Ductless Split Air Conditioner. What is a wall mounted?

Strong, quiet and efficient DC motors are used both indoors and outdoors. High performance fan blades, condensers and evaporators combined with variable speed inverter-driven compressors make for unmatched performance. Variable speed compressors automatically adjust to fluctuating room capacity requirements.

This category of equipment is ideal for smaller spaces where spot cooling or heating is required.  Systems 9R2 and 12R2 are 115 volt heat pumps, making residential applications including sunrooms and additions much easier.

Lg Mini Split Heat Pump. Inverter Technology

Through  advanced technology, Inverter air conditioners are more economical to operate and quieter to run than conventional units. They can handle greater extremes in temperature, are smoother and more stable in operation, and reach the desired temperature more quickly than conventional air conditioners.

The Inverter component allows the outdoor unit to vary its speed and output to match the required capacity of the indoor unit. Thus, the Inverter model can achieve 30% more operating efficiency than conventional models and therefore, is much less expensive to run.     

Wall mounted systems include an extra quiet fan speed ("Quiet Mode") to make sure that you are not disturbed.

Mini Split Air Conditioner. Smart System:  Auto Mode and Humidity Control.

When the system is initially turned on, the fan speed is HIGH to reach the set temperature as quickly as possible.  The fan speed will automatically adjust downward as the room begins to reach the set temperature.
 
This system features Dry Mode, which helps to control humidity levels, even when cooling may not be needed.
