“Diamondback has helped us in a pinch on several occasions. We have also contracted them for several electrical jobs for our company. Quick and friendly service, we highly recommend Diamondback for all of your AC or electrical needs!”

“Dylan arrived 2 hours early. He gave recommendations but didn’t push any up sales. Our system is very old (26 yrs), so the repairs he recommended would only be a bandaid if parts were still available. Honest, straight to the point and knowledgeable. Wish all companies would follow suit, highly recommended.”
