Stay away from mini split units! Cheap materials, every brand uses the same cheap compressor inside, every brand is chinesse, it will rust in a couple of years in front on the beach! No parts for repairs, lots of leaks! We recomend american or even mexican units such as central units and split units! Don't use oils or other stuff on fins, reduces efficiency, clogs the air flow, the best u can do is wash the coil once a while and cover the unit when not in use! We offer the units service (recomended once a year) for 70 bucks, cleaning coils, checking terminals and freon pressure, and we have parts if something need to be replaced! Just PM me!
