Description
Overview
This matched Goodman split-system package combines one GLXS4BA3610 R-32 outdoor air conditioner with one GR9S800604BX GR9S80 gas furnace and one CHPTA3630B3 evaporator coil. It is a 3 ton, 36,000 BTU/h nominal cooling system paired with an 80% AFUE forced-air gas heat section for ducted distribution. The outdoor condenser uses R-32 refrigerant and is designed for conventional split-system line-set connections to the matched indoor coil. The indoor furnace is a single-stage platform with a 9-speed ECM blower that provides system airflow across the coil and through the duct system. The coil is a cased horizontal a-coil (evaporator coil) built for horizontal installation and includes a factory TXV for controlled refrigerant metering. Together, these components operate as one integrated ducted cooling-and-gas-heat system using standard 24V thermostat control with non-communicating equipment logic.
Performance
Cooling performance is driven by a single-stage scroll and condenser fan that cycle to match thermostat demand. The GLXS4B series is rated up to 15.2 SEER2, with realized efficiency dependent on the matched coil, blower configuration, and installation conditions. Refrigerant connections use 0.375" liquid and 0.875" suction service valves consistent with typical 3 ton line-set sizing. Indoors, the furnace blower can be configured for target airflow to support the coil’s heat transfer and duct static pressure limitations. The TXV coil stabilizes refrigerant metering under changing indoor load to support consistent evaporator superheat and latent capacity. In heating mode, the furnace delivers approximately 48,000 BTU/h output at 60,000 BTU/h input, with induced draft venting and integrated combustion safeties.
Smart Features
Controls follow standard 24V heat/cool call logic, supporting widely used non-communicating thermostats and third-party smart thermostats that provide conventional outputs. The furnace control board coordinates ignition sequence, safety proving, and blower timing, and it supports onboard diagnostics for service troubleshooting. The 9-speed ECM blower enables selectable airflow profiles for cooling, heating, and continuous fan operation without changing the outdoor control architecture. When applied with zoning dampers, blower speed selection and duct design determine how well the system maintains airflow balance and coil temperature across zones. The outdoor section uses contactor-based operation and integrated refrigeration safety devices to interrupt operation under abnormal conditions. This split architecture keeps service roles clear by separating refrigerant service at the condenser from ignition, airflow, and condensate service at the indoor section.
Comfort & Noise
Outdoor acoustic performance is supported by a published 67 dBA rating for the 3 ton chassis to help manage exterior noise at the placement location. Because the furnace is single stage, heating temperature stability is primarily determined by thermostat cycle rate, duct losses, and airflow configuration rather than staged firing. The ECM blower supports smoother airflow transitions and can be configured for lower continuous circulation speeds for improved mixing and filtration through the return path. Cooling comfort is governed by coil sizing and airflow balance, with cabinet width matching used to control face velocity across the indoor heat exchanger. Humidity performance depends on achieving the intended evaporator temperature through correct airflow and refrigerant charge, with the TXV helping maintain stable metering. Overall comfort is produced by coordinated heat rejection at the outdoor coil, heat absorption at the indoor coil, and ducted air delivery through the furnace blower.
Use Case Fit
This package is suited for ducted residential applications and can support light commercial or multi-family use where one outdoor condenser serves one duct system. The GR9S80 furnace supports upflow or horizontal left/right installation to accommodate utility closets and horizontal runs when vertical space is constrained. The CHPTA3630B3 coil supports horizontal mounting to match common vertical or horizontal duct layouts. R-32 refrigerant is used for the refrigeration circuit, and installation should follow applicable A2L handling practices and local code requirements. The furnace NOx classification for this model is < 40 NG/J NOx, which may support compliance requirements in regulated air districts depending on jurisdiction. This configuration fits mixed-humid and hot-humid climates where airflow setup and coil selection are used to manage seasonal sensible and latent loads.
Value & Reliability
Reliability is supported by outdoor components including a factory-installed filter drier, accessible service valves, and refrigeration safety devices used for protection and diagnostics. The outdoor cabinet and louvered construction are designed to maintain condenser airflow while protecting the coil face from incidental impact. The furnace integrates safety controls for flame sensing, pressure proving, and limit protection to manage combustion operation over repeated cycles. Airflow tuning is supported by the 9-speed ECM blower and a cabinet width matched to the selected evaporator coil for stable air distribution. The coil cabinet provides a dedicated condensate drain interface and insulated casing to help manage cabinet sweating and condensate formation. Across the package, standard electrical requirements and conventional 24V controls support straightforward replacement and service workflows.
Summary Wrap-Up
As a complete ducted split system, this package pairs a 3 ton R-32 condenser with an 80% AFUE GR9S800604BX GR9S80 single-stage gas furnace and a TXV-metered CHPTA3630B3 evaporator coil to provide cooling and gas heat in one matched architecture. The outdoor condenser performs the refrigeration work, while the indoor coil provides the evaporator heat transfer surface and the furnace supplies airflow and combustion heat. Cabinet widths are selected so the furnace and coil align for practical installation and stable air distribution across the coil face. For contractors, commissioning focuses on blower airflow setup, refrigerant charge verification, and confirmation of ignition and safety operation. For wholesale and D2C buyers, the value is a defined Goodman equipment set that uses standard controls, serviceable components, and conventional split-system architecture. Select this configuration when you need ducted central cooling with an 80% AFUE gas furnace and clear component roles across the refrigeration and combustion sections.
