I called at 0900 and the technician was at my home by 1400. They even called and asked if he could come earlier at 1200 but I was at work and had to do 1400. He still got there early, and had it fixed in 15 minutes. Then asked me if he could change my filters for me; no charge to me. The whole experience was just refreshing. The office was so polite and accommodating over the phone, updated via email of my appointment and when the technician was on the way, and then quickly got a bill. No extra charges or surprises. Will definitely be going with them in the future.
