We sure do!! We had an old central air conditioner when we moved in here & promptly added a new furnace & new AC!! I also run a couple fans to keep the air moving when it's really hot!
I remember when I was a kid & we had NO AC...lucky i didn't get my head caught in a fan I slept so close to it! lol And wjhen we finally got a window unit in the living room we ALL slept in there!!
Gets pretty hot & HUMID in Iowa!

At work, my office is above the DELI & we have the AC & 3 fans running full time...all that heat from the deli rises, while cool air goes down! MAn it is unbeareable some days...so....I go down to the meat cooler to cool off!! rotfl!
