I would like to start off with Mr. William White the salesman and system evaluator. Made his appointment on time and put on footies to enter my house I was shocked. He assisted me in finding the best system for my money. The installers were the same professional courteous from beginning to end. I felt safe and secure the whole time they were there. Jon Wayne heating and A/c deserves all the credit for the way they train and hire the best of the best. I am truly happy and overwhelmed with this great system. FIVE STARS IS NOT enough! they deserve ten!!
