Sirac Heat Pump Repairs in Randfontein
Sirac heat pump repairs in Randfontein. Modular banks where lead/lag sequencing faults are frequently mistaken for capacity shortfall.
Sirac equipment we work on includes commercial modular heat pumps. Commonly replaced parts on this brand are controllers, contactors, sensors, 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. Sites with long, poorly insulated pipework lose more heat in distribution than most owners expect, which reads as a capacity problem at the outlet.

What does Sirac heat pump repairs include?
Compressor, capacitor and contactor testing and replacement, Fan motor, blade and bearing replacement, Refrigerant leak detection, repair and recharge (R410A, R32, R134a), plus verification that the unit performs to the manufacturer's stated figures after the repair.
Do you service Sirac units in Randfontein?
Yes. Randfontein is inside our service area. West Rand visits carry a fuller van stock because parts runs back to Johannesburg cost time.
Is it worth repairing an older Sirac unit?
We give a repair-versus-replace figure with the quotation so the decision is based on cost, not on guesswork. Modular banks where lead/lag sequencing faults are frequently mistaken for capacity shortfall.
