Introduction
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)
- Replace or clean filters
- Tighten electrical terminals; record amperage draw
- Treat condensate drains with antibacterial tablets
- Inspect fan belts for glazing and tension
- Lubricate motor bearings (if non-sealed)
- Clean condenser coils with low-pressure water spray
- Check sight glass & measure superheat / sub-cool (refrigerant health)

Annual Deep-Service Items
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.
