Out here in the desert, we use swamp coolers. They are not very effective when the outside temperature is above 93 degrees. The past few days we’ve flirted with 100 degrees. That is very hot — even with 15% humidity. The swamp cooler in my townhouse has a single downdraft at the top of the stairs. Chase and Inca know where it’s cool. They also do not plan to leave their spots unless I guarantee they are going to the office (where the refrigerated air is really cold).
