The YORK Sun Premier Commercial Rooftop Units (RTUs) by Johnson Controls are designed to reduce carbon emissions and drive sustainability while reducing operational and maintenance costs for buildings. With a portfolio ranging from 25 to 150 tons, the Premier RTUs exceed the Department of Energy’s 2023 energy efficiency standards. Most tonnages meet the Consortium for Energy Efficiency (CEE) 2024 highest tier ratings.
Offered in standard efficiency, high capacity, or high efficiency, Sun Premier units provide up to 31% greater efficiency at part-load than is required, depending on the standard. The units combine variable-speed compressor options, variable-speed drive fans, and low-GWP R-454B refrigerant with advanced airflow and heat transfer technologies for highly optimized operation.
