OEM Goodman 23x20 Vertical Drain Pan for AEPF426016AA — B1756020L

The Goodman B1756020L Vertical Drain Pan is a genuine OEM condensate pan sized 23 x 20 inches OD for AEPF426016AA air handlers installed in the upflow / vertical orientation. It captures condensate from the evaporator coil and channels it to the drain line, protecting the cabinet, ductwork, and surrounding structure from water damage. A cracked or rusted pan that overflows is one of the most common air-handler service calls — this exact-fit replacement seals the problem.

OEM vs. Generic

This genuine Goodman OEM pan is molded to the precise footprint, drain-port location, and coil clearances of the AEPF cabinet. Generic pans rarely line up with the factory drain fitting and can trap standing water, encouraging algae and overflow. The OEM pan drops in and drains correctly.

Install Difficulty

Moderate — requires pulling the evaporator coil to swap the pan and re-sealing the primary and secondary drain connections; budget 45–60 minutes. Flush the drain line while you're in there.
