What is a VRF System

Variable Refrigerant Flow is a ductless, dual-action climate system that is ideal for heating and cooling spaces without excessive mechanical installation. VRF systems allow multiple indoor units to operate on a single system and are able to heat and cool separate rooms simultaneously. One system that can heat some rooms and cool others while consuming a fraction of the energy needed is highly beneficial for tenants and property managers alike.


VRF technology uses inverter systems to enable compressors to either ramp up or down, depending on the need of each room or space, to reduce the amount of energy spent affecting the temperature. Traditional, non-inverter systems are typically running at full capacity continuously, expending more energy than needed. The design and installation of VRF systems are customizable and easier to retrofit into buildings due to the lack of physical space needed for forced air ducts, making them an optimal choice for large, multi-tenant buildings like offices, hotels, and apartment complexes, schools, and even common residential homes. Get in touch with our team to see if a VRF system is the right fit for your building.

VRF System Advantages

VRF systems offer several advantages over traditional DX split systems. They offer a higher level of energy efficiency. Unlike traditional systems, which cycle on and off, a VRF system can operate continuously at part-load, resulting in a significantly higher overall operating efficiency.


VRF systems can be equipped with heat recovery, which allows heat extracted from one space to be used to condition other spaces in the system that are in need of heat and vice versa, increasing the overall system efficiency.


VRF systems are typically smaller and lighter weight than their DX counterparts, making them easier to install and transport, as well as preserving precious ceiling heights and floor space. VRF systems offer a wide range of configurable options, allowing users to tailor the system to their specific needs.


VRF systems in Easthampton, MA offer longer refrigerant piping run lengths and greater refrigerant “lift” heights. They use a variable-speed compressor to deliver the appropriate amount of refrigerant to the indoor units at any time. This allows for longer piping lengths, as the compressor can adjust the volume of refrigerant flow, delivering the right amount of refrigerant at the appropriate pressure over greater distances.


As a result, VRF systems are more flexible and more efficient than traditional split systems and can provide greater comfort and better indoor air quality to the building occupants.
