Today Jose A. visited my home and did the annual furnace Clean & Check, wow what a professional, he was extremely articulate and explained what he was going to do clean the burner check the exchanger and etc. He did not mined at all when I asked to observe. He willingly answer all of my questions and went about his job in a very professional way, I felt my furnace was in "good Hands". If I had a service company I would not allow him to service, but train my tech, we all need someone like Jose to lead. Thank you Bill Henderson 3801 Willow View Drive Lake in the Hills, IL
