My AC went out halfway through a super hot East county day. Brian still came by after hours and was absolutely amazing. He was open and honest and took the time to explain not only what was wrong but why it went bad and how to repair for the long term. You have a customer for life. Thank you Blue Diamond for saving us from having to go to a hotel!!!!!
