Run AC at 30 degrees in winters for almost zero electricity bill
- •Setting a standard cooling AC to 30 degrees Celsius in mild cold will not blow hot air because standard ACs are designed only for cooling.
- •When room temperature is below 30 degrees, the thermostat turns off the compressor and only circulates the existing air.
- •Electricity consumption is very low at 30 degrees because the compressor remains off and only the indoor fan runs, consuming just 30 to 50 watts.
- •To get warm air during winter like a heater, a special Hot and Cold AC using reverse cycle technology is required.
- •If running the AC in mild cold for ventilation or reducing dampness, it is wiser to use Fan Mode to protect the compressor and save power.
Key Questions Answered
No, a standard AC is designed only for cooling and will not warm up your room. When set to 30 degrees during mild cold, the room temperature is usually lower, causing the thermostat to turn off the compressor so that only the indoor fan runs.
Electricity consumption is very low because the main compressor remains completely turned off at 30 degrees. Only the indoor fan operates, consuming roughly 30 to 50 watts of electricity, similar to a regular table fan.
To get warm air like a heater during winter, a standard cooling-only unit will not work. Instead, you need a special 'Hot and Cold' AC that operates using reverse cycle technology to provide comfortable warmth.
