What is the purpose of drain pans in HVAC installations?

The purpose of drain pans in HVAC installations is to collect condensate. When systems such as air conditioners or dehumidifiers operate, they remove moisture from the air, which can result in the formation of condensation. This condensate needs to be directed away from the unit to prevent water damage or the growth of mold and mildew. The drain pan effectively captures this moisture, allowing it to flow towards a designated drainage system or be expelled outside. Properly functioning drain pans are crucial for maintaining a safe and efficient HVAC system, as they help manage water that could otherwise lead to serious issues if left unaddressed.
