"The yearly service agreement I have for inspection of my furnace and central air was a great investment. Jim a furnace tech arrived today on time per great communication with him and his office. The inspection was far greater than I expected for the cost. The tech was pleasant and very good at his job. Being a retired field service technician I’m a good judge and was more than satisfied. I highly recommend Kettle moraine as over the years we have had them replace the furnace and also our central air. Every experience has been a pleasure and without one complaint."

"Bob and his team were very professional. They arrived at my residence on time and spent more time than expected due to a need to replace the existing PVC venting pipe to a larger diameter. Overall I am very happy with the service performed by Bob's team. I definitely recommend his team to whoever needs heating and cooling service."

"Shane was able to schedule a prompt appointment. He arrived on time and performed a thorough diagnostic on the furnace. He identified an issue I was unaware of and corrected the problem with the air conditioner using parts that were still under warranty. I will gladly use his services again."

"I cannot say enough about our technician, Jordan, or the service of In Phase. We put our request into Angi and probably 1 minute later In Phase called. We have been wanting to upgrade our house to Ecobee since we purchased it two years ago. We thought we could do it ourselves, but our home had 3 zones, a two-wire boiler, and a newly added Central Air system. I had tried to hire other companies to do the job in the past, but very few companies were familiar with Ecobees. When In Phase called they were confident in the Ecobee system and were able to get us in the next day. Jordan showed up on time and was very personable and knowledgeable about the system. He had everything up and running in about 2.5 hours. This easily saved my husband and I a weekend of working on this, not to mention the fact that I didn't have to hear any cursing. (LOL!) BTW...we had already purchased everything, Jordan installed it and got it all set up for us. Many thanks!"

"Excellent service, very fast response to my request for service, picked up laptop, diagnosed issues. Initially thought it was an OS update issue but the hard drive had failed along with other components (including 'CPU). Because other components were involved, a new solid state hard drive was put into a laptop with a working processor - same type CPU as in the failed unit. The laptop was repaired and returned in less than a week. This company picked up and dropped off the laptop (driving from Huntsville, AL (about 60-70 minutes)-- great service in this covid environment. I would recommend this company to my family./friends and will use again."

"My old central air unit went out and Mike (the owner) gave a quick response to my service call. I decided to purchase new central air. Mike and his crew member did an excellent job with the new installation. They were very hardworking and it was done in no time. Mike goes the extra mile, is very professional, and wonderful to work with."
