Johnson Controls offers ultra-high-efficiency and heat pump RTUs

May 31, 2023  By  Anthony Capkun

May 31, 2023 – Johnson Controls’ Choice line of commercial RTUs (rooftop units) are available in high-efficiency, ultra-high-efficiency, and heat pump models. They can be configured for cooling only, staged-gas heating, modulating-gas heating and, now, heat pump operation in conjunction with factory-installed electric heating.

Available from Johnson Controls, York and TempMaster, the 12.5- to 27.5-ton RTUs surpass U.S. Department of Energy 2023 efficiency standards by 6% to 45%, says Johnson, depending on the efficiency level.

All Choice RTUs feature a convertible filter rack with pleated filters up to MERV 13 available as a factory option to help meet LEED requirements, says the company. Multiple airflow strategies—including variable air volume (VAV), IntelliSpeed discrete fan control with 2- and 4-stage options and Continuous Reset Single Zone control—help to improve ventilation based on building requirements.
