YORK Sun Choice Ultra High-Efficiency Rooftop Unit

November 1, 2022

The 12.5- to 23-ton YORK Sun Choice Ultra High-Efficiency Rooftop Units (RTU) surpass DOE 2023 standards by up to 45%, delivering the highest part-load efficiency in their class.


Efficiency is achieved using a combination of Copeland™ high-efficiency ZPKZ fixed-speed, ZPS two-stage and ZPV variable-speed compressor technologies and ECM outdoor fan motors. A convertible filter rack with MERV 13 filters, demand control ventilation and economizers with modulating power exhaust are available to meet stringent indoor air quality (IAQ) requirements. Multiple airflow strategies – including variable air volume and exclusive IntelliSpeed™ discrete fan control with variable capacity control –improve temperature and humidity accuracy to deliver maximum occupant comfort. A direct-replacement footprint streamlines specification and minimizes installation costs. 


Choice rooftop units are designed and tested in the Johnson Controls Advanced Technology Lab located in Norman, Oklahoma, and supported by factory-backed warranties, including a 1-year parts warranty, 5-year compressor and electric heat limited warranties, 10-year aluminized heat exchanger limited warranty and a 15-year stainless steel heat exchanger limited warranty.
