Lookin' good! Those "stock" units never really worked well, especially by today's standards. The condenser relies on a drop in pressure between the fan and the condenser to pull air across it. As such, it won't work well if there are ANY air leaks (gaps, cracks, etc.) between the fan and condenser. Additionally the coil is an old school inefficient design AND parts are difficult if not impossible to find. Because of all that, I installed a Vintage Air Gen II Mini system and couldn't be happier with it. Anyway, just and FYI. I am sure Hawaii is at least as hot and humid as Houston so you will appreciate a strong air conditioner as much as I do.
