Learn what a rooftop unit is, how it’s used in commercial HVAC, and its advantages and disadvantages.
Quick Facts
A rooftop unit (RTU) is a self-contained heating, ventilation, and air conditioning (HVAC) system that’s typically installed on the roof of a building but can also be installed on the ground. Rooftop units are common solutions for commercial buildings and are sometimes used in residential settings. They are designed to provide conditioned air to the interior of the building by connecting directly to the building’s ductwork.
Rooftop units work by drawing in air, conditioning it (heating, cooling, and filtering), and then distributing it through ductwork into the building. Here’s a step-by-step breakdown of the process:
A packaged RTU in HVAC contains all its components, including the compressor, condenser, evaporator coil, and blower fan, in one compact box. This “packaged” design simplifies installation and maintenance.
