Variable refrigerant flow (VRF)

Variable refrigerant flow is an HVAC technology that uses refrigerant to condition the air using an outdoor condensing unit connected to multiple indoor units within a building. The outdoor unit has a variable speed compressor to modulate the flow of refrigerant through the evaporator coils in the indoor units. These can be 2-pipe (Heat Pump) or 3-pipe (Heat Recovery) systems.

PSE offers $1.00 per square foot of conditioned space for VRF systems.

To get started, fill out an application and email it to grantapplications@pse.com. A PSE engineer will contact you to discuss the project.

How to qualify:

  • Your building must have a minimum of 10,000 square feet of conditioned space
  • This grant is available for retrofit & new construction
  • This grant is available to commercial offices & schools
  • Condenser units must serve multiple zones & have rated cooling capacity greater than or equal to 5 tons.
