About this system
The Goodman GR9S960603BU is a 60,000 BTU, 96% AFUE upflow/horizontal gas furnace built specifically to meet California and Colorado Ultra Low NOx emissions requirements. That NOx compliance is not optional in those states, so if you are buying this unit for a California or Colorado installation, the regulatory box is already checked. The 96% AFUE rating means 96 cents of every fuel dollar becomes heat, placing it firmly in the high-efficiency tier and well above the federal minimum of 80% AFUE. The multi-speed blower motor adjusts airflow across a few fixed speeds rather than continuously, which is a middle-ground between the basic single-speed and the more expensive fully variable ECM units.
At 60,000 BTU this furnace is sized for roughly 1,200 to 2,000 square feet depending on climate zone, insulation, and ceiling height. The upflow/horizontal configuration works with the majority of residential duct layouts, installed in a basement, closet, or attic with the air handler discharging upward or horizontally. The model also lists R-32 on its spec sheet, which is relevant to any matched cooling equipment rather than the furnace itself. If you are replacing only the furnace in an existing system, confirm the refrigerant compatibility of your current coil before purchasing. This is a good candidate for a homeowner who needs code-compliant Ultra Low NOx equipment at a price point below the major premium brands.
The GR9S960603BU delivers genuine 96% AFUE efficiency and mandatory Ultra Low NOx compliance at a price that undercuts comparable Carrier, Trane, and Lennox furnaces by a meaningful margin. The trade-off is a brand track record that leans on solid installation and routine maintenance to reach its potential lifespan, and a history of component failures that start appearing around year 7. For a budget-conscious buyer in a regulated California or Colorado market who uses a reputable installer, it is a defensible choice.
Overall score is the average of the five ratings above.
What we like
- 96% AFUE genuinely reduces gas bills compared to 80% units in cold climates
- Ultra Low NOx certification satisfies California and Colorado requirements out of the box
- Priced 15 to 25 percent below comparable Carrier, Trane, and Lennox furnaces
- 20-year heat exchanger warranty (when registered) is competitive with premium brands
- Upflow/horizontal flexibility fits a wide range of existing duct configurations
Trade-offs
- Brand reliability ratings are below premium competitors, with repair costs climbing after roughly year 7 according to ConsumerAffairs feedback
- Multi-speed blower is less efficient and less quiet than a fully variable ECM motor found on higher-tier models
- Dual-run capacitor failures and evaporator coil leaks are documented recurring issues across the Goodman line
- Long-term performance depends heavily on installer quality, which is an additional variable the buyer cannot fully control
What homeowners and pros say about Goodman
On ConsumerAffairs, Goodman as a brand scores around 2.5 out of 5, a figure shaped in part by the platform’s complaint-heavy audience, but the recurring pattern is real: owners report repair costs rising after roughly year 7, with dual-run capacitor failures and evaporator coil leaks appearing repeatedly in the comments. Google dealer reviews paint a more balanced picture at around 3.8 out of 5, where affordability comes up most often as the reason owners chose the brand and were satisfied with the decision. For the GR9S960603BU specifically, the Ultra Low NOx feature earns consistent approval from California and Colorado buyers who need regulatory compliance without paying a premium-brand price premium.
HVAC technicians tend to view Goodman with measured respect rather than enthusiasm. The most common professional observation is that installation quality determines the outcome more than the equipment itself, and that a well-installed Goodman in a clean duct system will outperform a carelessly installed premium unit. The documented weak points on the broader Goodman furnace and cooling line are capacitors, which are a cheap and fast fix when they do fail, and compressors that tend to average 10 to 14 years rather than the 15 to 20 years more commonly seen in Trane or Carrier units. For a 60,000 BTU high-efficiency furnace in a regulated market, the GR9S960603BU represents a straightforward cost-versus-longevity trade-off that informed buyers can evaluate honestly.

Questions about this system
Does this furnace actually meet California Air Resources Board (CARB) and Colorado Ultra Low NOx rules, or do I need an add-on kit?
The GR9S960603BU is built with an Ultra Low NOx burner that meets CARB and Colorado standards as shipped. No separate kit or field modification is required, which is the main reason this model exists as a distinct SKU from Goodman's standard 96% furnaces.
What is the real difference between the multi-speed blower and a variable-speed ECM motor?
A multi-speed motor steps between a handful of fixed airflow rates and shuts fully off between cycles, drawing more electricity per run and producing more noticeable airflow changes. A variable-speed ECM ramps up and down continuously, runs quietly at low speeds for longer periods, and can cut blower electricity use by 50 to 75 percent. For a 60,000 BTU furnace the efficiency gap matters most in heating-heavy climates where the blower runs frequently.
What is covered under the Goodman warranty and what do I have to do to activate it?
Goodman offers a 20-year heat exchanger limited warranty and a 10-year parts limited warranty, but both require online registration within 60 days of installation to take effect. Without registration, the parts coverage drops to five years. Keep your installation invoice because the registration process requires the install date and contractor information.
How does this unit handle a two-stage or modulating thermostat if I upgrade later?
The GR9S960603BU is a single-stage furnace, meaning it fires at full capacity or not at all. A two-stage or modulating thermostat will not unlock a lower firing rate from this unit. If staged or modulating heat output is a priority, you would need a different furnace model from the outset.
I keep seeing complaints about Goodman furnace repairs around year 7 to 10. Which parts should I budget to replace and what do they cost?
Dual-run capacitors are the most frequently reported failure across the Goodman product line and typically cost 300 to 600 dollars to diagnose and replace. Inducer motors, ignitors, and control boards are the next most common service items on gas furnaces generally, and parts for Goodman are widely stocked by distributors, which tends to keep repair bills lower than for some imported brands. Setting aside a small annual maintenance budget after year 5 is a reasonable precaution.
