We are hoping the circuit board will last longer than 3 years!! Can you offer a discount for services if we have multiple houses?

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.
