@Threepio our rental management company sent people out to fix it. The problem is that the unit is too small for the size of the house. So we cranked it up to 80° and I have a portable AC in my room that I only use at night. Still, our bill is astronomical.
@DearAmbellina2113 My house is basically 2000sq ft. I keep the AC at 78 except for the hours of 3PM - 6PM when it cycles up to 81 (3-6 PM is the High Cost "on peak" hours of my SRP EZ3 plan). My bill for June was $287
