Comfort and Economy on a Floor-by-floor Basis

Maintaining a constant temperature, purity and humidity of air is essential for ensuring a stable environment for critical electronic and computer equipment, this is why there is the need for close control air conditioning.

Unlike comfort air conditioning, close control systems must operate constantly 24/7 requiring high reliability and minimal power consumption.

Johnson Controls knows that no two close control requirements are the same, this is why the YORK® range of custom close control units offers quiet, compact and energy efficient equipment that can be configured to needed requirements.


Achieve reliability and minimal power consumption for close control systems which are operating constantly.


Tailor your close control systems based on the exact requirements within each part of your building.


Choose quiet, compact, energy-efficient systems to secure efficacy in your space.
