Which HVAC system component removes heat from the inside of a building during the cooling process?

The component responsible for removing heat from the inside of a building during the cooling process is the evaporator unit. The evaporator plays a crucial role in the refrigeration cycle, where it absorbs heat from the indoor air as refrigerant evaporates within it. This heat absorption cools the air that is blown into the living spaces by the blower fan.

While the condenser unit is important in the overall cooling process, its primary function occurs outside the building. The condenser dissipates the heat extracted from the indoor air and releases it outside, effectively completing the refrigeration cycle.

The blower fan facilitates air movement through the HVAC system but does not directly remove heat. It moves the cooled air generated by the evaporator into the indoor environment.

The heat pump can function in both heating and cooling modes, but during the cooling process, it operates similarly to an air conditioner by utilizing the evaporator to cool indoor air.

Thus, the evaporator unit is the correct answer because it is specifically tasked with heat absorption from inside the building during the cooling phase.
