About this system
The Goodman GR9S800604BU is a 60,000 BTU, 80% AFUE single-stage gas furnace built specifically for the California market, where Ultra-Low NOx (ULN) emission standards apply. It uses a multi-speed ECM blower motor, which draws less electricity than a standard PSC motor and delivers more consistent airflow and quieter operation than a single-speed unit. The upflow and horizontal configuration options make it a practical fit for attics, closets, and utility rooms common in California tract homes. R-32 refrigerant designation on the label reflects the California-compliant system pairing context rather than a refrigerant contained in the furnace itself.
An 80% AFUE rating means 80 cents of every dollar spent on gas converts to heat, with 20 cents lost through exhaust. That is a respectable baseline for a non-condensing furnace, though it sits below the 90%+ tier that becomes standard in colder climates. For mild California winters, the efficiency gap between an 80% and a 96% unit is less financially significant than it would be in Chicago or Minneapolis, so this system makes real economic sense in the state where it is intended to be sold. The 60,000 BTU output suits homes roughly in the 1,200 to 2,200 square foot range depending on insulation, ceiling height, and local design temperatures.
The GR9S800604BU is a straightforward, code-compliant furnace for California homeowners who need a dependable ULN-rated unit without paying a premium brand price. The ECM motor and 80% AFUE are solid for the mild-winter market it targets, but long-term ownership costs will depend heavily on install quality and whether you budget for capacitor replacements around year 7 or 8. It is not the last furnace you will ever buy, but it is a reasonable one for the price.
Overall score is the average of the five ratings above.
What we like
- Priced 15 to 25 percent below comparable Carrier, Trane, and Lennox ULN models
- ECM blower motor lowers operating electricity costs compared to single-speed PSC motors
- Ultra-Low NOx certification meets California SCAQMD and BAAQMD requirements out of the box
- Upflow and horizontal orientation flexibility covers most California installation scenarios
- Single-stage design is straightforward to diagnose and service, keeping repair labor costs down
Trade-offs
- 80% AFUE is the minimum efficiency tier; homeowners who heat frequently will see higher gas bills versus 96% condensing alternatives
- Dual-run capacitors are the most commonly reported early failure point, typically around year 7 and up, adding $300 to $600 in repair costs
- Compressor and heat exchanger longevity averages shorter than premium brands, with compressors typically reaching 10 to 14 years versus 15 to 20 for Trane or Lennox
- Single-stage gas valve delivers full output or nothing, so temperature swings between cycles are more noticeable than with two-stage or variable systems
What homeowners and pros say about Goodman
On ConsumerAffairs, Goodman as a brand scores around 2.5 out of 5, though that channel skews toward frustrated owners rather than satisfied ones. The recurring pattern in those reviews is not catastrophic failure at installation but a steady climb in repair bills after roughly year 7, with dual-run capacitor failures being the single most common complaint. Evaporator coil leaks also surface with enough frequency to be worth knowing about before purchase. Google dealer reviews tell a noticeably different story, averaging around 3.8 out of 5 across hundreds of reviews per location, where affordability is consistently the top reason owners say they chose Goodman and would again.
HVAC technicians who work on Goodman equipment regularly make a point that is worth taking seriously: the brand’s real-world performance is more tied to who installs it than to the equipment itself. A properly sized, correctly charged, and carefully commissioned GR9S800604BU in a California home will likely give ten or more years of routine service with one or two modest repair calls. The documented weak points on Goodman furnaces specifically are heat exchanger longevity relative to premium brands and the capacitor failures that tend to show up mid-ownership. For a California homeowner who heats only a few months a year, the math on paying a premium brand price often does not work out, which is the honest case for this furnace.

Questions about this system
Is the GR9S800604BU actually certified for use in all California air quality districts?
Yes, the GR9S800604BU is designed to meet California Ultra-Low NOx standards, which require NOx emissions at or below 14 nanograms per joule in districts like SCAQMD and BAAQMD. Always confirm your specific air district's current rules with your installer before purchase, as some districts have updated requirements periodically.
What does the ECM blower motor actually change day to day compared to a standard motor?
An ECM (electronically commutated motor) runs at multiple speeds rather than full-blast or off, which means quieter startup, more even air distribution, and meaningfully lower electrical consumption during fan-only and cooling assist cycles. In practice, homeowners report less of the sudden rush of air that is common with single-speed PSC motors.
Why does this 60,000 BTU furnace list R-32 in the model specs if furnaces do not use refrigerant?
The R-32 designation reflects California's refrigerant pairing requirements for matched HVAC systems sold or permitted in the state. The furnace itself contains no refrigerant; the notation indicates the system is intended to be paired with R-32 compatible cooling equipment under California's evolving refrigerant regulations.
What should I budget for repairs over the first ten years of ownership?
Based on documented owner experience, the most common repair is a dual-run capacitor failure, typically appearing after year 7 and running $300 to $600 for parts and labor. Setting aside $500 to $800 for one service call in the second half of the warranty period is a reasonable expectation for this brand and product tier.
Can this furnace be installed horizontally in an attic, or does it require a specific bracket kit?
The GR9S800604BU supports both upflow and horizontal configurations as listed, which covers the attic and closet installs common in California homes. Horizontal installations do require proper support, a secondary drain pan if near living space, and correct venting pitch; your installer should confirm the accessory requirements specific to your attic layout before the job starts.
