Drain pan

A drain pan, also known as a condensate pan, is a component of an HVAC system designed to collect water that forms as condensation when warm, humid air comes into contact with the cold surfaces of the indoor evaporator coil. This condensed water drips into the drain pan and is then directed away from the system through a drain line to prevent water damage and maintain proper operation. It plays a critical role in handling moisture generated during the cooling process.
