Josh from Premier Service came to service my AC unit after the prior company, Blue Ox had come out and failed to diagnose any problems.
Their customer support was very flexible in scheduling the service, and even provided me a "heads up" call 30 min before so that I could meet them at home instead of using paid time off from work to wait at home in a hot house.
He quickly diagnosed and repaired a bad motor fan. I would recommend this company to anyone looking for a good AC repair guy!
