Performed commercial HVAC preventative maintenance on two split-system air conditioning units at Domino's Pizza in Manor, TX. Replaced all air filters, cleared condensate drain lines, checked refrigerant operating pressures, recorded supply and return air temperatures, and inspected electrical and mechanical components for proper operation. Replaced two run capacitors on the York condensing unit and one run capacitor on the Carrier condensing unit. Both systems exhibited normal refrigerant pressures and proper temperature splits following maintenance. Also responded to an emergency walk-in cooler service call after the cooler lost temperature. Upon arrival, found the electrical disconnect switched off. Restored power, monitored system operation, and verified the walk-in cooler pulled down to the proper operating temperature before leaving. Observed a flashing liquid-line sight glass indicating the refrigeration system remains low on refrigerant, confirming an active refrigerant leak. Recommend scheduling a leak search and repair to prevent continued refrigerant loss, additional service calls, and potential product loss.
