Variable Refrigerant Flow (VRF) is a smart heating and cooling system. It works like many small air conditioners connected to one big outdoor unit, with each indoor unit running at different speeds and temperatures.
Instead of cooling or heating the entire building, VRF sends the right amount of refrigerant to each room—saving energy and money while keeping everyone comfortable.
VRF systems are like having a personal climate control assistant for every room in your building.
Sensors check each room's temperature
Right amount of refrigerant sent to each indoor unit
Rooms reach perfect comfort levels
System only uses the energy it needs
