Goodman 40,000 BTU 96% AFUE Gas Furnace

Upgrade your home’s heating efficiency with the Goodman GD9S960403BN, a high-performance 40,000 BTU natural gas furnace delivering **96% AFUE (Annual Fuel Utilization Efficiency)** for maximum energy savings. Designed for **multi-speed operation**, this single-stage downflow model features an **ECM motor** that optimizes airflow, reduces noise, and enhances comfort while lowering energy costs. The **aluminized steel heat exchanger** ensures durability and reliable heat distribution, making it an ideal choice for homes in non-California regions (this model does not meet California emissions standards).

With a **17.5″ cabinet width**, this furnace is built for horizontal/downflow installation only—**not upflow** (for upflow models, look for GR9 series). It replaces older Goodman models (GD9S960403BN, GC9S960403BN, etc.) and is **R-32 refrigerant-ready** for nationwide compatibility. Note: California buyers require a different model due to stricter emissions regulations. Accessories like line sets and LP conversion kits are sold separately.
