Aircon works well in most places but uses more electricity. also for it to work well doors and windows need to be closed.
an aircooler also works well but not as good as a aircon, it is a lot cheaper to get a aircooler and uses less electricity. with this best results are found inland, in costal areas it is not as effective. another advantage is you can keep windows and doors open.
the aircooler basically puts more moisture into the air, it takes the hot air, uses the water to cool down and passis it out the other side, no irritation to eyes etc. an aircon however does not do this and tends to dry out the air giving the dry itchy eyes etc.
