Description
Overview
This matched Goodman split-system package combines one GLXS4BA1810 outdoor air conditioner with one GD9T800603AX gas furnace and one CAPTA2422A3 evaporator coil. It is a nominal 1.5 ton ducted cooling system paired with ducted gas heat for a single air distribution path. The outdoor condenser provides refrigerant compression and heat rejection, while the indoor coil provides the evaporator heat transfer surface within the duct system. The furnace supplies combustion heat and establishes airflow across the coil using its ECM blower for cooling, heating, and circulation modes. The coil is a cased upflow/downflow evaporator coil built for upflow or downflow (vertical) 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 capacity control is handled at the outdoor section, while indoor comfort depends on correct airflow setup, coil selection, and refrigerant charge. The TXV coil stabilizes metering under changing indoor load to support consistent evaporator superheat and latent performance. The furnace operates as a two-stage platform to manage heat delivery relative to load, reducing overshoot when staged operation is available. In heating mode, furnace input ranges from 42,000 to 60,000 BTU/h depending on firing stage and demand. Indoor airflow is configured at the furnace to support duct static pressure constraints while maintaining coil temperature targets. Overall system performance is achieved by coordinating refrigerant-side heat transfer at the coil with air-side delivery through the duct network.
Smart Features
Controls follow conventional 24V heat and cool call logic, supporting non-communicating thermostats and third-party smart thermostats with standard outputs. The furnace control system manages ignition sequencing, safety proving, and blower timing, with diagnostics used for troubleshooting. ECM blower speed selection enables airflow tuning for cooling and heating profiles without changing the outdoor control architecture. When applied with zoning dampers, airflow setup and duct design determine how well the system maintains coil temperature stability and zone balance. Service roles stay clear by separating refrigeration service at the outdoor unit from ignition and airflow service at the furnace section. This architecture supports typical replacement and service workflows for ducted split systems.
Comfort & Noise
Comfort is governed by coil face velocity and duct design, with cabinet widths selected so the furnace and coil align for stable air distribution. Staged furnace operation, when present, uses low fire for moderate demand and transitions to high fire when load increases. The ECM blower supports smoother airflow transitions and can be configured for continuous circulation for improved mixing and filtration through the return path. Cooling humidity performance depends on achieving intended evaporator temperature, which is sensitive to airflow setup and refrigerant charge, with the TXV helping stabilize metering. Noise behavior is strongly influenced by duct static pressure and airflow selection at the furnace rather than the refrigerant circuit alone. Overall comfort is produced by coordinated heat rejection outdoors, 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 upflow or downflow (vertical) mounting to match common vertical or horizontal duct layouts. Combustion venting requirements follow the furnace platform, including PVC direct vent for condensing models and Category I venting for non-condensing models. Zoning can be applied with dampers where duct design supports stable airflow and coil temperature control in each zone. The furnace NOx classification for this model is < 40 NG/J NOx, which may support compliance requirements depending on jurisdiction. This configuration fits applications where a defined equipment set is used to deliver central cooling and ducted gas heat through one air path.
Value & Reliability
Reliability is supported by conventional split-system architecture with serviceable indoor and outdoor sections and accessible refrigerant and airflow service points. 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 features support condensate management when installed with proper trapping and drainage. Airflow tuning is supported by the ECM blower, helping match coil performance to duct static and filtration requirements. Standard electrical interfaces and 24V control wiring simplify replacement and service across common installations. Across the package, the value is predictable commissioning steps focused on airflow setup, charge verification, and combustion safety validation.
Summary Wrap-Up
As a complete ducted split system, this package pairs one GLXS4BA1810 outdoor condenser with a 80% AFUE GD9T800603AX gas furnace and a TXV-metered CAPTA2422A3 evaporator coil. The outdoor condenser performs the refrigeration work, while the indoor coil provides evaporator heat transfer and the furnace supplies airflow and combustion heat. Component roles remain separated for serviceability, with refrigeration diagnostics at the condenser and ignition and airflow diagnostics at the furnace. Commissioning centers on blower airflow configuration, refrigerant charge verification, venting completion where applicable, and confirmation of ignition safety operation. For wholesale and D2C buyers, the value is a defined Goodman equipment set with conventional controls and serviceable subassemblies. Select this configuration when you need ducted central cooling paired with gas heat and clear component roles across the refrigeration and combustion sections.
