I had another company come in to fix my Furnace/AC problem. It took them two weeks and still they could not do it. Frustrated, I needed to talk to someone I could trust and found Bill's company and read the reviews. Two days later Bill himself came in, diagnosed the problem, fixed it and provided me with future advice. I found Bill to be very knowledgeable and honest. Thanks Bill. Advice I will now share with you: get your HVAC checked every year.
