Experts recommend setting the thermostat a few degrees higher when away to balance energy efficiency, comfort, and humidity.
Turning off the AC for several hours saves money and energy but may cause mold in humid climates and wear on the system.
Adjusting the thermostat by 7-10°F (4-6°C) for eight hours can save up to 10% annually on heating and cooling.
In dry climates like Arizona, raising the thermostat more is feasible, while humid climates like Florida risk mold if AC is off too long.
Increasing the thermostat by 1°F (0.6°C) saves about 3% in cooling costs.
Homes with heavy materials (e.g., concrete, brick) retain cool air longer, while older, draftier homes heat up faster.
Window units are less efficient; sealing drafts with foam insulation can help retain indoor temperatures.
Smart thermostats can save around 10% by adjusting temperatures based on occupancy.
U.S. residential and commercial AC consumes 4-7% of total energy, excluding data centers.
Simple cooling strategies include blocking sunlight, opening windows at night, and using reflective blinds or tinted films.
