Ge ns22a48ma5 4-ton 22 SEER2 Inverter Air Conditioner

Product Description

The GENERAL ELECTRIC ns22a48ma5 is a 4-ton inverter-driven central air conditioner rated at 22 SEER2 and charged with R454B refrigerant. The inverter compressor modulates capacity to match load conditions, reducing short-cycling and improving efficiency over single-stage units. Designed for residential split-system installations, this condensing unit pairs with a compatible indoor coil and air handler. Service access uses ordinary, readily available screws, and the 45-degree service valves with extended connections are positioned for straightforward refrigerant-circuit service. Licensed HVAC technicians handle installation and commissioning.

This condensing unit is sized for residential applications requiring 4-ton cooling capacity. It is intended for split-system configurations where the outdoor condensing unit connects to a separately installed indoor evaporator coil and air handler. The R454B refrigerant charge means technicians must be equipped and certified for A2L refrigerants before performing any refrigerant-circuit work. The gray cabinet finish is suited for standard residential pad or rooftop mounting where local codes allow.

Key Features

• Inverter compressor modulates speed for variable-capacity operation and improved efficiency

• R454B refrigerant — lower global warming potential A2L refrigerant
• 45-degree service valves with longer connections for easier field access
• Serviceable with ordinary, readily available screws — no specialty fastener tools required
• Limited 10-year entire-appliance parts warranty with product registration

Compatibility

Designed for residential split-system air conditioning installations requiring a 4-ton R454B inverter condensing unit. Specific compatible indoor coil and air handler pairings should be confirmed against the manufacturer published system matching guide before installation.

Installation Notes

Installation must be performed by an EPA Section 608-certified HVAC technician with A2L refrigerant handling authorization, as R454B is a mildly flammable refrigerant classification. Disconnect and lock out all electrical power to the system before making any electrical or refrigerant connections. Follow local mechanical and electrical codes, including applicable sections of the NEC, for disconnect sizing, line-set routing, and equipment clearances. Refer to the manufacturer installation instructions for specific wiring, line-set sizing, and startup procedure requirements.
