Rated 4.9 out of 5 stars based on 108 customer reviews

Courteous, friendly, efficient. Great experience.

So willing to help me understand what was needed to fix my AC issues. The two gentlemen noticed a tire nearly flat on my car as they left and were kind enough to put air in it for me. Since I am older and unable to do this on my own, I was so appreciative of this. These gentlemen went above and beyond what was expected of them. They are truly an asset to the company and their profession. Jerilyn

Great service

Gerad was wonderful. He installed much needed new smoke alarms along with taking time to answer my questions about other things around the house. He has me hooked on Black Diamond. Thank you very much Gerad.

Blk Diamond is the BEST!

Always have good experiences with all people associated with Black Diamond from the folks who answer the phone to the techs who come to the house. We've had HVAC, plumbers and electricians out over the years, they are always very professional, courteous and knowledgeable. There is no one else we would call!

Electrical Excellence

The team came to install multiple electrical outlets in our house. This was no easy task as they were going in places which required going through and around studs. The guys did an excellent job of making recommendations, installation the outlets, then went above and beyond and hung the wall mounts and mounted the TV;s and hooked up all the gaming devices etc. I have used Black Diamond for many different electrical and plumbing needs, and they have always been top notch!!!
