Griffmech specializes in VRF service and installation

Variable Refrigerant Flow (VRF) systems are rapidly becoming the future of HVAC for commercial and mixed-use buildings because they deliver unmatched energy efficiency, design flexibility, and precise comfort control. Unlike traditional systems that condition entire zones the same way, VRF technology modulates refrigerant flow to match each space’s exact heating or cooling demand—resulting in lower energy consumption and significantly reduced operating costs. Their compact equipment footprint and ability to run long refrigerant piping allow architects and engineers greater freedom, especially in renovation or space-limited projects. VRF systems also support simultaneous heating and cooling, making them ideal for buildings with diverse occupancy and load patterns. With rising energy standards and growing demand for sustainable, high-performance buildings, VRF stands out as a smart, future-proof solution for modern HVAC design.

Invented by Daikin in Japan in 1982 and common throughout Europe and Asia, VRF systems can efficiently and simultaneously heat and cool separate spaces in the same building for energy savings of 30% or more over traditional HVAC systems.

VRF systems utilize inverter-driven compressors to modulate the flow of heated or cooled refrigerant to individual units for on-demand comfort control. Significant energy savings are obtained through the ability to operate only at the needed flow rate, and by utilizing heat absorption output from one cooled space to provide heating for another. Large distribution fans are not needed in VRF systems, nor are chillers, boilers, piping, and pumps. Ductwork needs are minimal or eliminated altogether. VRF systems are extremely quiet, flexible, and provide superior load matching for increased comfort and dehumidification.

There are four main types of VRF systems: cooling-only, heat pump, heat recovery, and water source. A growing numbers of building owners are opting for VRF on new construction projects, and the technology is also a popular choice for retrofit applications when space is limited or where architectural or aesthetic integrity must be preserved.

Griffmech is expert in VRF service and installation and can help owners considering installing a variable refrigerant system assess their building’s specific needs. For more information on VRF, email Service@griffmech.com or call 609-388-1978
