Not true for me. I e had it off for a couple of months now and the windows open. This month it is more on than not. When temps go above 80*, I like to spoils myself and then it on. The pool water today was at 79*’s.Get use to running the AC 11 months out of the year.
This weekend it’s due to be in the high 80’s and I’ll jump in, maybe.
Further south, I can see full time A/C.
