Yes, we repair generators in Johannesburg West, from canopy diesels and petrol portables behind Melville and Westdene homes to the factory diesels in Industria, on site. We are open 24/7 and arrive within 1 hour for breakdowns; the fault is found and explained first, then quoted in writing. Since 2000, ProService Generator Repairs has worked on diesel, petrol and gas generators, and we cover Melville, Auckland Park, Westdene, Brixton, Sophiatown, Westbury and the Industria workshops. Call or WhatsApp 082 057 4605 to book.
The west splits neatly in two. Melville, Westdene and Auckland Park are older suburbs of houses on sloping stands, student digs and the cafés along 7th Street, where the generator is usually a canopy diesel or a petrol portable at the back of the property. Industria, Industria West and Langlaagte, off Main Reef Road, are factories and workshops with open-frame diesels that run through production.
Workshop sets here often show fuel trouble: filters loaded with dirty diesel, air in a line that was opened, or a lift pump that cannot keep up once the engine works hard. House sets more often have a starting-circuit fault or a missed service. When a generator runs but the output is wrong, we test the alternator and its connections separately from the fuel system, so you pay for one repair instead of two.
Roodepoort, with Florida and Constantia Kloof, is part of our Johannesburg coverage with its own page, and Krugersdorp belongs to our West Rand coverage, all served by the same team at the same prices.

What happens next
Charlie, lead technician: Degree in Mechanical Engineering, Degree in Electrical Engineering, Diesel Plant Fitter. Generator specialists since 2000.
West Johannesburg work splits between household standby sets and generators that earn their keep in a workshop. Each gets its own set of checks.
We confirm a restricted filter or an air leak with a fuel-side test, rather than assuming it from hard starting alone.
When the engine will not turn, we test the battery, cables and starter motor, then the shutdown circuit on the controller.
If engine speed is steady and the voltage is missing, we test the alternator windings, the excitation and the output protection.
Sets that run hard still miss services. A service visit shows which symptoms are wear and which are a fault that needs a quote.
We service homes, shops and workshop diesels across the western suburbs: single-phase and three-phase, petrol, diesel and gas.
ProService Generator Repairs services and repairs these brands, found on everything from Melville house sets to Industria workshop diesels.
We service house sets where they stand, test the battery and replace filters, so the set starts first time at the next outage.
Yard and workshop generators are serviced on running hours and tested under the load your machines put on them.
Bigger sets in the industrial pockets are repaired and maintained on site, with load bank testing when you need proof of capacity.
The same technicians look after a Melville house set and an Industria production diesel.
We test fuel delivery and the alternator as separate systems, so the quote covers the real fault.
If your address is in Roodepoort or Florida, our West Rand coverage brings the same team, prices and guarantee.
