Pete and Tucker were right on time, left my basement clean and answered all my questions till there were no more to ask. Very patient.Job budding from Kettle Moraine is the reason we went with KM. Scott gave me a Furnace 101 class so I knew what I was buying and spoke highly of the team of installers at KM.So glad we went with them! Well worth the value!

Had Kettle Moraine Heating and Air Conditioning out to my townhouse for a furnace check before winter. Also just to make sure it is in working condition because I know it’s old. Brent did an amazing job! He never made me feel pressured to buy a new furnace but did tell me it’s past its prime. He gave me prices for new furnace and AC and we scheduled to have them come out beginning of Dec! Definitely glad I picked them!!

I am working on a remodeling project in which I needed my cold air returns rerouted to different walls so that I can remove a pantry. After receiving an estimate, I scheduled an appointment to have the job done. Kevin and Mike from Kettle Moraine Heating and Air came out early in the morning and completed a job quickly and efficiently. They finished faster than I expected and didn’t leave a mess for me to clean up. They were polite and took the time to address any concerns that I had. After inspecting the job that they did, I saw that they completed it in a fashion that shows their years of experience and their level of expertise. As a homeowner, I couldn’t expect more.
