Overview
- Keep air-conditioning set between 24–26°C because lower setpoints do not cool faster and each degree below recommended levels can raise energy use substantially.
- Use inverter or ECO/AUTO/SLEEP modes and timers to match cooling to need, and run units before rooms become very hot so systems work more efficiently.
- Clean or replace filters and check airflow, louvers and door and window seals, since dirty filters and open gaps make units work harder and cut performance.
- Combine appliance habits with home measures—lower blinds during peak sun, ventilate at night, defrost fridges and unplug standby devices—to reduce overall household consumption.
- Utilities offer tools and incentives to help: Endesa’s InfoEnergía reports average users save about 10% and loyalty programmes reward measured reductions as demand for AC and cooling systems rises with hotter summers.
