I would much appreciate it if somebody could give me a rough sq" start size for the return & supply of a 60,000 output BTU Yok direct vent furnace. Model# P2UDD10N05701C Serial# ELCMS15607. 2 1/2 ton blower 1,000 cfm. It's about 10 years old. Most of my experiance is commercial. & I'm presently exhausted - to many hours - to much driving.
This furnace supplies a 1,000 sq ft. first floor & 1,000 sq. ft. basement 95% below grade.
It's a family thing.
Thank you very much
