The Goodman 20201902 23-inch Condensate Drain Hose is the genuine OEM pre-cut drain tube for the ACVC90704CXAA 96% AFUE condensing gas furnace. Measuring 23 inches, it provides the exact run length needed to connect the furnace's collector box and trap to the condensate discharge. Brittle, kinked, or biofilm-clogged hoses are a leading cause of furnace water leaks and pressure-switch faults — this factory-length hose restores proper drainage in one step.
The OEM Goodman hose arrives pre-cut to 23 inches with the correct inside diameter, so it drops straight onto the factory barbed fittings — no measuring or guesswork. Generic bulk tubing costs less but must be cut to length and may not match the ID, risking slip-offs or flow restriction. For a precise, leak-free fit, choose the OEM hose.
Easy (1/5). Pull the old hose off its fittings, push the new 23-inch hose onto the same connections, and secure clamps if present. About 5–10 minutes. Power down the furnace and have a towel ready for drips.
