I met with my dealer today to go over the final specs for a Goodman GMV90905DXA 2 stage variable furnace with a CLQ30-1 AC unit. He is suggesting an ADP cased coil with TXV for the coil instead of the Goodman CAPX061D2A. Is this an exceptable substitution? He called his distributor from my home and was told that they do not stock Goodman coils and all of his dealers use the ADP coils. He will special order it if I insist. Should I? Any advantages oneway or another? I'm assuming someone at the distributer (or is it Goodman or ADP) makes sure that the right coil is selected to get maximum performance and efficieny.
