In brief
- Cooling faults in Qardho hide inside walls and ceilings, so they only show up as poor cooling after handover.
- A supervisor who signs without checking pipe sizing, insulation and pressure records lets faults stay hidden behind finishes.
- Agree the hold points, ask for the tests in writing, and walk the work before ceilings close.

Cooling installation supervision gaps in Qardho are the spaces in a build programme where nobody checks the work before it is covered up. When a supervisor signs off on progress without seeing pipe sizing, insulation joints or pressure test records, faults stay hidden until the rooms are hot and the question becomes who will open the ceiling to fix them.
How does weak supervision let cooling faults hide?
Cooling work fails quietly because most of it disappears behind plaster, ceilings and service voids. A supervisor who only attends the final switch-on sees a working unit on a hot afternoon and nothing else. The refrigerant charge may be short, the pipe may be undersized for the run, or the insulation may be split at a bend. Each fault reduces capacity before the system even reaches the room.
Supervision gaps usually come from three things: the supervisor is covering several sites, the inspection points were never written into the programme, or the trade is treated as a specialist extra rather than part of the build. Ask the project manager for the inspection and test plan. If it has no hold points for pipework, insulation and pressure testing, the gap is already there.
General practice is to test pipework before ceilings close and to record the result. Confirm the exact test pressure, duration and acceptance criteria with the project engineer and the unit manufacturer's instructions. Do not accept a verbal "tested" from a subcontractor.
What happens when an inspection is missed?
A missed inspection means finished work has to be opened again. Once ceilings are closed and finishes are complete, fixing a joint or re-routing a pipe means breaking out plaster, cutting into a ceiling and remaking the finish. The cooling performance may only drop slightly at first, then more as the season turns, so the defect surfaces long after the trade has left site.
The clearest warning sign is a handover pack that contains no pipe sizing calculation, no insulation specification and no pressure test record. Ask for them in writing. If the contractor says the records were not kept, that is the finding. Check what the contract says about as-built records and testing, and what it allows on payment, before you release anything.
How do you close the gap on a Qardho site?
Close the gap by naming the inspections before the work starts and putting them in the programme with dates. For cooling installation, that means pipe sizing against the approved drawing, insulation continuity at joints and bends, pressure testing before ceilings close, and a documented refrigerant charge.
Identify a comparable completed installation yourself, whether in Qardho or elsewhere, and record how the rooms perform at the hottest part of the day against what the design promised. Ask the relevant municipal office directly whether it holds records, borehole logs or inspection practice for the plot. Ask two suppliers for written equipment schedules so the installed unit can be compared with what was specified.
During installation, attend the pressure test. Watch the gauge, note the reading and the time, and keep the signed sheet. That one visit removes most of the space where a fault can hide.
What to do next
Before the next cooling package starts in Qardho, write the hold points into the programme: pipe sizing check, insulation check, pressure test witness and charge record. Send them to the contractor and ask for the test sheets in return. Then attend the first pressure test yourself and keep the signed record.
Frequently asked questions
Who should witness the pressure test on a cooling installation in Qardho?
The site supervisor or the client's representative should attend and sign the test sheet. If the contract names a third-party inspector, that person attends instead. Agree who signs before the pipework is installed.
What records should a client keep for a cooling installation?
Keep the approved pipe sizing drawing, the insulation specification, the signed pressure test sheet and the refrigerant charge record. Ask the contractor for them at handover and check what the contract requires.
