The Goodman 20201901 is a factory OEM condensate drain hose tube engineered for the GMV950704CXAB variable-speed condensing furnace. It carries corrosive condensate from the collector box to the drain trap, and replacing a brittle or leaking original protects the heat exchanger area from water damage and rust.
Our OEM hose matches Goodman's factory length and pre-formed bends for a drip-free fit. The Generic option is a same-diameter universal drain tube at a lower price point — a practical choice when exact factory contouring is not essential to your routing.
Easy. Remove the clamp, pull the old hose, install the new one, and re-clamp. Around 10 minutes with basic hand tools. Confirm continuous downward slope so condensate drains fully.
