When we lived in PA, we heated with fuel oil and we bought it from Arentz Oil Service. They always had a reasonable price and delivered it whenever we needed it. If we had a problem with our furnace, they had knowledgeable service people to come out and fix it. When our old furnace up and died on us in the middle of winter one year, we called them and they sent their service department out to put a new one in and got us up and running the very next day! They are good people to deal with! I just thought I would pass this along to anyone who is using fuel oil to heat their house in south central PA!
