Aircon Gas Top-Up
Aircon gas top-up restores refrigerant that's been lost. We check pressure first to confirm low charge is actually the cause, because topping up a leaking system only buys time before the same problem returns. If the pressure won't hold, we'll tell you and recommend leak detection instead. For current rates, see the pricing page.

What Aircon Gas Top-Up Covers
Refrigerant top-up for R22, R410A, and R32 systems, after we pressure-check to confirm the cause of the loss. Common situations where a top-up fits:
Air blows but isn't cold
The unit runs, but there isn't enough refrigerant to transfer heat properly.
Ice forms on the indoor coil or piping
Low charge makes the evaporator overcool and freezes surface condensation.
Previous top-up lasted a few years
Slow loss is manageable after a pressure check. A recent repeat loss should be treated as a leak first.
When to Start Elsewhere
Top-up shouldn't be the default if the system's clearly losing gas or the fault points somewhere else.
Gas dropped again within months
Points to an active leak. Leak detection or pressure testing should come first.
System is completely empty
A leak or failed component has to be found before recharging, or the gas escapes again.
Gas pressure is normal
The cooling fault's elsewhere: airflow, compressor, expansion valve, sensor, or control issue.
What We Check Before Adding Gas
Top-up only happens after we've checked the system enough to know it makes sense.
Pressure check
Manifold gauges tell us whether refrigerant's low, how far it's dropped, and whether the pressure is holding.
Leak assessment
If pressure's low and not holding, we explain the leak risk before recommending any top-up.
Refrigerant type confirmed
R22, R410A, and R32 aren't interchangeable. We confirm the type from the unit nameplate before adding gas.
Top-up and verify
If pressure holds, we add the correct refrigerant amount, then run the unit to verify cooling performance.
What You Get
Restored cooling without hiding a leak.
Pressure checked before top-up
You know whether low gas is the actual cause, instead of paying for refrigerant blindly.
Right gas, right quantity
Refrigerant matched to the system type and measured before and after.
Leak risk explained
If pressure doesn't hold, you get the facts before deciding on leak detection or repair.
Not Sure What Failed?
If the fault is not confirmed yet, start with an on-site inspection before choosing a repair path.
