Techsun Heat Pump Regassing in Wierda Valley

Techsun heat pump regassing in Wierda Valley. Common on guest house and complex installations; scale management extends compressor life.

Techsun equipment we work on includes commercial hot water heat pumps. Commonly replaced parts on this brand are heat exchangers, controllers, and we keep or source these against the unit's model and serial plate rather than by guesswork.

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.

Wierda Valley is a high-value residential pocket of Sandton, typically with multiple geysers or a heat pump on buffer storage, and in many cases pool or underfloor heating on the same plantroom. Wierda Valley falls inside our core northern-suburb route, so response is normally same-day for loss-of-hot-water call-outs. Where a site runs on borehole water, hardness and iron content shorten service intervals considerably and are worth testing before setting a maintenance plan.
