Chris is the best technician that has ever come to service my a/c / heater since 2012. Professional, respectful, courteous and definitely the most knowledgeable I've had come into my home. He is the only tech to wear his shoe covers since 2012!!! Chris was at my house until 9:30! He could have cut a few corners to get done earlier, but he stayed and completed the spring check up! From now now I want Chris to be sent to my home!!!
