Outstanding Service, Knows His Stuff




Michael C. conducted an annual air conditioner check. We knew the unit was on its last legs, which he confirmed. (Bummer) However, Mike talked us through our options and helped us choose a new air conditioner unit, and arranged same-day installation. We believe it will last us for years! Thank you to Mike for his knowledgeable, friendly assist.

Very thorough job!




I appreciated the explanations made by the worker of what he was going to do and later of what he found to be the functioning level of our furnace and AC.


Prompt service.




Was scheduled between 10 and 12. We got a wake up call around 8:00 asking if they could come earlier. Raudel was pleasant . He knew what he needed to do and got right to work. He is an asset to your company.


Amazing




I love Black Diamond and Jim was amazing. I have a very disabled husband who had loosened our first floor toilet so much so, that I thought we were in big trouble. I was sure a major flood was next. Jim came and in a very calm voice assured me he could resolve the issue. He also suggested a special toilet seat that could greatly help. After the toilet was securely fastened to the floor, we immediately went out to purchase the special seat. My husband is so happy with his new seat and it has made such a difference, he can't stop praising Jim for all his knowledge. Thank you for making my day and my husbands life.


Great Service; Fast Response




The work was done professionally and quickly. The 2 gentlemen helped me with quoting 2 additional projects, one which was done at the same time. I thought the price was on the high end.


Reliable and polite service/ love the coupon





New furnace estimate




Mike was very informative, he made me feel very comfortable like a father would. He answered all of my questions and explained everything to my hubby over the phone.


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.
