Holiday Shutdown Checklist: Preventative Maintenance For Your Compressor System

Holiday shutdowns are a welcome break for staff, but they can be a risky time for compressed air systems if they’re not properly prepared. A little preventative maintenance before locking the doors can help avoid costly repairs, unexpected downtime, and energy waste when operations resume. Whether your facility shuts down for a few days or several weeks, use this checklist to keep your compressor system protected and ready to go.

1. Perform a Visual System Inspection

• Check for visible oil, air, or condensate leaks

• Inspect hoses, fittings, and piping for wear or corrosion

• Look for loose electrical connections or damaged wiring

• Confirm guards, covers, and safety labels are intact

Catching small issues now can prevent major failures later.

2. Check Oil Levels and Oil Condition

• Verify oil levels are within manufacturer specifications

• Check oil colour and consistency for signs of contamination

• Top up or change oil if service intervals are approaching

• Inspect oil filters and replace if nearing end of life

Fresh, clean oil helps protect internal components during idle periods.

3. Drain Condensate Completely

• Drain all compressor tanks and air receivers

• Empty condensate traps and dryers

• Inspect automatic drains to ensure proper operation

• Check for freezing risk in unheated areas

Standing moisture can lead to corrosion, bacterial growth, and freeze damage.

4. Inspect Air Dryers and Filtration

• Check dryer performance indicators and alarms

• Inspect pre-filters and after-filters for clogging

• Replace filter elements if they’re close to service limits

• Confirm desiccant dryers are functioning properly

Clean, dry air protects downstream equipment during startup after the shutdown.

5. Clean Cooling Systems

• Clean coolers, heat exchangers, and ventilation grills

• Remove dust, debris, and oil buildup

• Verify cooling fans are operational

• Ensure adequate airflow around the compressor

A clean cooling system helps prevent overheating when production restarts.

6. Review Belts, Couplings, and Moving Parts

• Inspect belts for cracks, glazing, or improper tension

• Check couplings and alignment

• Lubricate bearings and moving parts where applicable

• Note any components that may need replacement soon

Addressing wear before shutdown avoids startup failures later.

7. Verify Controls and Safety Devices

• Test emergency stops and safety shutdowns

• Check pressure switches and sensors

• Review alarm history and clear resolved faults

• Confirm control settings are correct for restart

Reliable controls ensure a smooth and safe return to operation.

8. Shut Down Properly

• Follow manufacturer-recommended shutdown procedures

• Allow compressors to cool before powering off

• Isolate power if the system will be down long-term

• Close air valves if required

Proper shutdown protects internal components and electronics.

9. Document and Schedule Follow-Up

• Log maintenance tasks completed

• Note any issues requiring attention after the holidays

• Schedule post-shutdown inspections or service visits

• Ensure restart procedures are documented and accessible

Planning ahead reduces surprises when staff return.

A holiday shutdown doesn’t have to mean holiday headaches. Taking a proactive, preventative maintenance approach helps extend equipment life, improve efficiency, and ensure your compressed air system is ready to perform when production resumes.

If you’re unsure about any part of your shutdown process, or want professional support, now is the perfect time to schedule a service check before the holidays begin. Call NCA Ltd. today to make sure you’re ready for holiday shutdowns.
