Rooftop systems offer a flexible way to provide treated air for one- to eight-story buildings. Many options and configurations are available to satisfy a wide number of applications. Fresh outside air is mixed with return air from the occupied space and then filtered, conditioned, and supplied back into the building. Conditioning involves cooling, dehumidifying, or heating the air for optimal space comfort. Rooftop units can serve a single zone, or an entire building filled with many zones. Some units can be designed specifically for make-up air, where only outside air is treated and sent to the space. Inverter compressors, beltless ECM fans, and energy recovery solutions make rooftop systems an easy-to-maintain, energy-efficient choice for conditioning any space. Heat produced by natural gas, electricity, hot water, steam, and heat pumps provides reliable heating for spaces with colder seasons and climates.


To meet and exceed demanding building performance criteria, our rooftop systems integrate advanced HVAC technologies including:

  • Variable speed inverter compressor
  • Variable speed heat pump
  • Direct-drive fans with variable speed ECM or VFD motors
  • Energy recovery wheel
  • Outdoor air monitor
  • Modulating hot gas reheat
  • MicroTech® III controls
  • SiteLine™ Building Controls
