Rick was great. He was professional and explained, what he will be doing, what might need to be done and how much it will cost, before he moved forward. Trying to work out the best price. All my experiences with Black Diamond are positive.

Jim did the whole thing by himself-install new ac. He worked hard, was friendly, courteous and, with the countless times he had to go in and out, he put the booties on every single time. His work looks nice and its keeping my house cool.
