I live in the mountains in NC. I need to replace 20 year old heat pump. I have heard good things regarding an oil-pac, however, we can't seem to find anyone in this area that has ever installed an oil-pac. I currently have a heat pump with back up oil moniter heater, but during the winter I have to use a kerosene heater as well-any thoughts on what would be the best route to go? We are considering a heat pump with an oil furnace. Thanks!
