The Goodman 20201802 Condensate Drain Hose Tube is a genuine OEM replacement line for the high-efficiency ACVC950714CXAC condensing gas furnace and compatible Goodman/Amana models. This flexible, corrosion-resistant tube carries acidic condensate between the heat exchanger, drain trap, and pressure switch. Over time the original hose can harden, crack, or clog with scale — causing leaks, blocked drainage, and pressure-switch lockouts. Replacing it restores reliable condensate flow.
This genuine Goodman OEM hose is the correct inside diameter and length for a snug, leak-free connection at the factory barbed fittings. Generic tubing may not seal properly or may degrade quickly when exposed to acidic condensate. OEM tubing is matched to the furnace and built to last.
Easy (DIY-friendly). Slide the old hose off the barbed fittings and press the new one into place, securing any clamps. Shut off power and gas first, then check for leaks on the next heating cycle. Estimated time: 10–20 minutes.
