The Goodman 20201901 is an OEM condensate drain hose tube engineered for the GCH950704CXAC high-efficiency gas furnace and compatible Goodman/Amana models. It routes condensate away from the heat exchanger and secondary drain assembly, preventing water pooling, corrosion, and nuisance shutdowns caused by clogged or cracked tubing.
This is a genuine Goodman OEM tube molded to the exact bend radius and connection diameter of your furnace. Generic aftermarket hose may fit loosely, kink, or fail to seal at the barbed fittings — leading to leaks. OEM guarantees a leak-free seal and correct drainage slope.
Easy (1/5). A DIY-friendly swap — pull the old hose from its fittings, seat the new tube, and secure the clamp. No tools beyond a screwdriver required. Always shut off power and gas before servicing.
