Weatherking WP14AY60AJ2NA Heat Pump 5 Ton 14.3 SEER2

Product Description

The WEATHERKING WP14AY60AJ2NA is a two-stage residential heat pump rated at 60,000 BTU/h (5 tons) of cooling capacity with a 14.3 SEER2 efficiency rating. It operates on R454B refrigerant, a lower-GWP alternative that meets current regulatory requirements for new equipment. The two-stage compressor allows the unit to run at partial load during moderate conditions, reducing runtime cycling and improving indoor comfort and humidity control. Licensed HVAC technicians handle installation and commissioning of this equipment.

This unit is sized for larger residential applications or light commercial spaces requiring 5-ton cooling and heating capacity. It is designed for split-system configurations paired with a compatible indoor air handler or furnace coil. The 14.3 SEER2 rating reflects performance under SEER2 test conditions, which use a higher external static pressure than legacy SEER testing. Systems in this class are common in warmer climate zones where heat pump efficiency is a primary design consideration.

Key Features

• 60,000 BTU/h (5-ton) cooling capacity for larger residential or light commercial loads
• 14.3 SEER2 efficiency rating meets current federal minimum efficiency standards
• Two-stage operation reduces short cycling and improves dehumidification at part load
• R454B refrigerant complies with current low-GWP refrigerant regulations

Compatibility

Designed as an OEM-style replacement or new-install outdoor heat pump unit for split-system residential or light commercial HVAC applications requiring a 5-ton, R454B-compatible heat pump.

Installation Notes

Installation must be performed by a licensed HVAC technician holding an EPA Section 608 certification, as this unit uses regulated refrigerant. Disconnect and lock out all electrical power before any service or connections are made. Follow local mechanical and electrical codes, including NEC requirements for disconnect sizing and wiring methods. Verify indoor coil and air handler compatibility for R454B refrigerant before installation.
