The Goodman 20201901 is a genuine OEM condensate drain hose tube built for the Goodman ACVM960604CXBA high-efficiency furnace and related models. It carries condensate from the furnace's collector box and secondary heat exchanger to the drain trap, keeping the drainage path clear and protecting internal components from standing moisture.
As a genuine Goodman OEM hose, the 20201901 matches the factory length, diameter, and routing exactly, ensuring a secure, leak-free connection. Universal generic hoses cost less but frequently need cutting and can slip off the barb fitting under thermal cycling. The OEM part eliminates guesswork and protects your warranty.
Easy (1/5). Push the hose onto the fitting, secure the clamp, and verify the routing — typically a 10–15 minute job with no special tools. Disconnect power and gas before beginning service.
