I called Scottsdale Air to repair a unit and provide annual maintenance. The tech came out to do the repair, which was handled well. He called the office to see if he could stay for the annual maintenance but the office needed him for other calls. He scheduled me for several days later, between 8 and noon. I took the day off and waited all morning for their arrival. At 1PM I still had no service, so I called the office. The woman who answered the phone said I was not on the schedule. She said she would reschedule me for another day. The office did not take responsibility for their error, blamed it on the tech, and did not offer me anything to compensate for the inconvenience such as a discount. I will not do business with them again.
