I can not tell you how grateful I am for Dave! I noticed mid day today (Sunday) that something was wrong with my air conditioning. It was getting hot in my home way too fast. I called Dave and he was here within 90 minutes and had my air running less than 10 minutes later. Plus, it only cost me a very low trip charge since it was an easy fix. Air conditioning is life in AZ and I'm so happy to get mine back. Dave is my new A/C guy forever!
