I do at night, just for the bedroom. Need it to sleep well. I Keep it around 75-78 in the house in the daytime, on hot days, and just dress for it, no problem then.

I've lived in a house with no AC and even slept outside on a hammock on the hottest days (luckily that was a house built in the 19-teens so it could cope with AC-less heat better than modern houses, but still, on nights when your nighttime lows were still in the high 70s and the air wasn't moving, outdoors was cooler than indoors) and I didn't acclimate, I just only got like 3 hours of sleep a night when it was hot, every single time it was hot.

Need the cold for sleep. I'd have to move farther north for my own sanity if not for AC (and I'm already far enough north I only need AC to achieve low-60s nighttime temps for 60-70 nights per year). I could lay off it a little if work didn't still expect me to function when it's hot, but they do.
