Description
Overview
This matched Goodman split-system package combines one GLXS4BA3610 R-32 outdoor air conditioner with one GR9T800603BX gas furnace and one CHPTA3630B3 evaporator coil. It is a 3 ton, 36,000 BTU/h nominal cooling system paired with ducted gas heat for a single air distribution path. The outdoor condenser uses R-32 refrigerant and is designed for conventional split-system line-set connections to the matched indoor coil. The furnace provides two-stage combustion heat while the ECM blower establishes airflow across the evaporator 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. In heating mode, the furnace operates in low and high fire stages from 42,000 to 60,000 BTU/h input to better track load and manage temperature rise. Indoors, airflow is configured at the furnace to support the coil’s heat transfer and the duct system’s static pressure constraints. The TXV coil stabilizes refrigerant metering under changing indoor load to support consistent evaporator superheat and latent capacity.
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 system coordinates ignition sequencing, safety proving, and blower timing, and it supports onboard diagnostics for service troubleshooting. Blower speed selection is configured at the furnace to set airflow targets for cooling, heating, and continuous circulation. GR9T furnaces include provisions associated with A2L system monitoring used with R-32 equipment, supporting integration of sensor and alarm logic when applied in the system design. When applied with zoning dampers, airflow setup and duct design determine how well the system maintains coil temperature, airflow balance, and noise control across zones. This split architecture keeps service roles clear by separating refrigerant service at the condenser from combustion, 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. Two-stage furnace operation reduces on/off cycling by using low fire for moderate demand, then stepping to high fire when load increases. 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 furnace supports upflow or horizontal left/right installation, while the 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. For GR9T96 configurations, the furnace uses PVC venting and can be configured as 1-pipe (exhaust only) or 2-pipe (dedicated combustion air) depending on installation design and code requirements. For GR9T80 configurations, venting is Category I non-condensing and combustion air requirements are governed by the installation environment and applicable codes. The furnace NOx classification for this model is < 40 NG/J NOx, which may support compliance requirements in regulated air districts depending on jurisdiction.
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. Coil cabinet insulation and drain pan features support condensate management when installed with proper trapping and drainage. Airflow tuning is supported by the ECM blower and a cabinet width matched to the selected evaporator coil for stable air distribution. 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 a 80% AFUE GR9T800603BX two-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, venting and condensate completion where applicable, and verification of ignition and safety operation. For wholesale and D2C buyers, the value is a defined Goodman equipment set that uses serviceable components and conventional split-system architecture. Select this configuration when you need ducted central cooling with staged gas heat and clear component roles across the refrigeration and combustion sections.
