Great service!





Great service!




We needed new kitchen pendent lights (due to crappy bulbs) and a ceiling fan that wasn't eligible for a universal remote. Rick was great from start to finish. He did an awesome job! We picked out new lights and a fan. He came back and did the install. He was careful and precise. He even offered a suggestion of a dimmer switch which helped with our new lighting. We will for sure use Black Diamond again for all our electrical. We previously have used Black Diamond for plumbing and have had no issues.


Great Service




Clay has been our serviceman since before joining Black Diamond. He is the reason Black Diamond is our HVAC company. He is a stellar representative of your company.

Raudel was very polite, courteous, knowledgeable and very professional. He solved my problem, and fixed the problem relating to work earlier from Dan's work and I would highly recommend him again for service.Dan did a great job also, and replaced and repaired a part with the hot water heater, I would highly recommend Dan again for service. They both are highly skilled in their work.


Dan was very polite, courteous, and professional. I was very pleased with his service.
