Techsun Heat Pump Repairs in Randfontein
Techsun heat pump repairs in Randfontein. 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.
Heat pump repairs cover the refrigeration circuit, the electrical control side and the water side of the unit. Most call-outs we attend start as 'no hot water', but the underlying fault is usually a failed capacitor, a blocked evaporator, a defrost sensor out of tolerance, or a slow refrigerant loss that only shows up under load.
Mining and industrial sites with boiler plant and bulk hot water requirements. Water quality testing is included with maintenance in this 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.
