An AC heater coil is an essential component of an air conditioning system. It is responsible for converting the heat energy from the air outside into the cool air that is circulated throughout the home. The AC heater coil works by absorbing the heat from the outside air and transferring it to the refrigerant inside the air conditioning system. The refrigerant then carries the heat energy to the evaporator coil, where it is released as cool air. The AC heater coil is typically made of copper or aluminum and is located in the outdoor unit of the air conditioning system. It is important to keep the AC heater coil clean and free of debris, as this can reduce its efficiency and cause it to overheat. Regular maintenance and cleaning of the AC heater coil can help ensure that your air conditioning system runs smoothly and efficiently.
