My heating unit went out on a weekend and I was extremely cold and out of sorts. I called Jon Wayne, they sent technicians to address the problem. The service was done promptly, efficiently, and correctly. They did more for me than I expected or asked. They were considerate and thoughtful. Everything they did was explained fully and I was shown the parts that needed replacement and told why. I must say there is no one who would have given the service they did when I needed it the most. I can say that they deserve the highest recommendation which I would give them without hesitation.
