Frequently Asked Questions

What is digital inverter technology in AC?

Digital inverter technology uses a variable-speed compressor controlled by digital electronics to continuously adjust cooling output based on room temperature, rather than switching the compressor fully on and off. This results in more precise temperature control, lower energy consumption, quieter operation, and faster cooling recovery compared to fixed-speed non-inverter air conditioners.
