Sounds pretty good to me.The saga continues. The A/C is cooling my new home but I can only get the temp down to 75 degrees on a 100 degree Texas day. I really appreciate it if you could help me answer some of my concerns below:
I doubt you need more cooling - might want to ensure that the ductwork is sealed/insulated, refrigerant charge is correct, and possibly possibly look into topping off the attic insulation. (Not sure what minimum code is there, but it would be wise to have R40-R-50)
"Green home" means nothing.
