Close blinds and drapes on sun-struck windows before noon, deploy reflective film where permitted, and position portable shades outside to block radiant heat. Encourage cross-ventilation at night and early morning, then seal the cool air by midday. Planting a shade tree or installing an awning can dramatically reduce indoor heat gain over time. Passive steps cost little, lower stress on your AC, and create naturally calmer rooms. Tell us which window faces gave you the biggest improvement.
Set ceiling fans to spin counterclockwise for a cooling breeze; they make rooms feel up to 4°F cooler, letting you raise the thermostat without sacrificing comfort. Program a smart thermostat to pre-cool before peak pricing, then relax setpoints slightly when rates rise. Each degree of higher cooling temperature can save roughly 3–5 percent. Teach everyone to turn fans off when leaving rooms—they cool people, not spaces. Compare routines with friends and swap schedules that actually stick.
