Description
Overview
This matched Goodman split-system package combines one GLXS4BA3610A R-32 outdoor air conditioner with one GD9S800804BN GD9S80 gas furnace and one CAPTA3626B3 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 whole-home distribution. The outdoor unit uses R-32 refrigerant and is factory charged for 15 feet of interconnecting tubing to support standard installation practices. The indoor furnace is a single-stage platform with a nine-speed ecm blower that provides system airflow across the coil and through the duct system. The coil is a cased upflow/downflow evaporator coil designed for upflow or downflow (vertical) mounting to match common upflow/downflow furnace applications. Together, these components operate as one integrated ducted cooling-and-gas-heat system using standard 24V thermostat control.
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 indoor coil, airflow setup, and installation conditions. Refrigerant connections use 0.38" liquid and 0.88" suction service valves consistent with typical 3 ton line-set sizing. Indoors, the furnace blower is configured to deliver target CFM for cooling and heating while managing duct static pressure within system limits. The evaporator coil completes the refrigerant circuit indoors and provides heat transfer for both sensible and latent capacity when charge and airflow are set correctly. In heating mode, the furnace delivers approximately 64,000 BTU/h output at rated input, with combustion airflow managed by an induced-draft venting system.
Smart Features
Controls follow conventional 24V staging logic, supporting widely used non-communicating thermostats and control panels. The furnace control board provides self-diagnostics and coordinates ignition, safeties, and blower timing for consistent starts and shutdowns. The nine-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 options can be matched to zoning design and required airflow to avoid excessive coil temperature drop or noise. The outdoor section uses standard contactor-based control and integrates refrigeration safety devices to interrupt operation under abnormal pressure conditions. This split architecture keeps service access clear by separating refrigerant service at the condenser from combustion and airflow service at the furnace and coil.
Comfort & Noise
Outdoor sound performance is supported by a published 67 dBA rating for the 3 ton chassis to help manage exterior noise near patios and lot lines. Because the furnace is single stage, temperature stability in heating relies on thermostat cycle rate, duct losses, and blower setup rather than staged firing. The ECM blower supports smoother airflow transitions and can be configured for lower continuous circulation speeds for improved mixing. Cooling comfort is governed by coil selection and airflow balance, with the coil cabinet size aligned to typical furnace widths for stable face velocity. Humidity control is achieved through correct airflow and refrigerant charge so the evaporator operates at the intended temperature and latent capacity. Overall comfort is produced by coordinated capacity at the outdoor condenser, heat transfer at the indoor coil, and controlled duct airflow from the furnace.
Use Case Fit
This package is suited for ducted residential applications and can also support light commercial or multi-family use where a single outdoor condenser serves one duct system. The GD9S80 furnace is built for downflow or horizontal left/right installation, supporting utility closets and horizontal runs when vertical space is constrained. The CAPTA coil supports upflow or downflow (vertical) mounting for common upflow/downflow furnace layouts and closet installations. 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 (N code), which may support compliance requirements in regulated air districts depending on jurisdiction. This configuration fits mixed-humid and hot-humid climates where correct airflow and coil selection are used to manage seasonal latent and sensible loads.
Value & Reliability
Reliability is supported by outdoor components including a factory-installed filter drier, sweat service valves, an enclosed contactor, and a high-pressure switch. The outdoor cabinet uses steel louvers and a coil guard to reduce incidental damage while maintaining condenser airflow. The furnace cabinet is heavy-gauge steel and integrates safety controls for flame sensing, pressure proving, and limit protection. Multi-position service access and left/right utility connections support practical field routing for gas and electrical service. 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 common cabinet widths support routine maintenance and parts availability.
Summary Wrap-Up
As a complete ducted split system, this package pairs a 3 ton R-32 condenser with an 80% AFUE GD9S80 single-stage gas furnace and a CAPTA cased evaporator coil to cover both cooling and heating seasons. The outdoor condenser provides the refrigeration work while the furnace supplies airflow, filtration interface, and combustion heat. The indoor coil completes the refrigerant circuit and is sized to match cabinet width for controlled air distribution across the heat transfer surface. For contractors, commissioning is centered on airflow setup, refrigerant charge verification, and confirmation of ignition and safety operation. For D2C and wholesale buyers, this configuration provides a defined Goodman equipment set with standard controls and conventional serviceability. Select this package when you need a conventional ducted AC plus gas furnace system with clear component roles and field-configurable airflow.
