Proper Gas Top-Up — Only After Confirming the Root Cause

What Was Happening
Customer reported:
System not cooling properly
Hadn’t done any gas check or servicing in years
No visible leaks, but performance had dropped gradually
They requested a proper check before topping up.
What We Found
Gas pressure was significantly below optimal range
No signs of visible leakage, but aging pipework insulation suggested slow degradation over time
Compressor startup was normal
Coil condition and airflow were intact
We confirmed that this was a true undercharge, not a guess.
What We Did
Performed a controlled gas top-up using proper manifold and R32 tank
Balanced pressure to manufacturer specs
Rechecked for system response and cooling output post-fill
Inspected pipework and advised on future insulation rewrap to prevent future loss
The Result
Cooling performance restored immediately
Pressure readings stabilised
No guesswork — top-up only done because readings and response confirmed the need
What Could’ve Gone Wrong
Running on low refrigerant long-term could strain the compressor
System would continue to overcompensate, driving up power use
Condensation could form on exposed lines, leading to corrosion or leakage
Misdiagnosis risk: customer might keep topping up without solving the cause
What This Case Shows
We don’t top up unless the numbers say so.
Too many customers are sold gas when it’s not the issue.
