I have a 1780 sqft home (1960s) in Lakewood single story home that needs a new furnace. I am questioning whether or not I need a dual stage furnace for my home. The house has no insulation, and with the current single stage 80000btu furnace seems to work ok. It heats the house fine, its just noisy (have to turn up the volume on the tv when it runs) and the ducting is leaking. Thats the reason for replacement.
I read this page and it may seem that I might be just wasting money going for the 2 stage furnace. Do you think that the smaller burner of the dual stage is not even adequate for my home size? After reading that page above, it seems that the smaller burner might not even have enough flow to get to the whole house. What do most houses in my area use?
THanks. Have a good day.
