Illustrative example, not a customer case: an office AC runs throughout the afternoon while the room remains uncomfortable. Someone suggests a refrigerant top-up. Before approving it, ask what evidence supports that diagnosis and what else has been checked.
Choose an explained diagnosis, an approved remedy and a recorded result. That sequence is more useful than an unexplained refrigerant top-up.
Describe the symptom before approving the remedy
Record when the problem began and whether it followed relocation or servicing. Note whether it occurs all day or mainly in the afternoon, and whether occupancy or room use changed. This history helps direct the inspection.
Distinguish weak airflow from air that moves normally but does not provide sufficient cooling. Both may be described as poor cooling, but they should not be treated as an identical complaint.
Ask for a connected diagnosis
DOE guidance considers airflow and refrigerant charge when evaluating AC performance. Ask for the relevant inspection findings and measurements, with an explanation of how they support the proposed work. A single pressure reading is not a complete diagnosis.
Charging should follow the equipment requirements. If a shortage is confirmed, discuss its cause, leak investigation where appropriate and the repair scope. Repeated top-ups do not demonstrate that the underlying issue has been resolved.
Make the service visit reviewable
Request diagnosis of the cooling complaint before authorising parts or refrigerant. Keep the findings and the post-repair operating record so a later technician can understand what changed.
| Proposed action | Question to ask |
|---|---|
| Add refrigerant | What confirms a shortage and explains it? |
| Clean the unit | Which components need cleaning? |
| Replace the equipment | What assessment supports replacement? |
| Close the job | How was the original complaint checked? |
Know the customer's role
Your role is to communicate the complaint and approve a defined scope. Refrigerant handling and electrical testing belong to a qualified technician. Avoid treating online readings or a neighbour's equipment as a specification for your own unit.

When should you compare repair with replacement?
If the report recommends a substantial repair, request a written option describing the fault, part, labour and intended result. Compare that with an appropriate replacement assessed for the space. Equipment age or the advertised supply price of a new unit alone does not provide a complete comparison.
| Option | Information to compare |
|---|---|
| Repair | Fault, part, labour, testing and any unresolved issues |
| Replacement | Model, supply, installation and any required route alterations |
| Site arrangements | Expected completion, service interruption and written warranty terms |
Confirm part availability and expected delivery when office operations depend on the decision. If an energy-saving estimate is offered, ask for its assumptions and comparison conditions instead of applying a generic percentage to your equipment. Begin with the inspection findings, then compare the complete cost and the actual operating needs of the site.
Questions & acceptance checklist
- Record the model and symptom timing.
- Mention recent work or changes in room use.
- Request findings before approving repairs.
- Keep the operating test and service report.
Before you decide
Does poor cooling always mean low refrigerant?
No. Airflow, operating conditions and equipment condition also require assessment before a charge-related conclusion.
What if refrigerant has already been added repeatedly?
Request an explanation for the recurrence and the investigation performed before approving another top-up.
What should I send when booking?
Send the model, location, symptom timing, any noise or water leakage and a description of recent servicing or relocation.
