Commercial Heat Pump Regassing in Johannesburg & Gauteng
Leak repair and charge correction on multi-unit commercial plant.
On commercial banks, one under-charged unit drags the whole system because the controller keeps calling for heat while a module runs at poor efficiency. Charge correction across a bank starts with identifying which module is losing gas and why — usually vibration fatigue at a joint or corrosion at the coil.
