Black Diamond Electrical, Plumbing and HVAC has serviced our home at least a dozen times on various projects, some custom and some routine. In each service call the Black Diamond employee/s arrived on time if not early and prepared to work. The employees consistently are knowledgeable and share their findings and ideas for solutions if needed. Some of our projects have been rather unique and in every instance the Black Diamond crews come through with outstanding results. This said we highly recommend their service to anyone.
