A walk-in cooler can be cooling properly and still need attention in places that are easy to overlook. That was the case during a routine annual maintenance visit in Walterboro, SC. The client contacted our office to schedule service, and our Arctic Air Inc. technician worked through a full preventive maintenance inspection of the remote condensing unit and the indoor cooler components.
Most of the system checked out well.
The annual visit also uncovered two door-related items that needed follow-up: the bottom sweep gasket needed replacement, and the hinges needed spring cartridges so the door would close on its own every time.
That is exactly the kind of detail routine maintenance can bring to the surface.
Our commercial refrigeration work includes preventive maintenance and service for walk-in coolers and similar equipment.
Working Through the Annual Maintenance Plan
We use the maintenance visit to look at the refrigeration system as a complete operating setup, not a single component. On this Walterboro job, our checks included:
- Remote condensing unit: We checked the weather panels and hoods, refrigeration sight glasses, refrigerant charge, crankcase heaters, operating and safety controls, refrigerant lines, and fan motors. Each item checked OK. We also cleaned the condenser coils and noted the unit’s general condition as good.
- Indoor components: We cleaned the evaporator coils and evaporator fans, checked the operating and safety controls, and cleared the condensate drains and pans. The controls checked OK. Defrost heaters and controls were not applicable on this unit, and anti-sweat heaters were also not applicable.
- Door components: We inspected the gaskets, latches, hinges, and hardware. That portion of the inspection led us to the worn bottom sweep gasket and the hinge issue that required spring cartridges.
The maintenance record also documented the coil cleaning material used during the visit. Keeping those details with the service record gives our team a clear picture of what was checked, cleaned, and flagged for repair.
Returning to Correct the Door Issues
We returned to the Walterboro, SC job on August 7, 2026, to complete the quoted follow-up work. We removed the walk-in cooler door hinges and took out the original cams. In their place, we installed new spring cartridges and adjusted the spring tension.
After securing the hinges back to the door, we tested their operation. The hinges were working well and closing the door completely.
Next, we removed the old bottom sweep gasket. We installed the new sweep gasket with new screws, then tested the door again. It continued to close on its own as intended. With both repairs complete and the door operation confirmed, the job was finished.
