My central AC unit was not cooling properly. Shane came to my house and diagnosed the problem in minutes. He gave my system a boost charge to keep me cool until he returned as planned in a couple of days. He replaced a leaky dryer on the outside, charged my system and checked the whole HVAC system out for proper operation. AC is been working great! I consider Air Design a top notch company. Their customer service is always courteous and appointments are easy to get 24/7. And, good job Shane.
