The Goodman 20201901 is a genuine OEM condensate drain hose/tube designed for the ACVC950714CXAD high-efficiency gas furnace. This longer drain run channels acidic condensate from the collector box and trap to the furnace's drain outlet on 90%+ AFUE condensing systems. When a drain hose cracks, kinks, or clogs, condensate backs up into the pressure switch and inducer, triggering lockouts and water leaks. Installing the correct OEM hose restores reliable drainage and protects the heat exchanger and inducer assembly.
This OEM hose ships at the exact factory length and inside diameter for your furnace's routing, so it seats fully on each barbed port without adapters. Generic tubing requires cutting to length and matching the ID/durometer — get it wrong and you risk kinks, blow-offs under condensate pressure, or leaks at the fittings.
Easy (1 of 5). Plan on 15–20 minutes. Shut down the furnace, remove the old hose from its fittings, route the new hose along the same path, and press it fully onto each port. Verify there are no kinks before restoring power. No special tools or refrigerant work needed.
