I have a old Whirlpool heat pump that has gone kaput. It was installed new in 1985. I need to replace it but the sun has bleached the specs label so that I can't figure out how many tons it is. The indoor blower section has the following markings:
Model: NAXD007AH02 (underneath this number is 867.823332)
Can any of you fine folks help me ID the tonnage on this thing?
