Johnson Controls Unveils Expanded Line Of Choice Rooftop Units That Surpass Department Of Energy (DOE) 2023 Efficiency Standards

Johnson Controls, the globally renowned company for smart, healthy and sustainable buildings, has launched the newest development in the Choice line of commercial rooftop units (RTUs) available from Johnson Controls®, YORK® and TempMaster®.

The 12.5- to 27.5-ton RTUs (rooftop units) surpass aggressive Department of Energy (DOE) 2023 efficiency standards by 6-45%, depending on the efficiency level, while maintaining an economical advantage.

New product line of Choice RTUs

We've elevated the proven performance of Choice rooftop units with enhanced features and options"

Available in high-efficiency, ultra-high-efficiency and heat pump models, Choice RTUs can be configured for cooling only, staged-gas heating, modulating-gas heating and now heat pump operation, in conjunction with factory-installed electric heating to provide the flexibility necessary, in order to help building owners reach current evolving efficiency requirements.

“We've elevated the proven performance of Choice rooftop units with enhanced features and options to help our customers achieve their sustainability goals,” said Jason Carter, Senior Product Manager, Ducted Systems, Johnson Controls, adding “We’ve elevated the proven performance of Choice rooftop units with enhanced features and options to help our customers achieve their sustainability goals.”

He continues, “Building operators now have even more options to reduce energy consumption and deliver cost savings based on the unique needs of their facility.”

Choice Rooftop Unit Options Include:

• High-efficiency Choice rooftop units: Available in dedicated downflow (15-27.5 tons) or sideflow (15-25 tons) configurations. Provide up to 23% greater part-load efficiency than our legacy comparable, standard-efficiency units. They surpass aggressive Department of Energy (DOE) 2023 efficiency standards by almost 10%.
• Ultra-high-efficiency Choice rooftop units (12.5-23 tons): Leverage a combination of Copeland™ high-efficiency ZPKZ fixed speed, ZPS two-stage, and ZPV variable-speed compressor technology to deliver the highest part-load efficiency in their class. They surpass Department of Energy (DOE) 2023 efficiency standards by up to 45%.
• Heat pump Choice rooftop units (12.5-25 tons): Deliver up to 13% higher IEER than competitive units and meet DOE 2023 efficiencies for both heating and cooling using mechanical and electric heat instead of gas combustion to support sustainability and decarbonization. They surpass Department of Energy (DOE) 2023 efficiency standards by up to 6%.

Feature a convertible filter rack with pleated filters

All Choice rooftop units feature a convertible filter rack with pleated filters up to MERV 13 available

All Choice rooftop units feature a convertible filter rack with pleated filters up to MERV 13 available as a factory option, in order to help meet LEED requirements.

Multiple airflow strategies – including variable air volume (VAV), exclusive IntelliSpeed™ discrete fan control (DFC) with 2-stage and 4-stage options and Continuous Reset Single Zone (CRSZ) control – help to improve ventilation based on building requirements.

Choice rooftop units support IAQ performance

Additionally, the units are compatible with a full suite of system accessories to further support indoor air quality (IAQ) performance.

In addition to operational cost-savings achieved through system efficiencies, Choice RTUs are designed to lower initial project costs as well. The lightweight design streamlines specification by reducing building design requirements and eliminating the need for additional structural engineering analysis when used in replacement applications.

Choice RTUs are digitally enabled to further enhance efficiency

Choice rooftop units are digitally enabled to further enhance efficiency, reduce operational costs and extend equipment life. This also provides seamless integration with building control systems, including Verasys®.

Johnson Controls® Choice, YORK® Sun™ Choice and TempMaster® Omni™ 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.
