Our street is getting a natural gas line and so now I have a choice of converting or just keep my oil furnace. Have any of you converted, and if so was it worth it? Our furnace is about 30 years old and needs some serious servicing, but we don't use a lot of oil, only about $700 for the past 6 months. The natural gas company said it will cost about $850 for them to run the line from the street to our house, but then we still need to pay somebody else to install the new furnace and get rid of the oil tank, and I don't have any idea how much that'll be. Opinions and ideas welcome, thank you ahead of time.
