The different types of commercial HVAC systems

Commercial HVAC systems can be very complex compared to their residential counterparts. To make your decision simpler, remember that they typically come in these three categories:

Below we will explain each one’s functions, as well as their pros and cons.

Single-Split Systems

This system is typically the best fit for smaller commercial spaces, restaurants, and shops. In general, it will come with an air conditioner and furnace to disperse air throughout your building, and a thermostat controls the temperature.


  • Affordable.

  • The ability to both heat and cool.


  • All indoor units require an outdoor unit, which means this can take up a lot of space.

  • Not as energy-efficient as other systems.

Multi-split systems

The main difference between the single-split and multi-split system is that these outdoor units can connect to multiple indoor units. These systems waste less energy since it heats and cools without the use of ducts. These heat pump systems work by transferring heat between the air inside a building to the air outside.


  • You can save outdoor space with fewer units.

  • Less drying than traditional furnaces.

  • Extremely energy-efficient.

  • Lower operation cost compared to other systems.


  • They typically have a higher installation cost.

VRF systems

Variable refrigerant flow systems are great for both large and small commercial buildings. They offer powerful, effective, and customizable heating and cooling to your space without the use of ducts.


  • Simultaneously heat and cool different parts of a building.

  • Runs at peak efficiency.

  • Sleek and aesthetically pleasing units.

  • Quick installation.


  • Installation costs can be higher.
