HI, I am building a new home (3600 sq ft without the basement). Chicago Suburbs. The house will have a basement, first, second floor and an attic. It will have two furnaces. One will be in the basement and one in the attic.
How can I ensure the right size and specifications of the furnaces?
My GC is offering 80, 000 BTU 92% American Standard in the basement and 60, 000 BTU 92% American Standard in the attic. Also two American Standards 13 seer A/C units.
Do you think these will be enough? Should I upgrade to Trane?
Please, help. So hard to navigate through all the specs.
