I have been using One Hour Heating and Air - Bethel Park, PA six or seven times over the years. Their pricing seems quite fair for the quality of work that they do. I really appreciate that the company responds quickly when you give them a call. The other day, I called them around several or eight AM in the morning and they had someone out here by noon! The technicians are always very knowledgeable and courteous. The furnace recently was not staying on and the flame sensor apparently was dirty. It was a quick fix by the technician who came. Like the other technicians, he was very good. I recommend these guys to everyone.
