Description
Overview
This matched Goodman split-system package combines one GLXS4BA3610 R-32 outdoor air conditioner with one GD9T800805CX GD9T80 gas furnace and one CHPTA3630C3 evaporator coil. It is a 3 ton, 36,000 BTU/h nominal cooling system built around a single-stage outdoor section and a forced-air indoor air handler section. The outdoor unit uses R-32 refrigerant and is factory charged for 15 feet of interconnecting tubing to simplify commissioning. The indoor furnace provides two-stage natural gas heat with a 80% AFUE rating and uses a 9-speed ECM blower for ducted air delivery. The indoor coil is a cased horizontal a-coil (evaporator coil) designed for horizontal installation, and it includes a factory-installed TXV for controlled refrigerant metering. Together, these components operate as one integrated ducted cooling-and-gas-heat system using standard 24V controls and 208/230V single-phase outdoor power.
Performance
Cooling performance is driven by a single-stage scroll compressor and a PSC condenser fan motor that support stable airflow through the outdoor coil. The GLXS4B series is rated up to 15.2 SEER2, with realized efficiency determined by the matched coil, blower setup, and installation conditions. Refrigerant connections use 0.38" liquid and 0.88" suction service valves to align with common 3 ton line-set sizing. Indoors, the furnace blower provides the system’s air delivery and can be configured for the required CFM to match coil capacity and duct static pressure. The TXV-equipped coil supports consistent superheat control across operating conditions, improving stability during cycling and varying load. Across the package, the outdoor condenser rejects heat to ambient while the indoor coil absorbs sensible and latent heat from return air for a conventional split-system refrigeration circuit.
Smart Features
Controls are based on standard 24V thermostat signaling so the system can be applied with widely used non-communicating thermostats. The furnace control board supports self-diagnostics and integrates heating safety logic with blower timing for staged heat operation. Blower speed configuration is set at the furnace, allowing installers to select airflow targets for cooling, heating, and continuous circulation modes. If zoning dampers are used in the duct system, the ECM blower provides a range of airflow options that can be matched to zoning design and static pressure limits. The outdoor section uses conventional contactor-based control and includes protection devices that interrupt operation under abnormal pressure conditions. This architecture keeps service access straightforward by separating refrigerant service at the condenser from combustion and airflow service at the furnace and coil.
Comfort & Noise
Acoustic performance is supported by the outdoor unit’s published 67 dBA rating for the 3 ton chassis, helping manage exterior noise in residential and multi-family placements. Two-stage gas heat reduces temperature swing by operating at a lower firing rate when load is moderate, then stepping to high fire when demand increases. The ECM blower enables lower continuous fan speed options for air mixing while maintaining controlled ramping for heating and cooling calls. Air delivery quality is governed by duct design and airflow setup, with the coil selected to align cabinet size and refrigerant connections to the furnace platform. The TXV coil stabilizes evaporator operation as indoor load changes, supporting humidity removal in cooling mode when airflow and charge are properly set. Overall comfort is produced by coordinated capacity at the outdoor condenser, metering at the coil, and airflow control at 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 air distribution system. The horizontal coil orientation supports common install scenarios such as vertical closets and basements for CAPTA coils or attic and crawlspace horizontal runs for CHPTA coils. The furnace is designed for downflow or horizontal left/right installation, supporting layout flexibility when supply and return are constrained by structure. R-32 refrigerant is used for the refrigeration circuit, and installers should follow applicable A2L handling practices and local code requirements. In coastal or high-wind regions, the outdoor cabinet can be properly anchored to meet 2023 Florida Building Code unit integrity requirements when installed with the appropriate anchoring method. This configuration fits mixed-humid and hot-humid climates where staged gas heat and controlled evaporator metering help manage seasonal load changes.
Value & Reliability
Reliability is supported by outdoor components including a factory-installed filter drier, an enclosed contactor, and a high-pressure switch that protect the refrigeration circuit. The outdoor cabinet uses steel louvers and a coil guard to reduce incidental damage while maintaining airflow across the condenser coil. The coil cabinet includes insulated casing and a thermoplastic drain pan with secondary drain connections to support condensate management. The furnace cabinet is a heavy-gauge steel enclosure with low cabinet air leakage targets and serviceable access for blower and controls. Across the system, common service valve sizes and standard electrical requirements support parts availability and routine maintenance workflows. AHRI certification and ETL listing provide standardized performance and safety references for the matched equipment family.
Summary Wrap-Up
As a complete ducted split system, this package pairs a 3 ton R-32 condenser with a 80% AFUE two-stage gas furnace and a TXV-metered indoor coil to cover both cooling and heating seasons. The outdoor unit provides the refrigeration work while the furnace supplies airflow, filtration interface, and staged combustion heat. The selected coil completes the refrigerant circuit indoors and is matched by cabinet size and orientation to support practical installation. For contractors, the system architecture keeps commissioning tasks clear: set airflow, confirm charge, and verify staged heat operation. For wholesale and D2C buyers, the value is a known Goodman equipment family with defined capacities, standard controls, and service-accessible construction. Choose this configuration when you need a conventional ducted AC plus gas furnace system with clear component roles and field-configurable airflow.
