They sell a film for windows (almost like a tinting film, but not really dark). The idea is that heat is reflected off of the windows to help improve your summer cooling needs.





Does anyone have this kind of product? I'm in dire need to improve my cooling (AC unit is under-sized and I don't have thousands of $$). I'd love to hear a review from someone who has tried this.





Also, any other simple improvements I could make? I've done the obvious: balance the load on air ducts/returns; replace filter; clean compressor and radiator fins.

|||Window film can help reduce ultraviolet light, which is a source of heat gain in a building. However any window treatments will accomplish the same task, i.e. blinds, curtains etc... I would recommend examining your return duct for leakage, checking the insulation level in your attic and perhaps forward me any technical information about your residence (a/c model#'s inside unit and outside unit as well as manufacturer of both, square footage, location of dwelling, type of construction etc...) and I will examine and return a simple analysis.
