Daikin Inverter HVAC

What’s an Inverter?

An inverter is energy-saving technology that eliminates wasted operation in air conditioners by efficiently controlling motor speed. Typically, air conditioners maintain a set temperature by cooling and heating when a room falls above or below it. In inverter type air conditioners, the temperature is adjusted by simply changing the motor speed without needing to turn the motor on and off. The result is less power usage and better energy savings.
