Heat Pump Repairs in Randfontein
Heat Pump Repairs in Randfontein covers fault-finding and repair of air-source hot water and pool heat pumps. Mining and industrial sites with boiler plant and bulk hot water requirements.
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.
The installed base here is industrial, so most plant is three phase, duty-cycled hard and tied into process or steam distribution. Water quality testing is included with maintenance in this area.
West Rand visits carry a fuller van stock because parts runs back to Johannesburg cost time. Sites with long, poorly insulated pipework lose more heat in distribution than most owners expect, which reads as a capacity problem at the outlet. Peak draw-off matters more than total daily volume: plant that satisfies a whole day of demand can still fail at a 45-minute shower peak.
