Had Black Diamond out to the house twice in one weekend; plumbing problem and then again for a ceiling fan install. Black Diamond employees are always courteous, neat and go beyond. I also appreciate the fact that they warranty their work !

Reviewing how great Black Diamond's service is, is almost boring. Yes, they were prompt, professional, polite, neat, and thorough. *yawn* What else is new? Seriously, they are great, and I call them for everything.

Great service, Vert thorough

AC Repair

WILLIAM from Marengo, IL

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.

Great service as always

Another excellent job done well

Paula Rieghns from Marengo, IL

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.

Great Service

KEVIN from Marengo, IL

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.
