FAQ

Q.
What is the difference between an inverter air conditioner and a non-inverter air conditioner?
A.
The difference between inverter air conditioners and non-inverter air conditioners is the control of the compressor operating speed.Non-inverter air conditioners have compressors working at the same speed regardless of indoor temperature, turning off when the desired temperature is reached and turning on again when the temperature rises. Inverter air conditioners operate by adjusting the compressor speed faster at higher temperatures and slower at lower temperatures.
