No A/C so surviving with lots of fans (2 oscillating, 2 box, one small window and one celing fan in bedroom. Our house is quad level so I have dehumidifier on in basement and actually the family room isn't too bad-all blinds shut and windows aren't open so doesn't get above upper 70's. The bedrooms on top level are hot though. We don't have ductwork for central A/C and we have casement windows so window units are for the most part not practical. the cats spend lots of time outside or laying on the cement floor of the garage.
