80,000 BTU Heating Capacity
With an input of 80,000 BTUs and an output of 64,000 BTUs, the GRVT800805CN provides reliable and efficient heating for small to medium-sized homes. Its performance is well-suited for regions with average winter conditions.
80% AFUE Efficiency
Operating at 80% AFUE, this furnace converts 80% of consumed fuel into home heating, while venting 20% as exhaust. Like all standard 80% AFUE models, it requires metal flue venting. For homeowners seeking higher efficiency, Goodman also offers models above 90% AFUE that utilize PVC venting.
Two-Stage Heating with Variable-Speed Blower
The two-stage gas valve allows the furnace to operate at lower capacity during mild conditions and full output during colder weather. Paired with the variable-speed ECM blower motor, the GRVT800805CN maintains consistent airflow, reduces temperature swings, and ensures optimal comfort throughout the home.
Durability and Reliability
Engineered for long-term performance, this furnace features a tubular aluminized steel heat exchanger and a heavy-duty steel cabinet designed to minimize air leakage and reduce noise. These components make the GRVT800805CN a reliable, quiet, and efficient heating solution for years of winter use.
Warranty Protection
The GRVT800805CN comes with Goodman’s 10-year parts warranty and lifetime heat exchanger warranty. To qualify, installation must meet local building codes and the unit must be registered online after installation.
Installation Options
This furnace is factory-set for natural gas but can be converted to propane with an optional LP conversion kit (sold separately). Its design supports both upflow and horizontal installation, making it adaptable for basements, attics, or utility spaces.
With its combination of two-stage heating, variable-speed airflow, and Goodman reliability, the GRVT800805CN is an efficient, durable, and flexible heating solution for small to medium-sized homes.
