Heat Pump Regassing in Modderfontein
Heat Pump Regassing in Modderfontein covers leak detection first, then correct-charge regassing by weight. Redeveloped industrial estate with a mix of legacy plant and new residential developments.
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.
The installed base here spans domestic geysers through to commercial plantrooms, so the first step is establishing exactly what is installed before quoting. Legacy steam and new heat pump plant both supported.
Ekurhuleni call-outs are grouped by area so industrial and commercial visits can be attended on the same run. Where a site runs on borehole water, hardness and iron content shorten service intervals considerably and are worth testing before setting a maintenance plan. Control scheduling is often the cheapest available improvement, particularly where heating windows overlap with peak tariff periods.
