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.
