AC Efficiency Tips
- Choose the right size unit: An oversized AC cools quickly but cycles on and off frequently, wasting energy. An undersized unit runs constantly without adequately cooling.
- Clean or replace filters monthly: Dirty filters restrict airflow and force the unit to work harder, increasing energy consumption by up to 15%.
- Use a programmable thermostat: Set the temperature higher when you are away and lower it before you return to avoid cooling an empty space.
- Seal windows and doors: Prevent cool air from escaping by sealing gaps and cracks around windows, doors, and ductwork.
- Use fans to circulate air: Ceiling or box fans help distribute cool air more evenly, allowing you to set the thermostat a few degrees higher.
- Block direct sunlight: Close blinds or curtains during peak sun hours to reduce heat gain and lighten the load on your AC.
