I feel it made a difference in my home. I decided to go for a safety film vs a straight solar film for a little more protection. It does have a tint to it but I didn't want to go too dark because I still wanted light coming inside the house. I went with this brand (http://www.solargard.com/window-films/residential/safety-films/solar-safety-films). They also make solar films that provide more heat rejection http://www.solargard.com/window-films/residential/solar-control-films Ceramic window films may provide more heat rejection while maintaining light but at a higher cost.
Most of the brands (3m, solargard, huper optic, etc.) will have a find dealer option. From there, you'll get suppliers near your zip. Get a few quotes from different brands and dealers as they will set the price. When I looked, 3M was really high. Panorama and ArmorCoat were close but looks like they are both from the same parent company; Solargard). I tried to get a quote for HuperOptik but don't remember if I ever did. Also, some of the energy films may qualify for a Tax credit.
ok.. Thanks a bunch... I need to do something this summer, can't be at home burning up all summer like last year.
Shades Also got these. Duette® Architella® honeycomb shades They claim to save energy in summer and winter. I was able to claim an energy credit on my taxes too. http://www.hunterdouglas.com/2013EnergySmartStyle/index.jsp
