Called SnowBird at about noon and told them my air conditioner did not seem to be working right. After answering a couple of questions regarding the unit, I was told that they would send a tech to look at it as soon as they could. Told me to expect someone in a couple of hours. Greg Allen came at about 2 PM, he had a good appearance. He proceeded to check out the AC unit and tested a circuit board that he said failed. He replaced this board and the unit worked. I was pleased with Greg and the work he did. Service was under warranty.
