Weatherking WP14AY24AJ2NA Heat Pump 2 Ton 14.3 SEER2

Product Description

The WEATHERKING WP14AY24AJ2NA is a 2-ton residential heat pump rated at 14.3 SEER2, designed for split-system heating and cooling applications. It operates on R454B refrigerant, a lower-GWP alternative to R-410A that complies with current EPA refrigerant transition requirements. The unit delivers 24,000 BTU/h of cooling capacity and features two-stage operation, which allows the compressor to run at a reduced stage during moderate load conditions and shift to full capacity during peak demand. This approach improves efficiency, reduces short cycling, and provides more consistent indoor comfort. Licensed HVAC technicians handle installation and commissioning of this equipment.

This heat pump is suited for residential split-system installations where an ARI-matched indoor coil and air handler or furnace are already in place or being installed simultaneously. Two-stage operation pairs well with variable-speed or multi-speed air handlers to maximize system efficiency and humidity control. The R454B refrigerant charge requires technicians certified to handle mildly flammable A2L refrigerants per current EPA Section 608 requirements. Typical applications include new construction and changeout projects in single-family and light-commercial residential settings.

Key Features

• 24,000 BTU/h cooling capacity at 2 nominal tons
• 14.3 SEER2 efficiency rating meets current minimum efficiency standards
• Two-stage compressor operation reduces short cycling and improves dehumidification
• R454B refrigerant charge complies with EPA A2L low-GWP refrigerant transition guidelines
• Split-system outdoor unit designed to pair with a matched indoor coil and air handler

Compatibility

Designed as an OEM-style residential split-system heat pump outdoor unit intended for use with a manufacturer-matched indoor coil and air handler or furnace to form a rated, tested system combination.

Installation Notes

Installation must be performed by an EPA Section 608-certified HVAC technician with A2L refrigerant handling authorization, as R454B is classified mildly flammable. Disconnect and lock out all electrical power to the system before making any wiring or refrigerant connections. Follow local mechanical and electrical codes, including NEC requirements for disconnect sizing and wire gauge at the outdoor unit. Do not attempt to substitute refrigerants or mix refrigerant types in the system.
