost 20 yrs. He always does an outstanding job!!

I always appreciate the friendly professional service of Brent VonHofmann from Kettle Moraine Heating& Air Conditioning. He always goes the extra mile”extra mile to keep things running smoothly and provides me with “peace of mind” throughout the seasons. Thank you!

Lane did a fantastic job. Came In for a check up and was extremely informative and thorough in his inspection. He then shared the options we had to move forward and recommended a few best fits. Couldnt recommend him more and looking forward to having the kettle moraine team be our go to HVAC techs

Derek and Miguel appear to have done a great job! They also went above and beyond to keep our house clean during their work. Special thanks to Derek for his patient explanation of how to operate new equipment.

Annual furnace maintenance including humidifier and dehumidifier. All set for a Wisconsin winter. Miles was extremely helpful including explaining some things to watch out for in advance of downtime. Please send him again whenever I call for help. He is an asset for K M. Glad I signed onto a great service plan, worth the investment.

All around excellent work.

Friendly and knowledgeable technician.

Ryan arrived at scheduled time and covered flooring before starting removal of furnace. They ran into some assembly issues that were quickly resolved. Once new furnace and air conditioner were completed I was taken through use of unit and new thermostat set up. Once they were done they did a very good job of cleaning up and removing floor protection and all old furnace / air conditioning components .

Paul was great. He arrived on time, explained what he was doing and gave us tips for our HVAC system.

Jacob showed up on time preceded by a courtesy call as to when he’d arrive. Thorough in his scheduled maintenance of our AC. Kettle Moraine is our go to for our heating and cooling needs. Thanks. Great job.

Jim did a great job explaining the service to be completed during the scheduled appointment. He was able to find a solution to not having a water faucet outside the home. Jim reviewed the details of the service he completed when done running standard testing for the maintenance of the unit. He even helped schedule the furnace check for later this year.

Jacob did a nice job going over everything carefully and explaining our options.

Paul is the best for servicing my furnace and air conditioner!!!!!!!

Jordan and the guys did a great job with the installation of my furnace very professional and thorough in their work. I would highly recommend
