I'm not sure how much this will help as it is somewhat general. I have no trouble keeping my 3 tanks at 78F year round, my 8 gal is 76F, it probably could drop another degree or 2 with evaporation. It has Cherry Shrimp in it, they seem to fine. That being said, I'm a total noob when it comes to shrimp.
You are not going to want to ever shut off your A/C anyway- my place is around 78 daytime, 75 night.

Your AC unit does not have to run as hard either as it would cooling down a hot house."

"I've lived in LV for many years and kept an aquarium (with varying success) for about 10. I totally agree with the above. As it was explained to me, after a few hours, everything in your house is 88, 90 or whatever, not just the air. So you have to cool not just the air in the house but all the warm "everything" else as well. Bump it up maybe 2-3 degrees if you want. Mine is programmed to go up a couple when I go to work and down a couple when I go to bed."
Here in Denver it's hot in the summer (mid 90's most days) and without a chiller it's hard to keep the tanks at 80 degrees. I can definitely tell that the neo shrimp slow down their breeding a lot when it's hot, but they otherwise seem to be ok.
