Great customer service from the first phone call. I have a business in CL and hear your commercials on Star 105. Everything you advertise is spot on!

Impressed

I was very impressed with the staff and Black Diamond. Had several issues with a furnace install and they stuck with it til all issues resolved. Kyle, Alex, Oscar, and all the rest I dealt with were very pleasant and patient and took care of any and all issues. They were neat, and cleaned up after the jobs were done. Will for sure use them again. CLH
