Why is a drainage system critical in HVAC applications?

A drainage system is critical in HVAC applications primarily because it is essential for removing condensate water generated during the cooling process. When air passes over the evaporator coils of an air conditioning system, moisture from the air condenses on the coils and turns into water. Without a proper drainage system, this water would accumulate and could lead to water damage, fostering an environment conducive to mold growth and other structural issues.

The efficient removal of condensate ensures that HVAC systems operate effectively without the risk of leaks and water pooling, which can compromise the integrity of the system and the building. While energy efficiency, noise reduction, and humidity control are also important factors in HVAC applications, they are secondary to the immediate need for managing condensate water to prevent potential damage and health hazards.
