Air‑Conditioner Temperature Settings Recommended at 26‑27°C for Energy Savings

Consumer experts advise setting residential air‑conditioners to 26 °C–27 °C and using a higher fan speed or automatic mode. Raising the set temperature by one degree can reduce electricity consumption by roughly 6 %, while a low temperature combined with minimal airflow makes the compressor run longer and uses more power. Taiwan Power Company (Taipower) recommends this range and suggests supplementing cooling with fans or circulation fans to improve air flow.

For senior citizens, the Japanese Environment Ministry recommends keeping indoor temperatures at or below 28 °C, maintaining humidity between 40 %–60 %, and using fans or circulators to distribute cool air evenly. Regular filter cleaning, proper shading, and avoiding direct cold drafts are also advised to prevent heat‑related health risks while keeping energy use low.
