1. A heating, ventilation, and air conditioning (HVAC) system, comprising:
an evaporator unit, comprising:
a housing configured to contain an evaporator coil, the housing comprising an air intake side and an air discharge side;
a first sealing structure disposed along the housing;
a first actuator coupled to the first sealing structure and operable to move the first sealing structure between a first position and a second position;
the evaporator coil configured to receive an airflow and to transfer heat from the received airflow to a flow of refrigerant; and
a fan disposed downstream of the evaporator coil configured to introduce the airflow into the housing;
a compressor configured to receive the flow of refrigerant from the evaporator coil and to discharge the flow of refrigerant at a higher pressure;
a condensing unit comprising a condenser configured to receive the flow of refrigerant from the compressor and to reduce a temperature of the flow of refrigerant; and
a controller operably coupled to the evaporator unit, comprising:
a processor, configured to:
determine if the HVAC system is transitioning from a first mode of operation to a second mode of operation, wherein the first sealing structure is in the first position during the first mode of operation; and
in response to determining that the HVAC system is transitioning from the first mode of operation to the second mode of operation, actuate the first actuator to move the first sealing structure to the second position, wherein the second position is configured to seal the air intake side of the housing;
wherein during the second mode of operation:
the compressor is turned off; and
the fan is turned off.

8. A method of operating a heating, ventilation, and air conditioning (HVAC) system, comprising:
operating the HVAC system in a first mode of operation, wherein operating the HVAC system in the first mode of operation comprises sending a command to actuate an evaporator coil contained in an evaporator unit and a compressor;
determining if the HVAC system is transitioning from a first mode of operation to a second mode of operation, wherein a first sealing structure coupled to the evaporator unit is in a first position during the first mode of operation; and
in response to determining that the HVAC system is transitioning from the first mode of operation to the second mode of operation, actuating a first actuator to move the first sealing structure from the first position to a second position, wherein the second position is configured to seal an air intake side of a housing of the evaporator unit; and
operating the HVAC system in the second mode of operation, wherein the compressor is turned off during the second mode of operation.

14. An evaporator unit, comprising:
a housing configured to contain an evaporator coil, the housing comprising an air intake side and an air discharge side;
a first sealing structure disposed along the housing;
a first actuator coupled to the first sealing structure and operable to move the first sealing structure between a first position and a second position;
the evaporator coil configured to receive an airflow and to transfer heat from the received airflow to a flow of refrigerant;
a fan disposed downstream of the evaporator coil configured to introduce the airflow into the housing; and
a second sealing structure disposed along the air discharge side of the housing operable to selectively seal the air discharge side of the housing.
