This company was professional, urgent, and helped find the most efficient way to fix our AC issue. They were kind and made it their priority to come out that same day I called. They will be our GO TO for the future.


5 stars service every time. Darryl came out same day within 2 hours from when I called, diagnosed the situation and had me up and running again in a 1 hour and a half. Very quick! Can’t say enough good things about the quality of service that was provided. If the time comes and I have issues I will not hesitate to give DiamondBack a call again. Thanks again very much appreciated. God bless y’all. Keep up the good work.
