What Our Customers Say
Brian did a great job. He was very friendly and professional.
Khamya did a great job. Efficient and very friendly. She loved meeting my dog. I hope she comes to do our AC check up!!
Kettle Moraine is my go-to heating and ac company after we needed both our ac unit and heater replaced two winters ago. We got a handful of quotes and payment options and theirs was by far the best and the service was amazing. Their team is so nice from point of sale to installation and maintenance. Paul, our maintenance technician today for our humidifier was awesome. Wore shoe covers once he came in, was a nice, down to earth guy and he did a great job. Highly recommend.
Provided info on the condition and efficiency of the furnace.👍
After researching tankless natural gas water heaters, I was glad to find out that Kettle Moraine Plumbing installs condensing Rinnai units with pumps that circulate hot water based on AI monitoring of household usage patterns throughout the week. Hot water is available on demand, even in remote areas of the home, during designated periods of use. I recommend the quiet 199 BTU unit that Master Plumber Dave T. recently installed as a retrofit to replace a very old 50-gallon tank water heater. Clean installation indeed!
Once again, superior service. Repair done promptly and as promised.
Matt and his Team contacted me in advance of their arrival regarding my HVAC replacement. They arrived on time as a crew of 5. They worked with efficiency, and despite the subzero outside, the temperature in my home did not drop 10 degrees. The team removed all debris and Matt instructed us about the new HVAC system and the WiFi thermostat connection. Superb work, courtesy and professionalism. Well Done!
Efficient and friendly.
The team came to replace our furnace they worked so well together and quiet. You didn’t even know that they were there. They finished everything in one day before 4pm. The men were experienced & very patient with me answering all my questions. I would use them again.. thanks Kettle Heating!
JJ was very professional, knowledgeable and courteous.
Our furnace was scheduled for a tune up. Patrick Gorman was our tech that handled everything from reminding us about them coming to going over what he did while he was here. Thanks Patrick again for your professionalism and your kindness. Greg H.

My go to place for heating/AC service. They do all my maintenance checkups and are very thorough. I recommend getting on the seasonal tune-up plan for piece of mind.
