My tall and large house doesn't have central air. I do have a small (5000btu) window unit in the bedroom of the first floor and run it only on hot days, during the afternoon, I shut it off when I go to bed, the bed room usually stays cool if the sun isn't beating on the west side of the house (where the bedroom is). It removes the humidity, that's really all I need, along with ceiling fans...that room has a tall ceiling (the first floor of this house has several rooms with various height ceilings). The wall thermometer on the other side of the house usually shows 80 or 81 on a real hot day.Probably feeling the reduced indoor humidity more than 20 degrees. No geothermal here, indoor temp at 74 and July electric was $128. After paying SoCal electric rates that's next to nothing.
My House size/height is a big plus for living without central Air. The second floor gets hotter of course, I just avoid going up there on hot days. The Attic (3rd floor) has insulation in the floor and a tall ceiling and steep Hip Roof with two window dormers, It's a large space with probably more cubic air space than the second floor, and is well vented...but Dang it gets HOT up there on a sunny calm day...BUT all that keeps the first floor from getting overly HOT.
