Today we had the system running at a lower setting (75) since the early morning. The inside temperature dropped to the 75-76 range while outside temps remained at 98-99. My wife cooked a bit, TV on, doors open with kids coming in and out and the temp remained in the same range. Can the difference be the system was removing more humidity yesterday because the overnight setting was higher?

Yep. Let's take a square slab of concrete on the ground, say 50 x 50, which makes for 2,500 square feet, not an uncommon size for RNC today. Run up the walls evenly to nine feet, and slap a roof on. Now we have 25,000 cubic feet.

Let's take one wall of the lower height building and find its surface area: 450 square feet. Let's expose it to a temperature difference of 25 degrees between interior and exterior. 100 degrees outside, 75 degrees inside. No windows or doors. No sun beating on this wall...just a simple air temperature difference. Let's also give it a consistent R value of 19 (no thermal bridging or framing factor to worry about here). Total heat gain for this wall: 592 BTU.
Now run it on up to 26 feet, other parameters unchanged: 1,250 square feet at 1,645 BTU. Yikes.
But...but...we don't have to cool all that air...just the air in the occupied zone...right? So...you want to purposely trap a lot of air that you can't adequately condition for moisture, dust control, etc.?
- Electricity makes refrigeration happen.
- Refrigeration makes the HVAC psychrometric process happen.
- HVAC pyschrometrics is what makes indoor human comfort happen...IF the ducts AND the building envelope cooperate.
A building is NOT beautiful unless it is also comfortable.
and what type of insulation did you say you have in the
what types of windows? solar heat gain & ufactor numbers?
low e...argon? what types of frames?

best of luck.
