My furnace was dead so I called Opie's One Hour Heating and Air. The furnace had blown a fuse. Opie's One Hour Heating and Air came out and replaced the fuse, and the furnace powered right back up. It was Opie's One Hour Heating and Air that installed the furnace originally. We've been using Opie's One Hour Heating and Air for about three or four years now and I have been very satisfied with their service. The technicians and staff at Opie's One Hour Heating and Air are prompt and courteous!
