If you have every reason to keep your AC unit (portable, window, etc.) for a few more years, be prepared to stock up on additional ventilation hoses (accordion hose) with plastic connector rings, etc. In the case of Window type AC, do get additional accordion blind parts (or they call it baffle or window frame installation kit)....trouble with these units is that the plastic pieces tend to go bad rather quickly, and becomes almost impossible to acquire down the road... most kits aren't expensive to begin with (avg between 39USD to 69USD, from factory parts).....so if you have a 500bucks unit, your extra installaion/cooling/accessory kit will make your unit lasts longer, serves you better,and up your resale value...
