I am in Central Valley, Ca and it is very hot this time of year. This week is a scorcher. We survive with AC but do not run it at night. We have a whole house fan. Early in the mornings, we open up the house and, assuming it is cooler outside, turn that on and it sucks the cool air in and the warm air out the attic. When the temp is not going lower, we close up the house. It will usually stay comfortable until at least noon. Ceiling fans in every room. If we happen to get a Delta breeze, nice to sit on the patio in the evenings. Any errands that have to be done are done early morning. It is 106 today. Not going out today!!
