Edit- I should have said there were additional factors besides cost of gas vs oil. Gas is a less expensive fuel, but I had other things to consider.Yeah, I guess gas is better. I did the math when it came time about five years ago to replace the furnace and believe it or not, it was less expensive to stay with oil for many reasons.
If you think about it, Baltimore generally doesn’t have cold winters. Couple of years ago was not a normal winter for us. Anyway, my thermostat stays at 65* and I’ve never worn wool socks since leaving Chicago many years ago.
