The Goodman 20201901 Drain Hose Tube is a genuine OEM condensate hose for the ACVC951155DXAA high-efficiency gas furnace and compatible Goodman/Amana models. This larger-run tube connects the furnace's condensate components to the drain trap and outlet, channeling acidic moisture safely away from the cabinet and electronics. The factory part is pre-bent to clear internal components and made from corrosion-resistant material rated for continuous condensate exposure.
The OEM hose matches the exact length, diameter, and bend radius of your furnace's drain layout, seating securely on the factory barbs. Generic tubing often needs to be cut and forced into position, where wrong-diameter ends or sharp kinks cause leaks and condensate backups that lock the furnace out on the pressure switch.
Easy (DIY-friendly). Typically a 5–15 minute job: detach the worn hose, route the new pre-formed tube along the same path, and secure the clamps. Shut off power and gas before servicing, then run a full heat cycle to verify there are no leaks at the connections.
