The Goodman 20201802 is a factory condensate drain hose/tube built for the ACVC950714CXAD high-efficiency gas furnace. It carries acidic condensate between the collector box, trap, and drain outlet on 90%+ AFUE condensing furnaces. Over time, drain hoses harden, crack, or clog with biofilm and scale, leading to water leaks, pressure-switch trips, and nuisance furnace shutdowns. Replacing a worn hose with the correct OEM length and diameter restores proper drainage and keeps your furnace running through the heating season.
This genuine Goodman hose is pre-cut to the correct length and inside diameter for a slip-fit, leak-free connection at the trap and collector ports. Generic bulk tubing must be measured and cut, and the wrong durometer or ID can kink, pop off under condensate pressure, or fail to seal — all common DIY pitfalls.
Very Easy (1 of 5). A 10–15 minute swap. Power down the furnace, slide the old hose off the barbed fittings, push the new hose fully onto each port, and confirm a snug fit. No tools or refrigerant handling required.
