Best A/C Preventive Maintenance in Phoenix AZ

Very rude. Refused to rekey a door lock and would not tell me why. They said they could do it on the phone the day before. Made the drive through traffic to get there only to be refused service. Wouldn’t even tell me why. He kept saying “I will not help you.” I asked why but he said “I don’t have to tell you. I will not help you.”
