Product Description
The GOODMAN alxs4ba4210 is a single-stage, cooling-only outdoor condensing unit built for residential and light commercial split air conditioning systems. Rated at 42,000 BTU/h nominal cooling capacity and 14.3 SEER2 efficiency, it uses R-32 refrigerant and operates on a 208/240-volt, single-phase, 60 Hz power supply. The scroll compressor runs at single speed and discharges airflow from the top of the cabinet. This unit is produced in the United States and carries DOE regional compliance for all U.S. climate zones. Licensed HVAC technicians perform the installation and startup on this type of equipment.
This outdoor unit is intended for residential, multi-family, and light commercial split-system cooling applications. It pairs with a compatible indoor coil to form a complete cooling system. The non-communicating configuration means it works with standard, non-proprietary thermostat and air handler controls. The unit is factory pre-charged with R-32 refrigerant for a standard line set length of 15 feet, with a maximum line set run of 200 feet and a maximum vertical rise of 79 feet. Operating ambient temperature range runs from 55 degrees F to 125 degrees F under standard cooling conditions.

Installation Notes
Installation must be performed by a licensed HVAC technician holding an EPA Section 608 certification, as R-32 is an A2L mildly flammable refrigerant subject to specific handling requirements under applicable safety codes. Disconnect and lock out all electrical power before making any wiring connections or refrigerant line connections. Confirm minimum circuit ampacity and maximum overcurrent protection ratings match the electrical service panel capacity before energizing the unit. Follow local mechanical and electrical codes, including NEC requirements for disconnect placement and equipment clearances.
