The Goodman 20201901 is a genuine OEM condensate drain hose tube designed for the AMVC950704CXAD modulating condensing gas furnace. This tube carries acidic condensate from the collector box and secondary heat exchanger to the drain trap. Because it is a longer, pre-formed routing segment, it is a common replacement when the original hardens, cracks, or collapses over years of thermal cycling — a failure that triggers water leaks and pressure-switch lockouts.
The OEM Goodman 20201901 matches the factory length and molded bends exactly, ensuring a strain-free, leak-tight install without kinking. Our Generic equivalent delivers the same acid-resistant durability at a lower cost for standard repairs. Both are backed by our fit guarantee for this model.
Rating: Easy (2/5). Roughly a 10–15 minute repair — trace the existing routing, release the clamps at each fitting, remove the old tube, and install the new one along the same path. Confirm secure, leak-free connections and proper drainage. Shut off power before servicing.
