Do any of you guys prep for losing air conditioning?

I’ve been thinking about buying a couple of window AC units in case of a power outage. Have any of you bought any backup air conditioning units in case of a power outage? I have sources to power them so that’s not an issue.

It can get very hot where I live during hurricane season and it’s possible to lose power during Sunday storms. It’s just something to be a little more comfortable if we lost power.
