Split units are what are primarily used here in Belize. Added benefit of being much harder to steal than portable or window units.

I have a portable unit and it's kinda a pain. You've still gotta find somewhere to vent it and find a way to get rid of the water. It was free for me though, and works great other than that, so I really have no complaints.


Here in Belize, I usually find out who can competently work on stuff by asking other expats who've been here a while. Word gets around. Plus, you may make some new friends in the process.
