    Hi guys. Have an older Heil condenser with a fried compressor. Model of the unit is NCABA59AB02 and 867.811171 and 3C459A.

    Anyone know what size this is, and possibly how old? TIA!

    5 ton, probably the old 8 SEER Villager series from the 80s sometime.

    Thanks Baldie. Ducts add up to 1680 CFM so I think I'm looking at doing a new 4 ton/new coil, instead of trying to ram 5 tons of air..what do you think?

    Good idea. 5 ton units are not too happy if you only give them 4 tons of air. In Colorado, we need about 450 cfm per ton to get the job done.
