The GrandAire WJA5 Series is a compact and efficient 3-ton horizontal packaged air conditioner designed for attic, closet, slab-on-grade, or through-wall installations. Engineered to meet modern energy efficiency and environmental standards, it uses R-454B refrigerant, offering a significantly lower Global Warming Potential (GWP) than legacy systems while maintaining reliable cooling performance.
Built with a durable powder-coated steel cabinet and a rust-resistant composite basepan, this unit is ideal for residential and light commercial applications. The system is equipped with a single-stage scroll compressor and a direct-drive multispeed blower motor, delivering up to 36,000 BTU/h of cooling capacity with a 13.4 SEER2 rating, fully compliant with the 2023 DOE efficiency regulations.
Serviceability is streamlined with front and side access panels, and sound levels are kept low—down to 71 dBA with vibration isolation. Factory-installed features such as high- and low-pressure switches, a crankcase heater, and a filter drier ensure reliable, long-term operation with built-in safeguards.
The GrandAire WJA5 includes a 10-year limited parts and compressor warranty and a 1-year unit replacement guarantee when properly registered, providing homeowners and contractors peace of mind. Its horizontal airflow design makes it perfect for installations with space limitations or retrofits where vertical discharge is not an option.
