Air Conditioning Commissioning Checklist

1. Access eAuditor Audits & Inspection:

• Open the eAuditor Audits & Inspection app on your device.
• Log in with your credentials.

2. Create a New Template:

• Go to “Templates” in the eAuditor Audits & Inspection app.
• Click on “Create Template” or “New Template” to start building your checklist from scratch.

3. Design the Air Conditioning Commissioning Checklist:

• Title the Checklist: Name your checklist something like “Air Conditioning Commissioning Checklist.”
• Sections: Divide the checklist into sections that correspond to different stages or components of the AC system.

4. Add Checklist Items:

• For each section, add specific checklist items. Below are some examples:

Section 1: Pre-Commissioning Inspection

• System Components: Verification of installation of all components (condenser, evaporator, air handler, etc.) in good condition.
• Electrical Connections: Check all electrical connections for tightness, correct wiring, and secure connections.
• Ductwork: Ensure correct installation, sealing and insulation of ductwork as required.
• Refrigerant Lines: Inspect refrigerant lines for proper installation, insulation, and any signs of damage or leaks.
• Drainage: Check for correct installation and free flow of condensate drains without obstructions.

Section 2: Initial Startup

• Power Supply: Confirm supply of correct voltage and phase to the unit.
• Thermostat Settings: Verify for correct  installation, programming, and functioning of the thermostat.
• Refrigerant Charge: Check the refrigerant charge according to manufacturer specifications.
• System Pressures: Record and verify system pressures (suction and discharge) during operation.
• Airflow: Measure and verify airflow rates across the evaporator and condenser coils.

Section 3: Operational Checks

• Cooling Performance: Test and verify that the system provides sufficient cooling as per design specifications.
• Fan Operation: Confirm that all fans (indoor and outdoor) are operating correctly and at the correct speeds.
• Temperature Differentials: Measure and record the temperature difference between supply and return air.
• Noise Levels: Assess and document the noise levels of the system during operation.
• Vibration Check: Ensure that there are no excessive vibrations in the system during operation.

Section 4: Control System Checks

• Control Settings: Verify that all control settings (temperature setpoints, schedules) are correctly configured.
• Safety Controls: Test and confirm the operation of all safety controls (high-pressure switches, low-pressure switches, etc.).
• Defrost Cycle: If applicable, check the operation of the defrost cycle in heat pump systems.
• Economizer Operation: Verify the operation of the economizer, if installed, and ensure proper functioning.

Section 5: Final Inspection and Documentation

• System Labels: Ensure that all labels and tags (e.g., refrigerant type, safety warnings) are in place and legible.
• Final Cleanup: Verify that the area around the unit is clean, and all debris from installation is removed.
• Documentation: Confirm that all commissioning documentation (warranties, manuals, commissioning reports) is complete and provided to the client.
• Client Handover: Verify for briefing of the client on system operation, maintenance, and warranty procedures.

5. Set Up Responses and Logic:

• For each checklist item, set up response types (Yes/No, Pass/Fail, N/A).
• You can also add conditional logic to trigger follow-up questions or actions if an item fails.

6. Add Notes and Attachments:

• Allow space for notes or comments under each checklist item.
• Include the option to attach photos or videos as evidence for each checklist item.

7. Assign and Share the Checklist:

• Once your template is complete, save it and assign it to relevant team members.
• Share the template with your team or export it for use in your commissioning process.

8. Use the Checklist During Commissioning:

• During the commissioning process, use the checklist to ensure all tasks are completed to standard.
• Complete the checklist on your device, making sure to check off items, add notes, and attach any relevant photos.

9. Review and Export the Completed Checklist:

• After completing the commissioning, review the checklist to ensure all items have been addressed.
• Export the completed checklist as a PDF or share it directly with your team or client.

10. Continuous Improvement:

• Regularly review and update the checklist template based on feedback and experiences to ensure it remains relevant and effective.

This checklist ensures that all necessary steps are taken during the commissioning of an air conditioning system, promoting reliable performance, safety, and client satisfaction. By following this structured approach, you can systematically verify that the AC system is installed and operating correctly before it is handed over to the client.
