AC Repair




I called Black Diamond in the morning regarding my AC not working. They were able to schedule me in the same day. The technician, Nick, came out, quickly diagnosed the problem and fixed it on the spot. Extremely pleased with level of service from Black Diamond and Nick.

Another excellent job done well




Doug came to add some circuits at my office and install floodlights for the parking lot. I cannot comment enough how great it is to work with Black Diamond. Every one that I have come into contact with is nice, enthusiastic about their job, knowledgeable, polite, on time, does great work and is clean. I just love the work they do, and can't recommend them highly enough. I have heard people say that they are pricey, but they are comparable to other quotes I have gotten, and worth every penny.

Maintenance for A/C and furnace





Great Service




My water heater sprang a leak and I didn't notice it until late Friday afternoon. Called Black Diamond and Jorge was at my door in less than 1 1/2 hrs. He had everything on his truck it took to replace my gas water heater. Efficient, friendly service, if a little pricey. $1400 "out the door". Ouch! Good quick service. Showed up when they said they would. Job was well done. No complaints. I'll call them again.


Gerad

I always have had great experience with Black Diamond employee.


Excellent Work




Jared and Matt showed up promptly as always, and did a remarkable job running a dedicated electrical line to my copier. They left no mess, and the work was done in an unobtrusive manner. They showed me what they did when they were done, explaining thoroughly so that I could understand it. Just like I have come to expect from everyone at Black Diamond, they were prompt, polite, professional, neat, and just a joy to work with. I can whole-heartedly endorse and recommend Black Diamond!


Outstanding Service!




Tony and Jared came over to do an estimate for some electrical work. They were scheduled to be here between ten and 2, and arrived promptly at 10:00. They spent two and a half hours thoroughly investigating the situation, asking questions and explaining their findings and the estimate. The estimate was explained in person, then carefully written out and explained again. While they were there, they saw that one of my storm windows was flapping free in the wind, scattering glass around. They screwed the window shut, picked up the glass, and refused payment, since that's not what they were called for. They explained every single item on the estimate, as to why it was necessary, what it did, and why it cost what it did. Most importantly to me personally, they are enthusiastic about their work and have great attitudes. I've said it once and I'll say it again, Black Diamond is the only company I will call for my electrical and plumbing needs!


Extremely polite and professional





wonderful
