Large generators
We work on small, commercial and industrial generators
A portable petrol set, a home standby generator, a commercial diesel and a larger industrial set are all booked as generator work. Capacity is read from the data plate. A maximum kVA is not published here.
Diesel generator work
Diesel generator repairs and servicing
Diesel visits cover no-start diagnosis, fuel delivery, batteries, overheating, oil and coolant leaks, alternator output and controller alarms. Injectors and fuel pumps are opened only after filters and air in the lines have been checked.
Planned generator servicing and generator maintenance sit alongside the repair. Fuel-system detail is on fuel system repairs.
Petrol and portable generators
Petrol generator repairs and servicing
Smaller portable and home petrol generators are repaired and serviced as well. Typical work is a set that will not start, runs poorly, or runs and produces no useful power. Petrol does not replace the diesel and commercial work above.
Business sites
Commercial and industrial generator services
Offices, retail sites, warehouses, commercial properties and industrial facilities use the same onsite visit: repairs, servicing, maintenance and fault diagnosis. Load testing, controller work, ATS faults and installation are booked when that is the job. A client list is not published, and a site is not claimed unless the visit is the one in front of the technician.
Faults
Common generator problems we diagnose
Each symptom has its own page. The broader visit, before a part is named, is generator fault finding.
Components
Generator electrical, engine and controller repairs
A generator fault can sit in the controller, the ATS, the AVR, the alternator, the starter, the battery and charger, the fuel system or the radiator. The pages below are the usual next step once the symptom is known. Fuel pumps, injectors and solenoids stay inside the fuel-system visit unless that part is already identified.
- Generator controllers
- ATS repairs
- AVR repairs
- Alternator repairs
- Starter motor repairs
- Battery charging systems
- Fuel system repairs
- Cooling system repairs
Generator controllers
Supported controller work includes SmartGen, Deep Sea Electronics (DSE), Datakom and Generac modules: diagnosis, replacement, configuration and alarm investigation, including AMF and ATS behaviour where that is part of the set. Not every model can be repaired or reprogrammed. See generator controllers and generator controller repairs.
Brands
Generator brands we repair and service
ProService Generator Repairs works across these makes rather than as a single-manufacturer site. Diesel, petrol and gas stay on separate routes. The full list is on the brands page.

Questions
Straight answers before you book
Wondering what a repair costs? Our pricing guide breaks down what to expect before a technician arrives. For how a visit is booked, see generator callouts, or read how our generator specialists work.
What generator sizes do you repair?
Portable petrol sets, residential standby generators, commercial diesel sets and larger industrial generators. Capacity is read from the data plate on site. A maximum kVA is not published.
Do you repair diesel and petrol generators?
Yes. Diesel and petrol generators are both repaired and serviced. Gas and dual-fuel sets are booked on their own pages when that is the fuel on site.
Which areas in Gauteng do you cover?
Callouts are arranged across Johannesburg, Pretoria, Sandton, Centurion, Midrand, the East Rand, Randburg, the West Rand and the Vaal. Suburb pages sit under those regions.
How often should a generator be serviced?
Follow the manufacturer schedule. Standby sets are often serviced at least once a year, or sooner when running hours are high. The servicing and service-interval pages explain how that is decided.
What information should I send before a callout?
The suburb, the make and model if you have them, the kVA, the fuel type, and what the generator is doing. A photo of the data plate or the controller alarm is useful.
Can you diagnose a generator that will not start?
Yes. No crank, a click, and an engine that turns but will not fire are different jobs. The cause is tested before parts are recommended.
Do you work on generator controllers?
Yes, on supported modules including SmartGen, Deep Sea, Datakom and Generac. Not every controller can be repaired or reprogrammed. The controller page explains the scope.
Do you service commercial generators?
Yes. Offices, retail, warehouses and other business sites are serviced and repaired on site, including standby sets that must start when the supply drops.
