I was having problems with my A/C unit and a Diamondback service technician was at my home within hours. When the A/C problem persisted, the Diamondback Air owner appealed to the A/C manufacturer and I received a brand new unit...in my 35 plus years in AZ heat, I have never had a A/C company with such dedication to the customer. Too Bad, I am only allowed five stars, I'd give them More!
