    Are you sure you have the coil model numbers right.

    I can find cap coil ratings, not cnp.

    How many times must one fix something before it is fixed?

    Here's what I found from the ARI site, www.ARIDirectory.org :

    24APA518, CNPV*2417, 58MV(not C)B040:
    ARI# 1031793. 13.2 EER, 16 SEER

    24APA542, CNPV*4221, 58MV(not X)B080-20:
    ARI#1390282. 12.55 EER, 15 SEER

    No info on 24APA560.

    Good luck.

    Does the furnace make a difference?

    I used the attachment above, it was helpful, except that the furnace was not listed. gary_g came back with real numbers which was great. The issue may be that the furnace are comfort series and the a/c and coil are performance series.

    Thanks to all of you. garyg, dansw, and beenthere.

    Sorry this doesn't have to do with your question of the SEER/EER numbers, but it is important.

    10 tons of cooling for our (MD/DC) area seems excessive. Did you make sure the contractor did a heat load calculation to determine proper sizing? My home is ~2500 sq. ft. and has 3.5 tons of cooling. I don't know what area you are in particularly though, so I can't envision the relative size of the homes.

    Home is likely ( ?) 7,000 square feet ( ~ 3 x normal)

    I would contact Carrier directly and have them provide ARI#s for the system matches that are proposed.

    Best to you.

    I will contact carrier

    dan_sw is correct, its over 7,000 sqft finished on 4 levels. I will contact carrier as suggested by gary_g. I had not thought of that.

    The only response I had gotten from the contractor was that it was at least 14 each zone.

    Again thanks.
