Non-Inverter AC Conventional air conditioners are non-inverter types where the compressor run on fixed speed. Meaning it can only control the indoor temperature by either starting or stopping the compressor.   Inverter AC Inverter technology allows air conditioners to be more powerful whilst being more energy efficient at the same time. The compressor of the inverter air conditioners work at various speeds. As such, electronic control allows the rotation speed of the inverter motor to automatically regulate to reach the required temperature rapidly, and to keep it stable. The benefits of inverter air conditioning units provide a remarkable advantage; low noise, energy savings and optimal temperature without sudden changes.
