Climate control works well enough in the Texas summer heat, but takes a toll on range. To partially offset that, I had Spectra PhotoSync tint installed (SPH 70 on the windshield and SPH 30 on all other windows). It's made a substantial difference in when, how often, and at what level I have to run the AC. (The film is said to aid in heat retention in winter, but I haven't had a chance to test that, yet.)
