5 Power-Saving Myths — Customer Response

5 popular myths from Korean forums/news

Check: **Myth 1**: 'Inverter = infinite ON-OFF OK' → Reality: startup current 5-10x; frequent cycle shortens compressor life. **Myth 2**: 'Keep 24°C is saving' → Reality: 22°C 30min + 26°C 4hr saves more than 24°C 4.5hr. **Myth 3**: 'Fan-only mode = cool' → Reality: fan = compressor OFF = no cooling, humidity unchanged. **Myth 4**: 'Powerful mode always = cooler' → Reality: 1-3 hr max, then auto-normal; sustained use +30% power. **Myth 5**: 'Just clean filter for 1 yr' → Reality: coil/pan/blower uncleaned = mold + 30% efficiency drop.

What to do: **Correct usage**: ① **Out <1 hr** = don't OFF, raise to 26-27°C. ② **Out 2hr+** = OFF, on restart powerful 30 min then normal. ③ **>35°C ambient** = set 26°C (24°C = full load, surge). ④ **Night** = sleep mode + 27°C + fan; never OFF outdoor (restart costs more). ⑤ **Season start** = coil/filter clean + 15 min commissioning. **Cost example**: Korea avg home 1500 kWh/mo, summer +500 kWh ≈ ₩100-150k (progressive tariff: ₩200k+).
