Ductless air conditioning systems operate using a heat transfer method that includes refrigerant working in a closed-loop between the heat pump outside and the HVAC air handlers inside your place.
Also, in every room, the HVAC air handler pulls in warm air, and it comprises both an indoor air-handling unit and outdoor compressor units.
Moreover, in a ductless heating system, heat gets transferred through a process of condensation and evaporation, as a refrigerant substance passes through the machine via a compressor pump.
