How A Condensate Drain Pan Works When There Are Two?

If you have a horizontally installed furnace or air handler in your attic, you will notice a second condensate drain pan. Your system no longer needs two condensate drain pans to function properly; the second pan serves as a backup for added protection.

Failure of a condensate drain pan poses a significant risk of water damage in a horizontal HVAC system. A condensate pan inability causes water to drip out across the unit instead of funnelling to a general location as it would with a vertical HVAC unit.

Water leaks caused by a failed condensate pan in a horizontal HVAC system cause damage to the wood, drywall, ceilings, and insulation.

The secondary function of a condensate drain pan is to catch the water that may leak out across the unit if the primary condensate pan stops working. It securely catches spilled condensation and directs it out of your home to prevent damage with its own dedicated drain line.
