VRF (Variable Refrigerant Flow) or VRV (Variable Refrigerant Volume) systems, like ductless mini-splits, use refrigerant as the cooling and heating medium. This refrigerant is conditioned by a single outdoor condensing unit, and is circulated within the building to multiple indoor units.

How do VRF and HVAC Systems Differ?

VRF systems vary from their counterparts in a few key ways. Where conventional HVAC systems heat or cool the air prior to distributing it throughout your ductwork and home, VRF systems send air directly to the air handler inside prior to conditioning. Once the air reaches the air handler it is then heated or cooled and dispersed directly into that zone. Because of the unique zoning technology, VRF systems have the ability to heat one zone while simultaneously cooling another. 

The VRF systems also do not require ductwork, instead they utilize pipe systems to transport the refrigerant needed to condition the space. This gives VRF systems a tremendous amount of flexibility – far superior to the other systems in the HVAC industry. They are also much easier to install, design, and configure when adding on to your home or business space. Rather than finding out how to redesign the ductwork and redo load calculations, VRF systems require a simple change of adding another air handler to the new space.


Benefits of VRF Technology:

  • Quiet operation
  • Energy efficient
  • Minimal energy loss
  • Green technology
  • Multiple zoning options per outdoor unit
  • Simultaneous heating and cooling
  • No ductwork needed
  • Architectural design flexibility
  • Space saving: smaller outdoor unit


VRV systems were created by Daikin in 1982, this technology, while newer to the market, has been around and continually improved for decades. Daikin has improved on this system in order to help owners save space, energy, and money.
