Opie's One Hour Heating and Air has done a lot of work for us over the years. A few years ago they put in a new air conditioner. This year they installed a new furnace. I usually get the same guy who comes to the house and he knows the systems and where everything is. We also have a maintenance contract with Opie's One Hour Heating and Air so they come out twice a year to check on everything and provide any necessary maintenance or repairs. The new furnace keeps the house warm. That makes me happy!
