Armstrong ULTRA 5 TECH 80, Model No. 45647-001 BTUs?
I have a 2,300 sq. ft. two story home with an Armstrong Air ULTRA 5 TECH 80, (Model No. 45647-001) furnace heating it. My wife and I think this furnace was in our house before the previous occupants added a large addition and that it under-powered to handle the size of the home. I have done some searching on the web regarding this furnace's specifications and have come up with next to nothing (other than people trying to figure out why it won't stay lit).
Does any one know the BTUs of this furnace? Also, I have read that it would be ideal for us to have a 140k - 150k BTU furnace for our home, is this true?
Thanks in advance!
