1. Block Solar Heat with Window Coverings

Direct sunlight through windows can drastically raise indoor temperatures—especially in rooms facing the sun. By installing reflective window films, using blackout curtains, or closing blinds during peak sun hours (11 a.m. to 4 p.m.), you can reduce solar heat gain by up to 77%. This simple change helps rooms stay cooler and reduces how hard your AC has to work.

2. Program or Smart-Schedule Your Thermostat

Every degree counts when it comes to savings. Set your programmable or smart thermostat to 78°F when you’re home and 85°F when you’re away. This can reduce cooling costs by 3% per degree, according to the U.S. Department of Energy. Smart thermostats also learn your habits and optimize energy use automatically—ensuring comfort without wasting power.

3. Seal Duct Leaks and Improve Insulation

Up to 30% of cooled air can escape through leaky ductwork, while uninsulated attics allow outdoor heat to seep in. Sealing air ducts, applying weatherstripping to doors and windows, and upgrading attic insulation (ideally to R-38 or higher) keeps your conditioned air indoors—improving comfort and lowering your utility bills.

4. Use Fans and Night Ventilation

Ceiling and box fans create a wind-chill effect that makes the room feel cooler without lowering the thermostat. On cool nights, open windows on opposite sides of your home to promote cross-ventilation, flushing out hot air. Just remember to close them again in the morning to trap cooler air inside.

5. Create Shade with Landscaping

Well-placed trees, bushes, or trellises with climbing vines can block direct sunlight from hitting your windows and walls. Even lighter-colored ground cover like gravel reflects less heat than concrete or asphalt, lowering the radiant temperature around your home.

6. Keep Your AC Equipment Maintained

Change air filters every 30 days during peak usage, gently rinse off your outdoor unit’s coils with a hose (avoiding pressure washers), and have a professional HVAC technician inspect your system once a year. A clean, well-maintained system cools more efficiently and lasts longer.
