It was 109* F here yesterday.

My upstairs unit could only keep it down to 76.

Texas!

R50 in the attic, and a radiant barrier is the answer. unless you want to add a window AC for the hottest days. the expensive way is to change out your central AC for one with a thermostatic expansion valve, a variable speed blower, and at least a 2 speed compressor, a stepper motor compressor would be ideal. and have the unit oversized to handle those hot days.

109 here in Irving too. Our upstairs stays 74 and downstairs 72 during even those days.
