If you’re a business owner or manager in South Florida, you know how important it is to keep your customers and employees comfortable. But with so many options available, it’s tough to figure out which type of air conditioning system is right for your space.

In this article, we’ll talk about two popular types of commercial air conditioning units: Rooftop and Split System units. We’ll explain how each works, the pros and cons of each, and which one might be best suited for your business.

So, whether you’re looking to upgrade your current AC system or starting from scratch, read on to learn more about these two systems and discover which one is right for you.

Commercial Air Conditioning Systems: Rooftop & Split System Units

The two main types of systems are rooftop or packaged systems and split unit systems. A rooftop system is referred to as a packaged system because all the components are in a single machine. A split unit is so-called because the condenser is separate from the blower or head unit. Often the condenser is located outside, although indoor installation is possible.


Rooftop units are typically installed on the roof of a commercial building, making them easier to access and maintain. On the other hand, split system units can be installed either inside or outside the building, requiring more design and preparation.

Due to roof installation, rooftop systems offer more space inside the building. Installers can easily hide ducting work under suspended ceilings.

Since split units are often installed on the sides of buildings, accessing installation areas can be more complicated, especially on multi-story buildings.


All commercial air conditioning systems should have regularly scheduled maintenance plans. Rooftop units are designed for easy access making it easier to perform regular maintenance. Split system units, on the other hand, require more specialized maintenance but both systems need an experienced AC technician to perform regular maintenance.


Rooftop units tend to be larger and heavier, making them suitable for cooling larger commercial spaces. A rooftop unit is also preferable where different areas have different cooling requirements. The unit on the roof can handle the cooling while the control panel is installed in the rooms, allowing users to tailor each room’s condition.

Split system units are smaller and more lightweight, making them ideal for smaller spaces such as retail stores and small offices.

Cooling Capacity

Rooftop units generally have a higher cooling capacity. This makes them ideal for larger commercial buildings such as warehouses and manufacturing facilities.

Split system units, on the other hand, have a lower cooling capacity. They are better suited for smaller commercial spaces like retail stores, cafés, and small offices.

Commercial AC Unit Options

Overall, the choice between rooftop and split system units will depend on a variety of factors. These may include the size of your commercial space, budget, and cooling needs.

It’s important to weigh the pros and cons of each type of unit and consult with an experienced commercial AC company to determine which one is the best fit for your business.
