Heat Pump Regassing in Johannesburg & Gauteng

Leak detection first, then correct-charge regassing by weight.

A heat pump is a sealed system: if it is short of gas, there is a leak. Simply topping up sends the same refrigerant back into the atmosphere within months and masks the fault. We pressure-test, trace the leak, repair it, evacuate to vacuum and then charge by weight to the manufacturer's plate data.
