VRF / VRV System Installation in San Jose, CA
Need precise temperature control across multiple zones? VRF/VRV systems deliver flexible, efficient comfort for homes and offices.
VRF / VRV Systems in San Jose & the Bay Area
Variable Refrigerant Flow (VRF — Daikin calls it VRV) is the gold standard for buildings that need independent temperature control in many rooms at once: offices, medical suites, multi-family buildings, and large custom homes across San Jose and Silicon Valley. Instead of blasting one temperature everywhere, a VRF system continuously modulates refrigerant to each zone — some spaces can heat while others cool, simultaneously.
Promax designs and installs Mitsubishi CITY MULTI and Daikin VRV systems from load calculation through commissioning. Our factory-trained team handles branch controllers, heat-recovery piping, controls integration, and the permits — delivering 30–40% energy savings over conventional rooftop systems with far better comfort.

Frequently Asked Questions
What's the difference between VRF and VRV?
They're the same technology — VRV is Daikin's trademarked name (Variable Refrigerant Volume); every other manufacturer calls it VRF (Variable Refrigerant Flow). We install both Daikin VRV and Mitsubishi CITY MULTI VRF systems.
Is VRF worth it for a house, or only commercial buildings?
For larger homes (3,500+ sq ft), homes with in-law units, or owners who want true room-by-room control, VRF is excellent. For most single-family San Jose homes, a multi-zone ductless system delivers similar benefits at lower cost — we'll recommend honestly which fits your building.
How much energy does a VRF system save?
Compared to conventional rooftop or split systems, properly commissioned VRF typically cuts HVAC energy use 30–40%, thanks to inverter compressors and zone-level modulation. Heat-recovery VRF saves even more by moving heat between zones instead of rejecting it outside.
