The Goodman 20201802 Condensate Drain Hose Tube is a genuine OEM replacement designed for the AMH950703BXAA high-efficiency gas furnace and compatible Goodman/Amana models. This flexible tube routes acidic condensate between the drain trap, collector box, and drain line, and its correct length and inside diameter are critical to maintaining proper flow and pressure-switch signaling.
The genuine OEM 20201802 is pre-cut to the correct length with the exact bore diameter your furnace requires, ensuring proper drainage and reliable pressure-switch operation. Generic hose stock may be the wrong diameter or degrade faster against acidic condensate, leading to leaks and clogs. OEM guarantees a precise, worry-free fit.
Difficulty: Easy. This is a simple slip-on replacement most homeowners can do in a few minutes — remove the old hose and press the new tube onto the fittings. Shut off power before servicing and confirm all connections are snug and free of kinks. When in doubt, consult a licensed HVAC technician.
