I finally decided it's time to junk my old (40+ year old furnace) and get one of the best I can. I was thinking of either a Lennox or Trane, but really don't know much about either, other than they are well known.
My present furnace is 130,000 btu, and my last 3 gas bills were $450, $665 and $535. My home was built in 1925 and is not insulated (other than the kitchen and bath, that I remodeled) so I don't know how much a new furnace would actually help (but sure can't hurt I guess)
I aslo wasnt to add central air, but am not sure how well it would even work in this old house, with floor registers.
Any suggestions on brands/models, or what to avoid?
I'll more than likely wait until spring to get this work done. What should I expect to pay? Is $4,000 high, or about right?
