Fear Abated




James was professional, thorough and confident. His assurances and expert workmanship was impressive. The cost for the repair was reasonable. I will recommend Black Diamond to anyone in need of excellent work and reasonable prices.

Electrical headache - solved




Had a vexing electrical issue with two outlets and a ceiling light. Matt came in, began assessing the situation and isolated the issue. He was prepared, methodical, and professional. Precisely what was needed to solve my issues. Matt from Black Diamond did a masterful job. Thank you!

scheduling hassle.




Scheduling routine maintenance is difficult, and should not take 2-3 weeks to get done. Pre-pay for your services is a big (major) turn off for me. I do have confidence in the quality of your service and service people are great.

Never expected to have my water heater replaced that evening.


Panic Mode




I was in pure panic mode when I had an electrical issue at 5:30 am. Black Diamond to the rescue. The on call electrician lived miles away, but he responded as quickly as the traffic laws would allow. To top it off the electrician was pleasant and professional. There is no doubt in my mind I will be life time customer.


Extremely over priced




To replace 4 pieces of 3/4" copper piping. 2 90 degree elbows and 2 small pieces of straight pipe. The price was shameful. The technician was friendly and knowledgeable, but the cost was not in line with the work performed. Shame on me for not getting the quote up front. Lessoned learned


Great service!




Service received by Mike C. was amazing. Not only did he repair my air conditioner, he educated me along the way so I would know what to look for moving forward. Service was scheduled for late afternoon and they called to ask if he could come at 10:00 a.m. Thank you Mike for making my unpleasant circumstance of having no air such a pleasant experience during the repair process! I would HIGHLY recommend Black Diamond and Mike C. if you are in need of service work.


Excellent service.




Jose M was there on time at 7:00am. He explained everything and worked quickly and cleaned up everything when he was finished.
