80,000 BTU Performance

The Goodman GR9S800805CU furnace offers an 80,000 BTU input, producing 64,000 BTU’s of heat per hour (80,000 x 80% AFUE). This makes it suitable for heating medium-sized homes in moderate climates. The furnace is an excellent choice for those looking to balance performance and efficiency without overspending on energy costs.


80% Efficiency Rating

With an 80% Annual Fuel Utilization Efficiency (AFUE) rating, the GR9S800805CU ensures that 80% of the gas burned is converted into usable heat, and only 20% is lost through the venting system. This level of efficiency is typical for standard furnaces and is ideal for those seeking a reliable heating system without needing to upgrade to higher efficiency models.


Single Stage Furnace

The Goodman GR9S800805CU operates as a single-stage furnace, meaning it always operates at 100% capacity when the thermostat calls for heat. This straightforward design provides reliable heating with a simple on/off operation, making it an excellent choice for users who prefer efficiency without the complexity of multi-stage systems.


Multi-Speed ECM Blower Motor

Unlike traditional PSC motors, the 9-speed ECM blower motor on the GR9S800805CU uses less power and provides more efficient air circulation. This helps improve overall energy efficiency and reduces your electrical consumption, lowering your utility bills while keeping your home warm.


Durable Hot Surface Igniter

The GR9S800805CU furnace is equipped with a durable hot surface igniter, which is more reliable and energy-efficient than older ignition systems. This component significantly reduces maintenance costs and provides faster, more efficient ignition to get your furnace up and running quickly.


Self-Diagnostic Control Board

Thanks to the self-diagnostic control board, this furnace allows for easy troubleshooting and maintenance. The control board includes built-in sensors that can detect basic issues, alerting you to the need for maintenance or warranty work. This improves the overall safety and reliability of the furnace and helps avoid potential system failures.


Heavy Gauge Steel Cabinet

The furnace’s heavy gauge steel cabinet ensures that the internal components are well-protected, allowing for a longer lifespan. Additionally, this design helps make the unit more airtight, improving its energy efficiency by reducing heat loss and minimizing noise during operation.


Ease of Installation

The Goodman GR9S800805CU is designed for easy installation, offering flexibility with its ability to be installed in either upflow or horizontal configurations. This makes it suitable for a variety of home layouts, whether you need it in your attic, basement, or utility closet. The furnace also features color-coded low-voltage terminals for a simpler, quicker installation process, reducing labor costs and installation time.


Warranty and Reliability

For added peace of mind, the Goodman GR9S800805CU furnace comes with a 10-year parts warranty and a lifetime heat exchanger warranty when registered online. This extensive coverage ensures that your furnace will continue to provide reliable heating for years to come, backed by Goodman’s reputation for durability and performance.
