What Types of Commercial HVAC Systems Exist?

There are many types of commercial HVAC systems available today. As a building wner or manager, the different designs and variables can make it confusing to determine which is optimal for you.

What should you consider when shopping for an HVAC system for your commercial building?

To choose an HVAC system, you must consider many factors, such as building design. Some are more effective in larger buildings, and a one-room space may benefit from a different system than a space with many small rooms.

Other considerations include your budget and how long you expect the system to last.

HVAC Types, Advantages, and Disadvantages for Commercial Buildings

The sheer volume of choices can be daunting. For example, if you want a split system, do you need a single split system or a multi-split system? Read on for some helpful guidance.

Single-split System

A single split HVAC system has one compressor, an evaporator coil, a furnace, and a refrigerant.

Who it’s right for: Because they heat and cool individual rooms, single split systems are effective for smaller commercial buildings.

What it’s not designed for: Single-spilt systems are not designed for larger buildings with multiple rooms.


Multi-split System

A multi-split system operates similarly to a single one, except that multiple units hook up to a single outdoor unit.

Who it’s right for: These are best for large commercial properties.

What’s it’s not designed for: These systems are not meant for small commercial spaces.


Variable Air Volume (VAV)

VAV systems create constant, comfortable temperatures by varying airflow.

Who it’s right for: VAVs are ideal for multi-room spaces, as they allow separate rooms to have different temperatures.

What it’s not designed for: VAVs are not for single space buildings.


Variable Refrigerant Flow (VRF)

VRF systems move refrigerants to the zone within a building that needs to be heated or cooled.

Who it’s right for: VRF systems are suitable in a variety of commercial spaces, including mixed-use facilities.

What it’s not designed for: They are not meant for larger indoor assembly spaces.


Constant Air Volume (CAV)

CAVs provide constant airflow and regulate the building’s climate by adjusting the air supply temperature.

Who it’s right for: CAVs work best in spaces with large open areas and few windows, such as an exhibition hall.

What it’s not designed for: Buildings with multiple heating and cooling zones are not optimal for CAVs.


Heat Pump

A heat pump can provide heating and cooling by removing heat from the air and moving it inside or outside, depending on whether a building needs to be heated or cooled.

Who it’s right for: Heat pumps work well in various settings such as schools and sports facilities.

What it’s not designed for: Heat pumps are not intended for colder climates with temperatures below 40 degrees.
