The Goodman GM9S92 is a high-efficiency, budget-friendly gas furnace designed for homeowners seeking dependable heating performance without breaking the bank. With an AFUE rating of 92%, it provides solid energy efficiency compared to older furnaces, helping reduce heating costs while maintaining comfort.
Although it doesn’t carry the ENERGY STAR® certification, the GM9S92 offers consistent performance, reliability, and quiet operation — making it a smart option for homes in moderate climates.
This review covers everything you need to know about the GM9S92, including its performance, features, warranty coverage, installation flexibility, and overall value.
The Goodman GM9S92 features a single-stage gas burner paired with a multi-speed blower motor, offering consistent and efficient heating performance.
While a single-stage furnace operates at full capacity whenever it’s running, the multi-speed blower helps balance airflow, creating more even temperatures throughout your home and improving comfort levels.
With a 92% AFUE rating, this model converts 92% of the fuel it uses directly into heat for your home—meaning only 8% is wasted through exhaust. This makes it a significant upgrade from older, less efficient models.
However, since it lacks ENERGY STAR certification, homeowners seeking maximum energy savings may want to explore Goodman’s higher-efficiency models such as the GM9C96 or GMVM97.
92% AFUE efficiency for improved energy savings
Single-stage burner for reliable and simple operation
Multi-speed blower motor for consistent heat and better airflow control
Aluminized steel heat exchanger for long-lasting durability and corrosion resistance
Self-diagnostic control board for quick troubleshooting and maintenance
Compact, space-saving design ideal for tight installations
Quiet operation with a sealed, insulated cabinet to minimize noise
The GM9S92 is designed for flexible installation, making it suitable for a variety of home setups. Its compact cabinet and multi-position design allow it to be installed in basements, closets, crawl spaces, or utility rooms without hassle.
This model is best suited for small to mid-sized homes or regions with mild to moderate winters. In very cold climates, a two-stage or modulating furnace may be a better choice to maintain consistent comfort and efficiency throughout the day.
Goodman backs the GM9S92 with comprehensive warranty protection, giving homeowners added peace of mind:
10-Year Parts Limited Warranty (with registration)
25-Year Heat Exchanger Limited Warranty (extends to Lifetime if registered within 60 days)

The Goodman GM9S92 is a cost-effective, energy-efficient furnace that delivers dependable heating for smaller homes or moderate climates. Its multi-speed blower and durable aluminized steel heat exchanger contribute to efficient, quiet, and long-lasting operation.
While it lacks some of the advanced features of higher-end models—such as two-stage heating or ENERGY STAR certification—it remains a strong choice for homeowners seeking reliability and value at an affordable price.
With its good warranty coverage, low operating costs, and proven Goodman durability, the GM9S92 provides a great balance between comfort, performance, and affordability.
