3 Most Common Types of Commercial HVAC Systems

Commercial HVAC Systems

HVAC or heating, ventilation and air conditioning is designed to control the indoor environment by providing a temperate space with the purest air possible. A properly installed HVAC system will control the indoor humidity, provide even heated or cool air when needed, provide good ventilation, including indoor air quality, and some systems may provide smoke removal. A great commercial HVAC system is key to having content employees and happy customers alike.

There are many applications that utilize commercial HVAC systems, such as retailers, manufacturing or distribution companies, hospitals, office buildings, schools and storage facilities, to name a few. While there are several choices when it comes to commercial HVAC systems, three stand out as the most common: Single-Split, Multi-Split or VRF or VRV systems. 

What Are the Differences?

Let’s take a brief look at what each system is and how they meet the needs for a commercial HVAC system.


The single-split system works well in small commercial spaces made up of individual rooms. It allows the temperature to be controlled independently in each room, which is a plus, but the major drawback is that it requires one indoor unit and one outdoor unit per room. You can see this system would take up a lot of outdoor space.


Multi-split commercial HVAC systems consist of one outdoor unit that connects to multiple indoor units. Depending on the manufacturer, some outdoor units can handle up to 10 indoor units. The upfront installation costs for a multi-split system can be higher depending on the total number of indoor units, but it offers a lot of versatility inside. Each indoor unit allows for individual control of temperature and with one outdoor unit, less space is needed outside.

VRF or VRV Systems

The Variable Refrigerant Flow (VRF) or Variable Refrigerant Volume (VRV) commercial HVAC system is more sophisticated than the others. The terms VRF and VRV are interchangeable and just two different ways to describe the same system. This type of commercial HVAC system works best in a large building that requires customized heating and cooling over multiple zones like a restaurant, hospital or a factory. These systems have gained popularity in the U.S. over the last 10 years. They can be expensive to install but overtime can afford maximized energy savings.
