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!
Black Diamond has been my go-to for HVAC services for years. Very satisfied.
Knowledgeable, friendly, and does a great job! Will definitely use again !
David did a fantastic job.
You guys did a great job! This was a lot of work but you guys tackled it!
Black Diamond and Dave provide excellent service. Quality Workmanship and explained every detail from start to finish...
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
He was on time. He was very helpful. Explained everything. He was done in an hour I would use them again. Great pricing
