Steve, my tech was professional, courteous, and friendly. While at the house, he inspected my AC unit inside the house, and the heat exchanger on the outside. He checked the furnace/AC electrically, inspected the condition of the unit (furnace was installed recently by you guys this last winter), and checked the condition of the heat exchanger and the pressure readings in the system. All in all, I'm pretty confident that he knew what he was doing, and that he was thorough in his inspection. I was initially a little nervous about the inspection, as I expected him to just outright try and sell me a new system, but your tech looked at everything, gave me an honest opinion of it's serviceability, and left with a handshake. I'm impressed.
