Perform AC Inspection using eAuditor
AC Inspection refers to the systematic examination and testing of an air conditioning (AC) system to ensure it operates efficiently, safely, and reliably. This inspection typically covers components such as compressors, condensers, evaporators, refrigerant levels, electrical connections, airflow, filters, thermostats, and drainage systems to identify faults, maintenance needs, or potential safety issues. The goal is to optimize performance, extend equipment life, prevent breakdowns, and maintain indoor comfort.
Performing an AC Inspection using eAuditor involves a comprehensive, step-by-step evaluation of an air conditioning system to ensure optimal functionality, safety, and efficiency. This process helps identify potential issues early, maintain system reliability, and extend equipment lifespan through detailed inspection, documentation, and corrective actions.

- Inspect the outdoor condenser unit for damage, corrosion, or debris accumulation.
- Clean or report dirty coils and fins obstructing airflow.
- Check refrigerant lines for insulation damage or visible leaks.
- Confirm secure mounting and vibration isolation pads are intact.
- Look for signs of oil stains indicating leaks.
-
Refrigerant System Assessment
- Measure refrigerant pressures and temperatures to verify correct charge.
- Detect leaks using electronic leak detectors, UV dye, or soap solution.
- Confirm refrigerant type complies with regulations and system specifications.
- Assess the condition of expansion valves and filters.
III. Electrical System Check
- Inspect wiring, connectors, and terminals for wear, corrosion, or looseness.
- Test capacitors, contactors, relays, and circuit breakers.
- Verify proper grounding and insulation resistance.
- Check for overheating signs or unusual odors.
- Airflow and Ventilation
- Measure airflow velocity and volume at supply and return vents.
- Inspect ductwork for leaks, disconnections, or blockages.
- Evaluate air filter condition; clean or replace as needed.
- Verify damper positions and balance of air distribution.
- Thermostat and Control Systems
- Check thermostat calibration and setpoint accuracy.
- Test all control functions, including timers, sensors, and remote access.
- Review programmable schedules for energy-saving modes.
- Inspect control panels for error codes or alarms.
- Drainage and Condensate Management
- Inspect condensate drain pans and lines for clogs or leaks.
- Confirm proper drainage to avoid water damage or mold growth.
- Check pumps (if applicable) for operational status.
VII. Operational Performance
- Observe system start-up and shutdown sequences.
- Measure temperature differential across the evaporator and condenser coils.
- Listen for abnormal noises such as rattling, grinding, or hissing.
- Check the compressor and fan motor amperage against specs.
- Assess vibration levels and mounting stability.
- Reporting and Follow-Up
- Comprehensive Inspection Report
- Document findings with notes, photos, and measurement data.
- Highlight critical issues needing immediate repair.
- Provide recommendations for preventive maintenance or upgrades.
- Classify defects by severity: critical, major, minor.
- Share reports with maintenance teams and management.
- Corrective Action Tracking
- Assign tasks via eAuditor with clear deadlines and responsible personnel.
- Monitor the progress of repairs or adjustments.
- Schedule follow-up inspections to confirm resolution.
- Log recurring issues for trend analysis.
III. Continuous Improvement
- Use collected data to identify patterns and root causes.
- Update inspection checklists as new technologies or standards arise.
- Conduct periodic staff training and refresher courses.
- Promote a proactive maintenance culture for extended equipment life.
- Integrate inspection data with facility management systems.
