Heat Pump Regassing in Centurion Highveld
Heat Pump Regassing in Centurion Highveld covers leak detection first, then correct-charge regassing by weight. Office parks and data-adjacent facilities with plantroom hot water systems.
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 is weighted towards hospitality, healthcare and office plant, which means longer daily run hours and larger storage volumes. Plantroom access and after-hours work coordinated with facilities teams.
Midrand and Centurion sit between the Johannesburg and Pretoria routes, so attendance windows are usually the shortest of any area. 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.
