I had an evaporator coil changed out in my air conditioner. The installers were friendly, informative, and very knowledgeable. I had to have a follow-up service due to the fact my house was outside the normal when it came to installations. They sent a technician out to my house on a Saturday within 2 hours of notifying them of the problem. The technician was able to diagnose and fix the problem on site. Overall excellent experience. Would definitely recommend Choate's!
