Weatherking WA13NY48AJ1NA Condensing Unit 4 Ton 13.4 SEER2

Product Description

The WEATHERKING WA13NY48AJ1NA is a 4-ton residential split-system condensing unit rated at 48,000 BTU/h cooling capacity with a 13.4 SEER2 efficiency rating. It operates on R454B refrigerant, a lower-GWP alternative that meets current regulatory requirements for new equipment. This unit is the outdoor section of a split cooling or heat pump system and requires a matched indoor coil and air handler to complete the installation. Licensed HVAC technicians perform the installation, handling refrigerant recovery, line set connection, and electrical hookup in compliance with EPA Section 608 requirements.

This condensing unit is suited for residential and light-commercial cooling applications where a 4-ton system matches the building load calculation. It is designed for use in split-system configurations with a compatible matched indoor coil. The 13.4 SEER2 rating meets current federal minimum efficiency standards applicable to new equipment installations. Installers should verify that the indoor coil and line set are rated for R454B refrigerant before proceeding.

Key Features

• 48,000 BTU/h nominal cooling capacity (4 tons)

• Outdoor condensing unit designed for split-system cooling installations

Compatibility

Designed as an OEM-style outdoor condensing unit for residential split-system cooling applications. Requires a matched indoor evaporator coil and air handler rated for R454B refrigerant. Verify system component compatibility before installation.

Installation Notes

Installation must be performed by an EPA 608-certified HVAC technician. Disconnect and lock out all electrical power before servicing or connecting refrigerant lines. R454B is a mildly flammable (A2L) refrigerant — follow applicable safety standards and local codes regarding handling, storage, and leak detection. Ensure the outdoor unit is mounted on a level pad with adequate clearance on all sides per manufacturer and local code requirements.
