Damyon was knowledgeable and very friendly. He fixed our problem on a very old unit, and we now have cool air again!! Yay!! Yes, I would recommend him as a technician to other people.
Was having some thermostat issues. Dylan came out and ended up replacing it. No questions. Time will determine if this solves this. Looking good so far.

Very friendly and easy to work with from the first visit until installation of our new AC. It was time to replace our 17 year old unit and Kettle Moraine provided us with multiple options - installed our choice quickly and fixed several issues created by the original AC. Very professional, on time (actually installed the unit two days early!) and a pleasure to work with. Highly recommended!
