Weatherking WSA14AY30AJ1NA 2.5 Ton 14.3 SEER2 Condensing Unit

Product Description

The WEATHERKING WSA14AY30AJ1NA is a single-stage residential air conditioner condensing unit rated at 2.5 tons and 30,000 BTU/h of cooling capacity. Part of the Versus Line, it operates on R454B refrigerant and meets 14+ SEER2 efficiency requirements under current DOE standards. The unit runs on 208/230-volt, single-phase, 60 Hz power and uses a scroll compressor for reliable, low-maintenance operation. Maximum overcurrent protection is rated at 25 amps. The small-footprint platform makes this unit well suited for residential installations where equipment clearance or pad space is limited. Licensed HVAC technicians handle installation and commissioning.

This condensing unit is designed for residential split-system cooling applications. Its compact square footprint, measuring 27.63 inches in length by 27.63 inches in width, allows placement in tight side yards, courtyard installs, and retrofit scenarios where a standard-platform unit would not fit. The non-communicating control interface makes it compatible with conventional, non-proprietary thermostat and air handler wiring. The 74 dBA sound rating is within the typical residential equipment range. Liquid line outside diameter is 3/8 inch and suction line outside diameter is 3/4 inch.

Key Features

• 30,000 BTU/h cooling capacity at 2.5-ton nominal rating
• 14+ SEER2 efficiency rating compliant with current DOE regional standards
• R454B refrigerant — lower global warming potential alternative to R-410A
• Scroll compressor for quiet, efficient operation
• Small-platform footprint at 27.63 x 27.63 inches for space-constrained installations
• Non-communicating controls compatible with standard low-voltage thermostats
• 208/230-volt single-phase operation with 25-amp maximum overcurrent protection

Compatibility

Designed for use in residential split-system cooling or heat pump configurations requiring a non-communicating condensing unit on a small equipment platform. Match with a compatible evaporator coil and air handler rated for R454B refrigerant and 14+ SEER2 system performance. No specific model compatibility data was provided in the product input.

Installation Notes

Installation must be performed by a licensed HVAC technician certified to handle A2L refrigerants, as R454B carries a mild flammability classification requiring adherence to applicable local mechanical codes and ASHRAE 15 guidelines. Disconnect and lock out all electrical power at the disconnect box before making any wiring or refrigerant connections. Set the unit on a level concrete pad or approved equipment stand, verify adequate clearance on all sides per manufacturer specifications, and confirm line set sizing matches the 3/8-inch liquid and 3/4-inch suction line requirements before brazing. Do not use R-410A service equipment for R454B without verifying compatibility.
