Friendly and professional

We blew a circuit in our living room and we called Black Diamond. We had no issues with service and we had our issue fixed quickly. Great job.

fast response

I was so thankful for the fast response and the ability to get my hot water heater replaced the same day I called. The dispatcher, Pat, was very friendly and helpful on the phone. She was able to set up payment over the phone, since I was calling from work to schedule my appointment. Jennifer called later to say she had a technician available even before our appointed time, which was great. I was not home, but my fater in law and son were and they told me how fast the technician was. When I got home, I was really pleased at how clean the area was where he had been working. As the cleaner, I really appreciated that ! The only thing I was upset about was that the t technician noticed the humidifier attachment was not up to code. I believe he mentioned this to my 19 year old son, and it was decided to go ahead and fix that so it was up to code and could be connected . The technician should have called me before going ahead, not taking the word of my 19 year old kid. So when rhw receipt came it was for significantly more than my quote of 1475. It was a significant amount more, at 1710. Not nice to find out after my card has already been charged. Not a nice surprise, felt like I had the wool pulled over my eyes. When I tried to contact someone to go over the charges, I only had a small window of availability to talk with the accounting department, and they failed to call me back. I was able to review the receipt online, a day later. I am very happy with the work that was done, but the technician should have called me about the unscheduled add on . It was a very expensive add on I was not expecting. I think my original quate for the hot water heater was excellent, not happy about not getting that extra call.
