I have a slight concern and would think this forum can answer my question since you all have a lot of experience with furnaces.
My question is what size of furnace is required for a 1100 sq ft house with R12 walls (basement and upper level) and R40 in Attic it is a bungalow and the basement is completely finish with heating.
Heating main level and basement, basement have cold air return vents and all rooms in main level.
I am in the process of selecting a GMVC95 - 0704
Hi-fire output: 67k Btu
Lo-fire output: 47k Btu.
This is a multi-position, two-stage, Variable speed gas furnace.
What do you think?
Any help, comments would be appreciated.
