Unbelievable, Ken and his assistant went right down to the source of it, figured out this complicated little machine & fixed the problem. They went above & beyond any AC service that I have ever had. From my first call they communicated well, the guys were on time even gave advanced notice & sent a picture so I would know who was coming to my door. Ken went the extra mile to explain what the issues were, serviced, repaired & cleaned everything related to my AC. I would highly recommend Ken!!!!
