I am extremely impressed with PDQ mechanical. I had some issues with a service company my home warranty sent out. After 7 days with no air in AZ, I got fed up and called PDQ at 4:30 on a Thursday. Chase showed up at my house at 10am on Friday to fix the unit. He did a complete diagnosis and determined that the previous AC company was completely wrong and had the wrong parts on order. He fixed the wiring and replaced a capacitor he had on the truck. He was done quick and was very respectful of our house. I would strongly reccomend PDQ Mechanical.
