Black Diamond had always been prompt, courteous, and professional. We have used them for fixes and emergency repairs. We recently started using them for our seasonal maintenance for our HVAC. Service is second-to-none and the value is unbeatable. Whether you need an emergency handled or just regular service, Black Diamond should be your first, and only, call.
Black Diamond was here within an hour. Scott Jensen was the tech. Could not have been a better experience. He was courteous and knowledgeable. He had my AC going within an hour. And walked me through everything. What a great company and employee. Price was better than quoted from other places by hundreds. Definitely recommend Black Diamond.
Mike C. and Black Diamond did a phenomenal job at a fair price for our non-working AC. Got it up and running in an hour! Also fixed a rattling sound that we hadn’t even mentioned. Far less expensive and far more responsive than the “big names” you see on TV, one of which screwed up several things with our heating and AC. Never going back to the big companies that spend all their money on ads. I’d rather see the technicians get well paid for their excellent work.
