Commercial Rooftop HVAC systems

Commercial HVAC rooftop unit offer a convenient way to provide cooled or heated air for one to eight-story buildings. Many systems and configurations are available to satisfy a wide number of applications. Fresh outside air is mixed with return air from the occupied space and it’s then filtered, conditioned, and supplied back into the building. Conditioning involves cooling, dehumidifying, or heating the air for optimal space comfort.

Rooftop heating units can serve a single zone, or an entire building filled with many zones. Some units can specifically design for make-up air, treating only outside air and sending it to the space. Commercial rooftop heating systems are easy-to-maintain and are energy-efficient system for conditioning any space. Natural gas, electric, hot water, steam, and heat pump heat provide reliable heating for spaces with colder seasons and climates.

  • Poor airflow making certain rooms in your building too hot, cold, or humid
  • Loose or worn-down fan belts that decrease overall HVAC efficiency

  • Worn-out contractors that need replacing
  • Dirty coils that impact the system’s performance and create poor indoor air quality
