Commercial Air-Conditioning Maintenance Checklist

Running a retail shop, warehouse, or multi-storey office in Queensland’s heat means your HVAC is mission-critical. A single breakdown can cost thousands in lost trade and emergency call-outs. Use our commercial air-conditioning maintenance checklist to:

  • Reduce surprise breakdowns by up to 40 %

  • Slash energy waste (clients see 10–15 % savings)

  • Keep documented proof for QBCC and NCC audits

Why a Structured Checklist Saves You Money

Pain point How a checklist helps
Unplanned downtime Scheduled inspections catch loose belts & clogged filters before they shut you down.
High power bills Correct refrigerant charge and cleaning coils can restore 15 % efficiency.
Compliance risk A signed logbook satisfies QBCC and NCC 2025 Section J obligations.

Monthly Tasks for Site Managers (DIY)

  • Verify thermostat set-points vs actual room temperature

  • Inspect filter access doors—ensure seals intact

  • Check for unusual vibration or noise after hours

  • Ensure return-air grilles are obstruction-free

  • Wipe controller screens and test fault indicators

Pro tip: Set a recurring calendar alert. Five minutes each month can prevent a five-hour breakdown.


Quarterly Tasks (Recommended by Acro Refrigeration)

  1. Replace or clean filters

  2. Tighten electrical terminals; record amperage draw

  3. Treat condensate drains with antibacterial tablets

  4. Inspect fan belts for glazing and tension

  5. Lubricate motor bearings (if non-sealed)

  6. Clean condenser coils with low-pressure water spray

  7. Check sight glass & measure superheat / sub-cool (refrigerant health)

Task Why it matters
Recalibrate thermostats and BMS sensors Mis-calibration of 1 °C can raise energy costs 5 %.
Pressure-clean evaporator coils Restores heat-transfer efficiency.
Conduct insulation resistance test on compressors Early detection of winding breakdown.
Replace fan belts & vibration mounts Prevents catastrophic bearing failure.
Review asset age & efficiency Budget for upgrades before R-22 phase-out deadlines.

How to Use This Checklist With Your Rooftop or Split Systems

  • Rooftop package units: focus on filter changes and condenser-coil cleaning—these units run hotter.

  • Large split systems (≥ 20 kW): ensure both indoor and outdoor coils are documented separately.

  • VRV/VRF systems: add refrigerant leak-detection log to your monthly tasks.
