I called the Jon Wayne office on Labor Day when I noticed the air coming out of the vents was warm. They were out early the next morning. Jacob, the service tech, was very friendly and was able to explain the approx 7 options that were available to me. The work was done by early afternoon. Jacob showed me exactly what he had done to the ac unit. The warranty that Jon Wayne has is unparalleled. I highly recommend the service and value Jon Wayne offers.
