I got a couple quotes and different opinions on sizing for new furnaces. I am replacing 2x25 year old 90,000 btu lennox furnaces.
I am looking at 2 95% efficient furnaces with ECM motors.
My house has the upstairs which is 850 sq ft, the main is 950 sq ft
one furnace runs the upstairs the other runs the main floor and 2 vents in the basement. (not need much heat down there)
one quote said a armstrong air 90,000 for main floor and a 70,000 for upper.
the other quote said 2x 60,000 goodman furnaces. and told me a 90,000 is way to much for the size of the house.
Can anyone chime in and let me know what they feel would be good sizing for the 95% efficiency furnaces for the sizes of my house.
