Oustanding Service




Doug was very professional. He listened to our needs and advised a solution. The price was very fair and we decided to have the work done. Doug did a great job and cleaned up after completing the work. We are very pleased and would recommend Doug and Black Diamond to anyone.

Great Service - Really pleasant and helpful technician.




The technician who came out to help with my broken furnace was very helpful, prompt and pleasant. He was very knowledgeable and quickly diagnosed and fixed the problem. His service was great. My only issue was the cost of the parts. Bryant seems to have gone overboard on the strategy to make money on repair parts. A similar part on a comparable furnace would have been significantly cheaper.

Great Service!




Josh was great. He took care of the problem. Unfortunately, there are some chemical drops the drip onto our hardwood floor. The drippings can't be clean with any cleaner as it seep into the wood. Notified Josh of the problem and he came to fix it. He told us that he will notify his supervisor but have not heard from the supervisor. it's been over two weeks.

Service




Everyone over the phone was helpful. The first installer was great and was adamant about making sure the area looked as if he was never there. I did look at the install later that night and was not happy with the position of the gas line. I called black diamond and they offered to have someone out that evening but I insisted tomorrow morning would work. They showed up the next morning at the exact time they said they would arrive. Discussed with the tech what concerns I had. He provided a solution and got to work. A couple hours later the work was done mitigating any concerns I had previously. The 1st installer did walk me through the work that was performed and I signed off on it. What made this exceptional service was that I called later that night after looking at it again and Black Diamond was adamant about getting this fixed right away with no push back.


Great service




Got the work done in a timely manner.


Oustanding Service




Service Technicians arrived to quote on a air register extension. They were able to go get the required parts and returned within an hour to do the work.


Very friendly and polite servicemen




This was the third repair call on my two-year old furnace. The two repairen were here until 7:30 PM. They were very polite and informed me what they were doing.


Home owner





Great sales and installation staff...... We got what we needed. Thanks.




Furnace quit after 27 years, and they delivered quickly. Sales staff came out the same day....... Installation a couple of days later. The installation crew were on time, and neat and tidy workers. No complaints.....
