I'm like you, Rob...I probably wouldn't turn on the AC at all in the summer if it weren't for Brandon -- he is an absolute toaster! The way I see it, I wait all winter for 80 degree weather so I can wear shorts and tank tops and go swimming, so AC is kind of defeating the purpose.
But my kitties need it too -- they spend a lot of time laying on their backs spread eagle in the summer. I know they get hot. Ours makes no noise and comes in through ceiling vents, so it's not really an issue.
