BC Express Inc Heating & Air Conditioning put in my whole system a few years ago and I have a maintenance contract with them. When I called for my annual checkup, the serviceman, Savas, arrived. He was knowledgeable, professional, and informative every step of the way. He explained exactly what he was doing. Savas was great! I hope I get him every year when I call for the annual check. In the meantime, I have already recommended BC Express Inc Heating & Air Conditioning to many others.
