What is the primary purpose of the evaporator coil in an HVAC system?

The primary purpose of the evaporator coil in an HVAC system is to absorb heat from the indoor air. When the refrigerant flows through the evaporator coil, it changes from a liquid to a gas as it absorbs heat. This process cools the air in contact with the coil, which is then blown into the living space by the air handler or blower fan.

This function is essential for maintaining a comfortable indoor temperature, as it effectively removes heat from the air, leading to a cooling effect. The evaporator coil works in conjunction with the other components of the HVAC system, including the compressor and condenser, to achieve efficient heat exchange and temperature control.
