What is a split system service checklist?
A split system service checklist is a structured maintenance form used to inspect and service split system air conditioning units. MapTrack helps HVAC technicians digitise split system servicing so every unit has a complete service history linked to the asset record. The checklist covers the indoor unit (filters evaporator coil blower drainage and electrical) and the outdoor unit (condenser coil compressor fan and refrigerant circuit).
Split systems are the most common form of air conditioning in Australian commercial and residential buildings. Regular servicing keeps them running efficiently prevents mould and bacteria growth in the indoor coil and drainage system and extends the lifespan of the compressor.
Benefits
- Consistent process: every split system receives the same thorough service regardless of brand model or technician
- Health and hygiene: cleaning the indoor coil and drain pan prevents mould and bacteria recirculation into occupied spaces
- Energy efficiency: clean filters and coils reduce head pressure and compressor energy consumption by up to 20 percent
- Warranty compliance: most manufacturers require documented annual or bi-annual servicing to maintain warranty coverage
- Early fault detection: checking refrigerant pressures and electrical readings catches developing faults before compressor failure
- Compliance documentation: signed service records demonstrate the PCBU has met their duty of care under the WHS Act

What to include in a split system service checklist
- Indoor unit filters: remove wash dry and refit filters or replace disposable filters
- Evaporator coil: inspect for fouling and mould then clean with approved coil cleaner if required
- Condensate drain: flush the drain pan and drain line to confirm free flow and no blockage
- Indoor fan and blower: check blower wheel for dirt buildup and verify correct fan speed operation
- Outdoor condenser coil: inspect for fouling and debris then clean with low-pressure water from inside out
- Compressor and refrigerant: record suction and discharge pressures and compare to manufacturer charge chart
- Electrical: check capacitor condition contactor condition wiring tightness and measure running amps
- Remote and controls: test all modes (cool heat fan dry auto) verify thermostat accuracy and check timer functions
How to complete a split system service
- Isolate the system: turn off the split system at the isolator switch and allow the unit to stop completely before beginning work
- Service the indoor unit: remove and wash filters inspect the evaporator coil for mould or fouling and clean with coil cleaner if needed
- Flush the drainage: pour water into the drain pan to confirm flow through the drain line and clear any blockage with a wet-dry vacuum or nitrogen
- Inspect the indoor blower: remove the blower cover and check the blower wheel for dirt buildup and the motor for unusual noise
- Service the outdoor unit: remove the condenser guard and clean the condenser coil with low-pressure water then check the fan blade and motor
- Check the refrigerant circuit: connect gauges and record suction and discharge pressures then calculate superheat and subcooling and compare to manufacturer specifications
- Document and close out: record all readings complete the checklist sign off and attach the service label to the indoor unit with the next service due date
How often should a split system be serviced?
Split systems should be serviced at least annually. In commercial environments with higher operating hours or dusty conditions bi-annual servicing (every six months) is recommended. Filters should be cleaned by the building occupant or cleaner monthly between professional services.
The Australian WHS Act requires a PCBU to maintain plant so it remains safe. While there is no prescriptive servicing frequency for split systems in legislation most manufacturers require at least annual servicing to maintain warranty.
Frequently asked questions
- What does a split system service include?
- A split system service covers indoor filter cleaning or replacement, evaporator coil inspection and cleaning, condensate drain flushing, blower wheel check, outdoor condenser coil cleaning, refrigerant pressure check, electrical component inspection, and remote controller function testing. It takes approximately 45 minutes to 1.5 hours per unit.
- How often should split system filters be cleaned?
- Filters should be cleaned by the building occupant or cleaner every month. Professional servicing including coil cleaning, refrigerant checks and electrical inspection should be performed annually or bi-annually depending on the operating environment and manufacturer requirements.
- Can I service a split system myself or do I need a licensed technician?
- You can clean filters and the indoor unit yourself. However, any work involving the refrigerant circuit, electrical components or condenser coil requires a qualified HVAC technician. Refrigerant handling specifically requires an ARCTick licence in Australia.
- Is the template free to use without MapTrack?
