ATS and controller faults
If the set starts on the key but the building never transfers, we test the controller output and the changeover contactor before anyone opens the engine.

Standby Generators Around Rosebank, Parktown and Houghton
Yes, we repair generators across Johannesburg North, from automatic standby sets on large Houghton and Westcliff stands to shared apartment-block sets in Killarney and office generators in Rosebank and Parktown. We are open 24/7 and arrive within 1 hour for breakdowns; the technician diagnoses the fault and quotes it in writing before starting. ProService Generator Repairs has worked on diesel, petrol and gas generators since 2000 and covers Rosebank, Parktown, Houghton, Parkhurst, Melrose, Killarney and Norwood. Call or WhatsApp 082 057 4605 to report a fault.
Property here shapes the visit. Houghton and Westcliff homes sit on large, often steep stands, with the generator tucked beside a pool pump room or at the end of a long driveway. Killarney and Riviera have older apartment blocks that share one set for the whole building, where the body corporate wants a record of each service. Rosebank and Parktown add offices and shops along Oxford Road and Jan Smuts Avenue, many with basement plant rooms and three-phase standby sets.
Most of these generators are automatic. They wait for weeks, then have to start, transfer and carry the load with nobody touching them. Our northern-suburbs visits therefore focus on the battery and charger, the AMF controller and the changeover, and we finish with a mains-failure test wherever the site allows it.
Sandton lies to the north-east and Randburg to the north-west. Both are part of our Johannesburg coverage, each with its own page, with the same team, prices and 1-year workmanship guarantee.

Common Generator Problems We Diagnose
In the northern suburbs, most faults sit in the automatic system around the engine rather than in the engine itself.
AVR and voltage faults
Dimming lights or equipment that drops out under load point to regulation, wiring or the alternator. We measure output with the load connected and adjust only what the readings show.
Battery and start faults
A complex set that clicks and stops usually has a battery the charger stopped topping up, or corroded terminals. We test all three.
Sets that missed a service
Old oil, loaded filters and tired coolant show up on the first automatic start after a long wait. We service the set and run it so any deeper fault shows before we leave.
Generators We Service
We service diesel canopy sets, petrol portables and gas generators across the northern suburbs, from a small set in a Parkhurst garden to a three-phase unit in a Parktown office basement.

Frequently Asked Questions
Do you work on generators in Rosebank, Parktown and Houghton?
Yes. We repair and service generators on site in Rosebank, Parktown, Houghton and every other Johannesburg North suburb, from Greenside and Saxonwold to Norwood and Waverley.
Can you repair the shared generator in our Killarney apartment block?
Yes. We work with the body corporate or managing agent to arrange access, repair the set where it stands and leave a record of what we checked and replaced.
Our Rosebank office generator runs, but the building stays dark. What is wrong?
A running set with a dark building usually points to the ATS or the controller, not the engine. We test the start signal, the changeover contactor and the output breaker to find where the power stops.
Can you test whether our automatic generator will take over in an outage?
Yes. Where the site allows, we switch off the mains input and watch the set start, transfer and carry the load, then restore the supply and check that it hands back cleanly.
Why does our standby generator battery keep going flat?
The battery may be at the end of its life, or the charger may have stopped working. We test the battery, the terminals and the charger together so the new battery does not go flat too.
Do you also cover Sandton and Randburg?
Yes. Both border Johannesburg North and are part of our Johannesburg coverage, each with its own page, with the same team, callout rates and guarantee.
