Weekly HVAC System Maintenance Checklist

*Check the temperatures of cold stores.

*Check evaporator and condenser coils for dirt or debris and clean them if required. Also, check for missing or plugged nozzles.

*Regularly check the entire piping system, especially joints, seals, valves and glands for leaks.

*Check the refrigerant sight glass for bubbles. Bubbles in the sight glass often mean a system is leaking. Find the leaks and repair them before the system is recharged with refrigerant.

*Report and repair any vibrating pipe work, as this is likely to cause a leak over time.

*Check that compressor oils are at the right level.

*Check that product is not impeding the air flow of evaporators.

*Ensure that fans, motors and belts have sufficient air circulation.

*Check for plugged line filters.

*Check evaporators are defrosting and pan lines are clearing properly.

*Report ice on the floor and walls of cold rooms as this indicates that excessive air is entering the room, which becomes a defrosting and safety problem.

*Check usage procedures.
