Black Diamond calls ahead and gives the name of the tech. Keo arrived within the first 10 minutes of my scheduled appointment even though the weather was bad. He used covers for his shoes. He was polite and explained about a worn part that needed replacing. Great Service as always.

Jesus and his supervisor went way above and beyond to handle a complicated situation.
Arlene - McHenry, IL
Jesus was very knowledgeable, courteous and polite . He explained everything fully and worked very fast. I feel he went beyond what was required to help determine some of the problems I encounter. The pricing appears to be competitive and I was very pleased with how quickly I was able to get an appointment.

Jesus and Tony did an excellent job of replacing our old water heater which was leaking out the bottom. They were courteous and professional in their work. Jesus answered all of our questions. They worked quickly and efficiently and left the area clean at the end of the job.

Black Diamond is always professional, courteous, and efficient whenever they come to our home for service. We have used Black Diamond for plumbing and electrical and every experience is great. My last call with Jesus was very pleasant, as usual! The prices are fair and scheduling is amazing! I usually get an appointment next day if requested which from my past experiences with other companies is unheard of. It is nice to know that after hour services are available in the event of an emergency as well. If you are looking for a reliable company that provides great customer service, call Black Diamond.

We have been members of the Black Diamond Crystal Service Agreement for 5 years. They come and service our HVAC twice a year as part of the agreement. Plus we get discounted prices if parts are required. And 24 hour / 365 day service availability at a very reasonable price. Who could ask for more!
Topper - McHenry, IL
Showing up early and upon helping out with trying to trouble shoot an problem, we learned that our Electrical main had some serious issues including 27 recalled breakers and illegal grounding lines. So we moved forward with replacing the whole thing. The hard part was shutting down the house for close to 5 hours. But it went perfect. Thank you.
