My wife an I had Alaskan Air come and service our AC unit today in Tucson 7/19/19. Michael Rodriguez and his helper Marquez (sorry if I spelled that wrong) Did a excellent job. They were prompt on their arrival as well as professional in their presentation. They were extremely knowledgeable and answered all the questions I had. They were in and out in a little over a hour and did exactly everything they said they would do. I'm extremely happy with their service and would use them again for any AC issues I may have as well as recommend them to my friends and family.
