Best heating & air service we've ever experienced! They quickly diagnosed & fixed our problem. Other service people in the past just tried to sell us a new system instead of doing repairs. Black Diamond pros are honest & skilled. We will call nobody but them in the future!

WOW!! I can't say enough about Mike Brown and his team. They were absolutely amazing and extremely helpful. My mom's AC & Heater needed to be completely redone and after seeing about 8 other companies we finally entrusted Black Diamond Heating & Air with the job. BEST CHOICE EVER! They came out and were totally professional, warm, & it felt like we were talking with a friend. They were straightforward and honest. They explained everything they did throughout the job, answered any questions we had, and went above and beyond to make us feel comfortable. IT's so nice that people like this still exist in the world. Ethical, Honest, Family-Owned, Local, & Truly Wonderful. I will definitely recommend to everyone I know that they are the place to go for any heating & air needs! Thank you so much Mike Brown & your incredible team!! 🙂
