The Goodman 20201902 23-inch Condensate Drain Hose Tube is a genuine OEM replacement for the Goodman ACVC90905DXAA condensing gas furnace. Cut to the factory 23-inch length, this drain tube carries condensate from the furnace's collector box and trap assembly to the drain, helping prevent overflow, water damage, and pressure-switch faults from a blocked or split line.
Because this hose is pre-cut to the exact 23-inch run the ACVC90905DXAA requires, it installs with no measuring or guesswork. Generic bulk tubing forces you to trim to length and frequently uses an off-spec inner diameter that leaks at the barbed connections or kinks in tight cabinets. The OEM 20201902 is matched to Goodman's drainage layout for a clean, reliable fit.
Easy (DIY-friendly). Plan on about 10 minutes. Shut off power to the furnace, remove the old hose from the trap and outlet fittings, push the new 23-inch tube fully onto the barbs, and verify there are no kinks along the run. Restore power and confirm condensate flows freely with no drips. When in doubt, have a licensed HVAC professional perform the swap.
