I live in the Chicago suburbs and am looking to have a 95+ furnace installed. I currently have a 125K BTU Janitrol that's around 19 years old (standing pilot).
I've had 4 reputable contractors give me quotes on the Goodman 2-stage 95. Two guys say I can get by with the 90K and the other two say I need 115K. I've asked all 4 to do a load calc to no avail. And three guys eventually changed their mind when I questioned the size.
Anyone have thoughts which makes more sense? I live in a typical 2-story (2400 sq ft) w basement. This shouldn't be so complicated, right?
