In order to help homeowners shop for furnaces and air conditioners, we developed our own proprietary algorithms which weigh a range of criteria and factors to provide an easy-to-compare grade (e.g. B-, A+, etc).
Warranty Grade: It can be difficult to know which brands and models offer the best warranty coverage, particularly because a lot of the key details are hidden in dense warranty documents filled with hard to understand legalese. Thankfully for you, weโve carefully studied them and created this grading system to account for things like the length AND quality of their guarantee, coverage restrictions and more!
Overall Grade: This grade weighs key factors like efficiency, ENERGY STAR certification, comfort, noise level (for A/Cs), our warranty grade, and more.

This review highlights the features, benefits, and overall performance of the Goodman GR9S80 to help you decide if itโs the right fit for your home.
Goodman GR9S80 Overview
AFUE Rating: 80%
Burner Type: Single-stage
Blower Type: Single-speed
Heating Capacity: 40,000 - 67,000 BTUs
ENERGY STAR Certified: Yes
Key Features
- Heavy-duty aluminized-steel tubular heat exchanger for durability and efficiency
- Single-stage gas valve for steady heating performance
- Durable hot-surface igniter for long-lasting ignition reliability
- Quiet, single-speed induced draft blower to minimize operating noise
- Self-diagnostic control board for quick troubleshooting and maintenance
Performance and Efficiency
The 80% AFUE rating means that 80% of the fuel is converted into usable heat, while the remaining 20% is lost through exhaust. This makes the Goodman GR9S80 an economical option for homes in areas with moderate winter conditions.
As a single-stage furnace, it runs at full capacity whenever it is heating, which may result in higher energy usage compared to two-stage models. However, it is still a cost-effective and dependable heating solution for many homeowners.
The single-speed blower motor ensures consistent airflow, and the hot-surface igniter enhances reliability by eliminating the need for a pilot light.
