The Goodman 20201802 Condensate Drain Hose Tube is a genuine OEM tubing segment used in the condensate drainage system of the Amana/Goodman AMVC950453BXAB high-efficiency condensing furnace and related AMVC95/GMVC95 models. It routes acidic condensate from the collector box and drain trap to the drain outlet, maintaining a leak-free path and proper water seal.
Over time, condensate hoses can crack, harden, kink, or clog with sediment and biofilm — leading to water leaks inside the cabinet, tripped pressure switches, and no-heat faults. Replacing the hose with the correct factory-spec tube restores reliable drainage and prevents costly water damage.
OEM vs. Generic: The genuine 20201802 matches the exact inner diameter, length, and material rating for the AMVC95 drain layout, ensuring secure connections and a proper seal. Generic tubing may not fit the port diameters or resist condensate acidity, risking leaks. OEM is recommended.
Install difficulty: Easy. Power down the furnace, slide off the old hose, and press the new tube onto the fittings; secure clamps if used. No special tools required. Prime the trap and check for leaks on the first heat cycle.
