A method of operating a heating, ventilation, and air conditioning ("HVAC") system (100), the HVAC system (100) comprising a first portion (145a) of evaporator circuits (145) and a second portion (145b) of evaporator circuits (145), the first portion (145a) of evaporator circuits (145) being adapted to receive refrigerant from a first refrigerant path and the second portion (145b) of evaporator circuits (145) being adapted to receive the refrigerant from a second refrigerant path. The method comprises determining, by a controller (190) of the HVAC system (100), a first value associated with the HVAC system (100), wherein: the first value is calculated based on a speed of an air blower of the HVAC system (100) and a total capacity of the HVAC system (100) and the air blower is operable to push a minimum volume of air in to the enclosed space. The method further comprises upon determining that the first value of the HVAC system (100) exceeds a cooling threshold or that the first value of the HVAC system (100) exceeds a dehumidification threshold, instructing, by the controller (190), a valve (180) of the HVAC system (100) to close such that refrigerant cannot flow to the first portion (145a) of evaporator circuits (145) of the HVAC system (100).
