Techsun Heat Pump Repairs in Modderfontein
Techsun heat pump repairs in Modderfontein. 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.
Redeveloped industrial estate with a mix of legacy plant and new residential developments. Legacy steam and new heat pump plant both supported. Gauteng municipal water is moderately hard, so scale on elements and heat exchangers is the single most common cause of falling performance.
