Same here. We've hit 79, but by then it's 78 outside. Outside, it's hit 89, but it was only 73-ish inside.
My definition of "get above" is when it gets above 80 around 3 pm with the likelyhood
of another five degrees. The early evening spike doesn't count. The walls and roof
start radiating inside most severely when the outside temps are sinking fast.
I've hooked up the water lines, cleaned it out, and put power to the fans
on the twin units. So far, I've been running the fans from the time the
outside temp < inside temp till about 3 am or so.
With the sun setting so far North of West, the swampers on the South
wall are in shade for an hour or so before sunset - making for decent
conditions for all the hooking and cleaning and stuff like that.
Leak checking has not taken place, but I put all new brass fittings on last year.

That shows you the value of good insulation.
The biggest bill we ever had in Chandler - with lots of times the temps were well over 110 - was $170 one July.
That was a big old 2650 sq ft house.
