We had a issue with our existing A/C unit. From the first technition who found our problem and explained our options, then Mike in sales who went over the cost of all our options, and to the crew of Dave, and Tom who installed our new equipment... It was a pleasure to have the Black Diamond team take care of us. If you want a job done right the first time Black Diamond is you answer. Highly recommend them, and we joined the "Crystal Club" Because we will use them for all our plumbing, Heating, A/C, and electrical needs in the future! Thank you all!
