I cleaned the condensate pans and drain lines and flushed with hot water to remove debris and to make sure they were draining properly. I operated each unit on second stage cooling and confirmed/ set the proper flow rate and confirmed heat of rejection and delta temperatures across the coil. The filters were in very good condition. I checked the electrical wiring and electrical systems, all were within specification except for the run capacitor for each unit. I replaced these and retained the original ones to return to WF. I recommended installing Intellistart Modules on each unit to help protect the compressors. Customer asked me to email a quote. Both units are operating normal.
