Customized Direct Expansion Air Handling Unit & Rooftop Packaged Air Conditioners refers to rooftop AC units or rooftop air conditioners that are often part of commercial HVAC systems. They are designed to provide cooling/heating, proper ventilation, and air conditioning throughout large buildings. 

Rooftop HVAC units are installed on the roof to better save valuable indoor space and provide optimized  climate control. Often, these heating and cooling units can be seen on the roof of commercial properties. 

Customized Direct Expansion AHUs & Rooftop systems offer a flexible way to provide treated air for big space 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.

Customized Direct Expansion AHUs & Rooftop HVAC units can serve a single zone, or an entire building filled with many zones. Some rooftop 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 HVAC systems an easy-to-maintain, energy-efficient choice for heating and cooling any space. Heat produced by natural gas, electricity, hot water, steam, and heat pumps provides reliable heating for spaces with colder seasons and climates.
