Q&A

Q: What heating capacity and efficiency does this Goodman furnace deliver?
A: The Goodman GR9T961004CN provides 100,000 BTU input (≈96,000 BTU output) with a 96% AFUE efficiency, converting nearly all fuel into usable heat to reduce energy waste and lower heating costs.

Q: What type of gas valve and stages does it feature?
A: It includes a two‑stage gas valve, allowing the furnace to run at reduced capacity during milder weather and at full capacity when needed for maximum comfort.

Q: What blower motor does the furnace use?
A: The unit is equipped with a multi‑speed ECM blower motor (9‑speed), delivering efficient, quieter airflow and improved heating performance.

Q: What installation orientations are supported?
A: Designed for upflow or horizontal (left/right) installation, giving flexibility for basements, attics, or closets.

Q: What electrical and venting requirements are there?
A: Operates on standard 115 V single‑phase power and — as a high‑efficiency condensing furnace — requires plastic/PVC flue venting.

Q: What durability and performance features are included?
A: Features include stainless steel secondary heat exchanger, silicon nitride igniter, heavy‑gauge insulated cabinet, self‑diagnostic control board, and low‑speed fan options for quiet circulation.

Q: What fuel types is it compatible with?
A: Factory configured for natural gas and can be converted to propane (LP) with an optional conversion kit.

Maintenance Tips

• Replace or clean air filters every 1–3 months to maintain airflow and prevent dust buildup on the heat exchanger and blower.

• Inspect the heat exchanger annually for cracks or corrosion to ensure safe and efficient operation.

• Clean burners, pilot assembly, and ignition system for reliable two-stage combustion.

• Check the blower motor and fan assembly for dust, debris, and lubrication needs.

• Inspect venting and flue pipe for obstructions or leaks to ensure safe exhaust of combustion gases.

• Test gas valves, two-stage operation, and thermostat for accurate temperature control.

• Verify 115V electrical connections and inspect wiring for wear or corrosion.

• Keep surrounding area clear to maintain airflow and reduce fire hazards.

• Schedule annual professional HVAC service for full inspection, cleaning, and safety testing.
