I had a problem with my AC unit on Memorial Day 2013. I called four companies of which one was completely booked and three others had a day off. When I called Luis he assured me that he would be at my place ASAP. About 25 - 30 minutes later he was taking care of my problem! Very professional, well equipped, detail oriented, very friendly. My dying AC unit was diagnosed, recharged, sealed, washed and put back into operation within about 35 - 40 minutes. What started as a disaster on a hot Memorial Day he turned into a routine maintenance. I was very happy with the service and I would recommend Luis to anyone!
