Which of the following carriers moisture from the air handler to a discharge area?

1. Air ducts

2. Condensate drain

3. Drain pan

4. Return vent

The correct answer is: Condensate drain

The condensate drain is designed to carry moisture away from the air handler to a discharge area. In HVAC systems, especially in air conditioning, moisture is generated during the cooling process when warm air is cooled and condensation occurs. This moisture collects in the drain pan, and the condensate drain then channels it away from the air handler safely outside or to a designated drainage point. The other choices serve different functions within an HVAC system. Air ducts distribute conditioned air, the drain pan collects any condensation that occurs, and the return vent is responsible for bringing air back into the system for reconditioning. However, it is the condensate drain that specifically handles the removal of moisture from the air handler itself, making it the correct answer.
