I had a little AC leak which cause the unit to stop working. I had Ozzy come by on time and prompt. He was quick to diagnose the issue, had some recommendations, and trusted his advice. Ozzy understood my dilemma with having to pick up the kiddos at a certain time and he was able to complete the job in time for me to pick them up. Ozzy did such a great that we'll be requesting his service in the future. Total cost was reasonable as well. So happy we diced to go with Blue Diamond!!!
