HVAC technician Derrick was the best technician I have experienced in 30 years. He was on time, personable, polite and professional. Not only it took him only a minute to diagnose the problem of my A/C, but also he explained the problem and the mechanism of the parts that went bad to me in a way I understand. Then he told me what he was going to do, and how much it was going to cost. After he fixed it, he showed me the picture of what he put in, told me about the particular brand of the parts he put in, why that's good and what to expect in the future. He was so efficient that the A/C was back on in no time. Thank you, Derrick!
