The answer to 'how does evaporator coil work' is that the evaporator coil is a critical component of an HVAC system that helps cool and dehumidify the air in your home. The evaporator coil is located inside the indoor unit of your HVAC system and contains refrigerant that absorbs heat from the air passing over it. As the refrigerant in the coil evaporates, it draws heat from the surrounding air, cooling it down. This cooled air is then circulated throughout your home by the blower fan.
The evaporator coil works in conjunction with the other components of the HVAC system, such as the compressor and condenser coil, to create a continuous cycle of refrigerant flow that allows the system to efficiently cool and dehumidify the air. The size and efficiency of the evaporator coil are crucial factors in determining the overall performance and energy usage of your HVAC system.
