A VRF system in an office or showroom can have one outdoor unit and thirty indoor units, each a possible complaint. A VRF maintenance checklist recorded per unit address keeps the AMC visit complete and the customer's complaints down. Download the CSV and list every unit. Follow the maker's procedures.

ServicePilot keeps each outdoor and indoor unit as equipment on the site, creates AMC visits and stores the checklist on each job. See the HVAC maintenance checklist for AHUs and chillers and the AC AMC quotation format to price it.
