But you install air conditioning in April you said. I don't care about the temp in the winter. If folks prefer it hotter, so be it. Doesn't matter at all, do what feels right. But by installing A/C in April, it gives a different signal that one doesn't like it warmer. That's something done by someone who hates being uncomfortably hot. You want to be 68F and dry 365/7/24 a year. A narrow range of air temperature to live in, I prefer more of a range throughout the seasons. Everyone is different.
