I called Miller Services and the owner sent a tech out on the same day to assess the problem. I received a call from the tech, who walked me through what the issue was and what he needed to do to fix it. A part was needed, so they received my approval to do the work and ordered the part the same day. Within a few days, I received an e-mail and a phone call to let me know that the part had arrived and that they could come by to do the repair when I was ready. I scheduled a day for the repair and the same tech came out at 8a.m. (when he said he would arrive) and had the new part installed within 30 minutes or so. The system works like new again. I have used Miller Services in the past for a new install, on another home as well and they have always been consistent with their response, their professionalism and their overall customer service. You can't go wrong dealing with Charles (the owner), Jo (at the front desk) or any of the technicians. I have dealt with a few other HVAC companies in the past and Miller Services beats them all by far in the Triad area.
