Look into it. best bet is to go with the 2 stage cva 90000 with 4 ton unit and coil with infinity stat--you get federal and manufacturer sal tho save about 2500 there so far.

I kinda touched on this equipment before, but I am interested in hearing opinions on the following tradeoffs.
I think I'll be going with the 4 ton 24APA7, but which matchup is better advised?
...the 5 ton CNPHP coil and the 110K 58CVA furnace, which achieves 17 SEER and 13.5 EER? (Better efficiency due to bigger coil.)
...or the 4 ton CNPNP coil and the 90K 58CVA furnace, which achieves 16 SEER and 13 EER? (Better balance of furnace size to need.)
I'm in Texas and 80-90% of our energy cost is cooling.
I realize that the 110K furnace is more heat than I need, (heck, even 90K might be considered too big), but I'm wondering if the additional 1 SEER point and 0.5 EER point would help me with utility costs in the summer months more than the detriment of being oversized in heating?
I'm currently running 115K single-stage, which is WAY oversized. At least the 58CVA is two-stage.
