Exceptional weekend service! It is difficult to find a good A/C repairman, especially one who can work on the weekend.The technician who came to service my A/C unit, David C, was polite & extremely professional. He diagnosed the problem immediately and explained everything so that I had a better understanding of the issues with the unit and what he was doing to address each one. I am very pleased with the service that was provided to my unit by David C. & Cool Air USA.
