OEM vs. Generic

This genuine Goodman OEM pan matches the factory footprint, drain port location, and coil seating exactly. Universal pans often require trimming or repositioning the coil and may not align with the existing drain fitting, leading to overflow and water damage. The OEM pan drops in for a clean, leak-free fit.

Installation Difficulty

Moderate (3 of 5). Replacement requires shutting off power, accessing the coil section, removing the evaporator coil to extract the old pan, fitting the new pan, and reconnecting the drain line. A qualified technician should verify proper slope to the drain and test for leaks before returning the unit to service.
