What is the role of a condensate drain in an HVAC system?

The role of a condensate drain in an HVAC system is to remove excess moisture. In air conditioning systems, during the cooling process, moisture in the air condenses into water. This condensate needs to be effectively managed to prevent water buildup, which can lead to issues such as mold growth, system inefficiency, or damage to the unit and surrounding areas.

The condensate drain directs this collected water away from the HVAC system, ensuring that it operates smoothly and efficiently while maintaining proper humidity levels within the space being conditioned. This is essential for both the comfort of occupants and the longevity of the HVAC equipment.
