I was extremely please with Supreme Air's courtesy, professionalism, quick response, and subsequent follow-through from the initial call to the 24 hour hot line to the technician, Christopher, leaving. The call center was professional and courteous and the follow-up emails and text were timely and helpful in knowing when they would get here. The technician, Christopher, called about 20 minutes ahead of time which was followed-up with a text and email...very convenient. Christopher was quick, thorough, on-time, and professional. He diagnosed the issue in less then 5 minutes and was here less then 30 minutes.
