Generator sites we repair across Randburg
Shops and offices in Ferndale and the CBD: Commercial generator services
Ferndale mixes houses with offices and shops along Bram Fischer Drive; the sets stand in back yards behind the tills.
Warehouses in Strijdom Park: Industrial generator services
Three-phase sets between the N1 and Malibongwe Drive, carrying compressors, cold stores and loading bays.
Townhouse complexes and blocks of flats: Residential generator services
Many complexes and blocks have a shared set for the gate, lifts and passage lights, booked by the body corporate.
Older houses from Blairgowrie to Boskruin: Standby generators
Silent diesel and petrol sets, often early installations with the changeover in the garage.
Corporate offices, schools and medical rooms: Voltage problems
Head offices such as MultiChoice’s, school sets carrying office, kitchens and security, and consulting rooms whose fridges need steady voltage.
Repairs
Generator faults we fix in Randburg
Generator won’t start: Generator not starting
Flat batteries, failed chargers, stale fuel and starter faults, fixed on site.
Battery and charging faults: Battery not charging
Chargers, charge alternators and batteries that cannot crank the set when the mains fails.
Fuel and injector faults: Fuel system repairs
Contaminated diesel, blocked filters, air in the lines, lift pumps and injectors.
AVR and voltage faults: Voltage problems
Low, high or swinging voltage from the AVR, exciter or rotating diodes.
ATS and changeover problems
The set runs but the building stays dark, or the load never returns to the mains.
Overheating
Shutdowns from blocked radiators, failed fans, thermostats and coolant leaks.
Strijdom Park
Three-phase sets, motor loads and drum fuel
Strijdom Park’s warehouses load a generator the way no shop does: a compressor started direct-on-line draws several times its running current, and single-phase loads crowded onto one phase leave it hot with uneven voltage. A set that trips as the biggest motor starts is often short of kVA.
Fuel is the other local fault: drum diesel collects water and dirt, and yard dust packs the air filter and radiator. We sample the tank before touching the injectors; the kVA sizing guide and single versus three phase explain the arithmetic.
- Motor starting current checked against the set’s kVA
- Phases balanced where single-phase loads crowd one leg
- Drum fuel sampled, filters and radiator cleared
Response
On site in Randburg in 1–2 hours
Technicians on site in 1–2 hours, 24/7. Malibongwe Drive, Bram Fischer Drive and Republic Road are the main routes and the N1 Western Bypass passes Strijdom Park, so a technician comes off any of them. Say where the set stands and who signs contractors in.
While you wait, stick to what is safe: the fuel gauge, main breaker, emergency stop and controller screen. Press start twice at most and leave the changeover panel closed. WhatsApp a photo of the controller, nameplate and hour meter so the likely parts travel with us; emergency generator repair covers after-hours calls.
Every make
Makes we repair in Randburg, portables to warehouse sets
We Service & Repair All Generator Brands. In Randburg that runs from the petrol and inverter portables kept in flats, Ryobi and Honda-engined units among them, through silent diesel sets from Kipor, Bundu Power, Pramac, SDMO and Mac Afric behind shops and at complex gates, to the Strijdom Park canopies built around Perkins, Cummins, Deutz or John Deere engines with Stamford or Leroy-Somer alternators and Deep Sea Electronics, ComAp or SmartGen controllers. See our brand pages and portable generators.
Prevention
Why a Randburg set fails twice
The second call comes when only the symptom was treated: a fresh battery under a charger that still drifts, a warehouse set restarted with the water still in the drum, a side-passage set that overheats again because nobody cleared the radiator. We fix the fault and report what else we saw.
Servicing breaks the cycle: our Randburg generator service and maintenance page sets out what a service behind a shop, in a Strijdom Park yard or at a complex gate includes, and our plans for landlords, factory managers and body corporates. Generator repairs explains how we find a fault; we also attend breakdowns in Bryanston, Rosebank and across Randburg.

FAQ
Frequently asked questions
Can you repair the generator at our Ferndale shop while we trade?
Usually. Diagnosis and most repairs happen with the shop on mains; anything that moves the tills onto the generator is booked outside trading hours.
Our Strijdom Park set trips every time the compressor starts. Is it broken?
Often it is undersized rather than faulty: a direct-on-line motor draws several times its running current to start. We measure the loads, check the phase balance and governor, and say whether the set copes; see shutting down or tripping.
Our complex’s generator powers the gate and lifts. Who do you deal with?
The body corporate, through a trustee or the managing agent. We quote whoever the trustees name, repair on their instruction and write the report for the minutes.
Do I pay for the callout if the set is not worth repairing?
Free callouts and quotations. Work starts once you accept the quotation, and when an engine or alternator is past saving we say so; our repair or replace guide explains how we weigh it.
