Dispatched our commercial HVAC technician to a business in Roseville CA, to investigate two units that were not cooling properly. Checked in with management and proceeded to troubleshoot. RTU#8 was running on fan only. Confirmed all electrical components sound, found circuit #3 low on refrigerant. Also found RTU#5 lower on refrigerant, but was able to repair same day and get #5 up and running. Will need to return and complete a full leak search and repair for unit #8.
