My home warranty company selected Blue Ox for my AC repair. The repairman arrived during the time window that I was given. He was professional and quickly diagnosed the problem and made the repair. My thermostat had failed. He then checked out the system to verify the repair and check that there was not another problem as well. I am very satisfied with the service.
The only part I found less than satisfactory was that it took a full 24 hours to hear from Blue Ox to set up the appointment after I called the home warranty company. It could be a delay by the home warranty company or with Blue Ox, I do not know which.
