Goodman 80% AFUE 80K BTU Gas Furnace Variable Speed Upflow/Horizontal 21"W GRVT800804CN

The Goodman GRVT800804CN Gas Furnace is part of Goodman’s premium 80% AFUE furnace series, offering superior heating performance, durability, and efficiency. With a two-stage burner and a variable speed blower motor, this natural gas furnace is engineered to deliver consistent comfort, quieter operation, and long-lasting reliability for homeowners seeking dependable heating.

Quick Facts

  • 80,000 BTU 80% AFUE two-stage variable speed natural gas furnace
  • Ideal for heating small to medium-sized homes in average climates
  • Requires metal flue venting
  • Supports upflow and horizontal installation orientations
  • Convertible to propane with an LP conversion kit (sold separately)
  • Engineered for electrical efficiency, safety, and reduced noise

80,000 BTU Heating Capacity

With an 80,000 BTU input and a heating output of 64,000 BTUs, the Goodman GRVT800804CN is designed to provide powerful and efficient heating for small to medium-sized homes. Its two-stage design allows the furnace to adjust heating levels as needed, maximizing both comfort and efficiency.

80% Efficiency Rating

Operating at 80% AFUE, this Goodman furnace converts 80% of fuel into usable heat while venting 20% through the flue. Like all 80% efficient furnaces, the GRVT800804CN requires metal flue venting for proper installation and safe operation. Higher-efficiency models (90%+) use PVC venting.

Compliance Notice

Please note: The GRVT800804CN does not meet California Low NOx or Ultra-Low NOx emission standards. This furnace cannot be installed in regions that require stricter compliance. Homeowners in California should verify regional air quality requirements before purchase.

Two-Stage Variable Speed Performance

This Goodman furnace uses a two-stage gas valve paired with a variable speed blower motor to deliver precise airflow and steady indoor comfort. The design helps maintain even temperatures, lowers energy usage, and reduces operating noise compared to single-stage furnaces.

Durability and Reliability

Built with a tubular aluminized steel heat exchanger, the GRVT800804CN ensures efficient heat transfer and long-lasting performance. Its heavy-duty cabinet reduces air leakage and sound levels while protecting internal components, making it a durable and reliable heating solution for years of comfort.

Installation & Compatibility

Factory-configured for natural gas, this Goodman furnace can be converted to propane with an LP conversion kit (sold separately). The unit supports both upflow and horizontal configurations, making it flexible for different home layouts. Professional installation is recommended for safety and efficiency.

Why Choose the Goodman GRVT800804CN?

Happy with the product and shipping.

Impressed by the quality

I’ve installed Goodman heat pumps before at a similar price point. This was better quality, and a great deal from the HVAC store. I’m always a little nervous about picking the lowest cost provider but the came through quick and no damage.

I’m in the middle of install so if you don’t see an update, things went well. As I said, first impressions as I opened it up to adjust airflow direction was very impressed!

A good store to shop for HVAC supply

The store did some things I didn't believe the manager was very helpful in fixing my problem

very reliable company and great prices

Bought a few units from this company and they were very friendly and easy to work with. Either matched prices or beat the price and had fast shipping also.

Excellent company to purchase from

I wasn’t to sure about if this company could deliver it quickly but it arrived within a week. No issues. I needed this one for parts as my first one that I installed a year ago had the ecm go out on the blower fan. Parts are hard to come by for this Chinese brand. I think the ecm went out due to condensation in the main supply plenum dripping onto fan motor. I do like this ac unit but hope the fan lasts longer than a year. I covered the fan ecm with flex seal tape.

Goodman 5 Ton System

Excellent value, customer sales support (a human called to confirm online order... greatly appreciated!), fast shipping. Very happy customer.

A + Company

Sale representative Lopez was very experienced and professional. I would recommend this company to any one and I am looking forward to work with Lopez again.
