Of course, do make sure to buy an AC unit that is a bit stronger if you have high ceilings, live in a hot climate, and have an above-average sun in those rooms.PACs should really be emptied and cleaned at the end of every summer season, and easily accessible fans and filters make that job a whole lot easier.

I’m never quite sure if the spirit of the advice not to oversize is not to say install a 30,000BTU unit when you needed a 6,000BTU but perhaps there is much less harm if you install a 15,000BTU when you needed a 10,000BTU?
