LG Multi V Cross-Reference & Unit Pricing - VRF Replacement Systems by LG
Building a Multi V system? Mix and match any indoor units with any outdoor unit — no fixed kits. Two rules: voltage must match the outdoor unit, and total connected indoor capacity can typically be up to 120% of the outdoor unit’s rated capacity. Model numbers in red are in our online store — click to order (restrictions apply). Gray models are the older generations each unit replaces. R-32 models marked “Call” are available by phone while we finish listing them online. Units are only available to authorized contractors in applicable areas.
