“After a recent storm, our AC was having issues with blowing air but not cooling. Called Diamondback and got on the schedule for the next day for a tech to come take a look. James came out, he was very knowledgeable and assessed the problem and got us all fixed up quickly. He was professional and timely and did a great job, we all slept like babies that night in a nice cool house!”

Kelli B

“Both of my mini-split AC units stopped working properly at the same time. Not tolerating heat well and knowing we still had days of 90+ temperatures, I panicked. I looked up who to call and discovered Diamondback Air Conditioning had great reviews. I called and begged for someone to come today. Well, he did! He honestly told me it only needed Freon and after adding it to both units, they began cooling immediately. I can’t be happier! I highly recommend for quality of work, timeliness, professionalism, courtesy, and all other positive words!”

I called and got a friendly and prompt response. They listened to our problem and current situation and we’re accommodating to both! The technician was very polite and professional! He was up front with us about the situation and the cost and wasn’t pushy about what we should do. He gave us the information and let us make our own decision. We will definitely use them again!”
