Goodman 3 Ton Electric HVAC System with Heat Kit – Up to 15.2 SEER2

The Goodman 3 Ton Electric HVAC System is a complete residential straight-cool configuration designed for properties that use an air handler and electric resistance heat instead of a gas furnace. It combines a Goodman GLXS4BA3610 outdoor air conditioner, an AMST42CU1300 multiposition air handler, and a selectable electric heat kit.

This configuration provides approximately 36,000 BTU per hour of nominal cooling capacity. Correct system sizing must be determined through a professional load calculation that accounts for the property’s location, insulation, windows, construction, occupancy, and ductwork.

Goodman 3 Ton Electric HVAC System Overview

The GLXS4BA3610 is a 3-ton, single-stage split air conditioner from Goodman’s R-32 GLXS4B series. Goodman identifies this series as offering efficiency ratings of up to 15.2 SEER2. The exact certified efficiency depends on the indoor equipment combination and must be confirmed through the applicable AHRI certificate.

The outdoor air conditioner uses R-32 refrigerant and includes an energy-efficient scroll compressor, factory-installed filter drier, service valves with sweat connections, a high-pressure switch, and a fully charged refrigerant circuit designed for up to 15 feet of tubing under the manufacturer’s specified conditions.

What’s Included

The Goodman 3 Ton Electric HVAC System includes the primary heating and cooling equipment listed below.

• Goodman GLXS4BA3610 air conditioner: Three-ton outdoor condenser with approximately 36,000 BTU of nominal cooling capacity, single-stage operation, and R-32 refrigerant.
• Goodman AMST42CU1300 air handler: Multiposition indoor air handler with a direct-drive, multi-speed ECM blower motor, all-aluminum evaporator coil, and internal factory-installed thermal expansion valve.
• Selectable electric heat kit: Choose the Goodman HKTSD08X1 8 kW, HKTSD10X1 10 kW, or HKTSD15XB 15 kW electric heat kit. Each available option includes a circuit breaker.

Installation materials such as the thermostat, refrigerant line set, condenser pad, disconnect, wiring, drain components, duct transitions, and mounting accessories are not included unless specifically listed in the selected configuration.

System Compatibility

Correct compatibility is essential when configuring the Goodman 3 Ton Electric HVAC System.

The GLXS4BA3610 outdoor air conditioner has a nominal capacity of 3 tons, while the AMST42CU1300 air handler has a nominal capacity of 3.5 tons. A larger nominal indoor unit may be paired with a smaller outdoor unit only when the combination, airflow settings, and installation are approved.

The presence of both models in this package does not independently confirm a particular SEER2 rating. The equipment match, required airflow configuration, electric heat kit, refrigerant piping, and applicable AHRI certificate should be verified before purchase and installation.

The heat-kit selection must be based on the property’s heating load, climate, electrical-panel capacity, required branch circuits, and applicable electrical codes. The 15 kW option requires substantially more electrical capacity than the 8 kW or 10 kW options.

Use the AC sizing calculator as an initial reference, but do not substitute it for a professional Manual J load calculation. You can also compare this system with other electric HVAC systems available from Xpress Supply.
