My A/C stopped cooling, the fan was going but it was blowing hot air. A friend recommended Dean Gartman and so we gave him a try. Dean was very courteous and really knowledgeable. He quickly figured out there was a leak, and that's why it wasn't cooling. On top of that apparently the outside fan system was really dirty and needed a cleaning. He cleaned up the system, and fixed the leak and added more coolant. He was in and out in about an hour, if not less. A little pricey in my opinion, but overall a good job.
