OEM vs. Generic

Drain pan fit is critical — an off-size pan can leak around the coil and cause water damage. The OEM Goodman pan guarantees exact dimensions and drain-port alignment. Generic pans are cheaper but often require shimming or sealant to fit and may not match the coil footprint. For a water-management part, OEM is strongly recommended.

Installation Difficulty

Moderate (3/5). Requires pulling the evaporator coil to swap the pan. Recommended for an HVAC technician. Disconnect power and verify proper drain slope after install.
