It’s simple to glance at and put away the service report your air conditioning expert gives you. However, that report serves as a technical health check of your system and is more than simply a formality. You can avoid future unplanned repairs, excessive energy bills, or needless aircon servicing by being aware of what’s in the report and understanding what to look for.
Standard Items in an Aircon Servicing Report
A standard servicing report typically includes the system details (brand, model, capacity), inspection results, and technician remarks. At the minimum, you’ll see notes on:
- Filter condition
- Coil cleanliness
- Refrigerant levels
- Compressor function
- Drainage system checks
- Operational test outcomes
Each item tells a story about how your unit is running. Filters clogged with dust, for instance, not only reduce airflow but also force the system to overwork, resulting in higher energy use. If the report mentions “refrigerant low”, that’s not a minor footnote—it could be a sign of a leak that may soon escalate into a major fault.
Red Flags in the Report You Shouldn’t Ignore
Some remarks in a service report might sound harmless but signal bigger problems:
- “Unusual noise during operation” – This report can be a warning sign for loose parts or worn bearings in the blower or compressor. Left unchecked, it leads to costly repair.
- “Condensation around indoor unit” – Often overlooked, this report indicates poor drainage or insulation issues that can lead to water damage or mould growth.
- “Fluctuating temperature” – This report suggests a thermostat problem or failing sensors, meaning your unit isn’t cooling as efficiently as it should.
Technicians may use vague terms like “monitor” or “observe” to flag these. Don’t wait until the next visit—ask for clarification and discuss repair timelines immediately.
What a ‘Passed’ Report Doesn’t Always Mean
Just because the report says your system passed doesn’t mean everything is in perfect shape. Many servicing companies use tick-box forms where minor issues get overlooked unless they’re flagged specifically. For instance, coils might be partially blocked but not enough to fail a visual inspection. However, this still affects heat transfer and system efficiency.
Moreover, some reports might pass a unit while recommending deep cleaning or chemical wash “at the next service”. Treat this as a cue that your current service might have been just surface-level. Delaying deep cleaning could result in biofilm build-up, especially in humid environments.
The Difference Between a Good and a Lazy Report
A reliable servicing company will provide detailed comments, not just a series of checked boxes. Look out for notes explaining why something was done—or not done. For example: “Blower motor lubricated, no unusual vibration” shows proactive maintenance. On the other hand, reports that simply state “cleaned unit” with no reference to findings suggest a rushed or incomplete job.
Also, a good report should clearly list any recommendations, costs of potential aircon service repair, and urgency levels. If you’re only seeing vague comments like “needs monitoring”, press the technician for specifics or ask for photos before and after the service.
How to Use the Report to Your Advantage
Use your service report as a maintenance log. Compare it across past visits. Has the same issue been flagged repeatedly without being fixed? That’s a sign of either poor follow-up or a more serious underlying problem.
Additionally, some landlords and building managers require these reports for compliance or warranty purposes. Having clean, detailed service documentation helps in disputes, insurance claims, or resale negotiations.
Conclusion
Aircon servicing isn’t just about ticking off routine maintenance—it’s about staying informed on your unit’s condition. The service report is your window into the health of your system. Don’t treat it as paperwork. Scrutinise it, ask questions, and address issues early. Your future self—and your wallet—will thank you.
