Rooftop HVAC units (RTUs) are a common sight on the roofs of malls, hospitals, schools, and other flat-roofed buildings. These systems are designed to withstand all weather conditions, from freezing winters to scorching summers. Efficient and unobtrusive, RTUs excel at heating and cooling large spaces, making them ideal for commercial buildings.

What Is a Rooftop HVAC Unit? 

These systems function similarly to ground-level and indoor HVAC units, with the primary difference being that they are installed on the roof. Commercial buildings with flat roofs often opt for rooftop HVAC systems because they do not occupy valuable indoor space. Additionally, their noise levels are low enough that people inside the building cannot hear them, adding to their appeal.

How Does it Work?

Rooftop HVAC units provide heating and cooling in a few key steps: 

• Fresh air enters the RTU through the air hood or economizer on the side of the unit. Air hoods prevent snow and rain from entering while allowing air intake.
• Inside the RTU, the fresh air mixes with the return air and moves into the system’s filters, where contaminants are removed before being released.
• After filtration, the fresh air is cooled or heated.
• Once the air reaches the desired temperature, the fan circulates it through the building ducts.

How Do They Differ From Others? 

Rooftop HVAC systems distinguish themselves in two key ways: first, they are installed on the roof, which offers numerous benefits. Second, they are considered “package units” because they provide both heating and cooling from a single unit. In contrast, standard HVAC systems typically require separate components for heating and cooling, lacking an RTUs level of convenience.

Why Choose a Rooftop HVAC?

Space-saving: Commercial buildings need large HVAC systems to ensure a comfortable interior temperature. With rooftop HVAC, valuable space is saved.

Enhanced security: Ground-level HVAC units are vulnerable to theft and vandalism. Rooftop HVAC units, however, offer enhanced security as they can only be accessed with a key, adding an extra layer of protection.

Quiet operation: Since all components of the RTU are located outside the building, there are no disruptive noises for those inside the building.

Easy maintenance: With all components housed in a single unit, HVAC technicians can easily access the RTU for maintenance and repairs.

Energy efficiency in newer models: Newer models are now much more energy-efficient, performing their functions without significantly increasing costs.
