Ge ns15a42sa5 3.5 Ton 15 SEER2 Single-stage Air Conditioner

Product Description

The GENERAL ELECTRIC ns15a42sa5 is a single-stage residential central air conditioner rated at 3.5 tons and 15 SEER2. It operates on R454B refrigerant, a lower-GWP alternative that aligns with current regional refrigerant transition requirements. The unit is approved for North-only installation, meaning it must be paired with an approved air handler or furnace coil in a North-region compliant configuration. Licensed HVAC technicians handle installation and commissioning. The cabinet ships at 211 pounds and features 45-degree service valves with extended connections that allow routine service access using standard, readily available tools.

This condensing unit is designed for residential split-system cooling applications. The single-stage compressor delivers consistent cooling capacity without variable-speed modulation, making it a straightforward replacement or new-installation option in ducted residential systems. North-only distribution applies to this model, so confirm regional eligibility before ordering. The unit pairs with a compatible indoor coil and air handler to complete the refrigeration circuit.

Compatibility

Approved for North-region installation only. Must be matched with a compatible indoor coil and air handler or furnace that meets the system pairing requirements for this model. Verify matched-system documentation before installation.

Installation Notes

Installation must be performed by a licensed HVAC technician in accordance with local mechanical codes and the manufacturer's installation instructions. Disconnect and lock out all electrical power before making any connections or accessing refrigerant circuits. R454B is an A2L mildly flammable refrigerant — follow all applicable safety protocols and local code requirements for handling and charging. Confirm that the indoor coil and refrigerant line set are rated for use with R454B before commissioning.
