Yes, you are no doubt correct that my furnace is not very efficient and a new one would reduce my heating gas cost. However, I have been advised that I should keep my old furnace as long as it works. The new fancy ones cause much more trouble and can eat up the fuel savings in repair and maintenance costs. That does not mean we are not thinking seriously of an upgrade. The house was built in 1981 so the furnace is 26 years old. I would really like to do groundsource heat pump but that is expensive to install and we lack the ground space to do it traditionally. The holes would need to be deeper and we would use fewer of them. The other alternative is a new furnace and ac unit but I keep hoping that they get better all the time and the bugs get worked out so hope that waiting is an advantage rather than a mistake. Also think of going total electric as we have lots of hydro electric power and the rates are reasonable. Would require an upgrade on the main panel. Also think about superinsulating the house but then wonder if I were going to do that if it would make more sense to sell and build a new one. Too many options so for the moment, I am doing nothing as the natural gas prices seem to have flattened out and are not yet breakng us.

The new condensing furnaces (two heat exchangers, PVC exhaust) are up to 95% efficient, ones with just an exhaust fan are around 80%, and I think the draft furnaces are around 60%.
