Generator Repairs, Servicing & Maintenance FAQs

ProService Generator Repairs repairs starting faults, fuel faults, cooling shutdowns, controller alarms, transfer problems and sets that run but produce no power. Diesel, petrol and supported gas machines are booked as separate visits. The symptom decides which tests come first.

Yes. All generator repairs and engine overhauls are carried out on site at your premises. Diagnosis and servicing happen at the generator too, anywhere in Gauteng, so the set never has to be transported.

Yes. Diesel standby and commercial sets, and petrol portable and home sets, are both repaired. The fuel changes the tests. Diesel work is on the diesel generator repairs page. Petrol work is on the petrol generator repairs page.

Yes. We carry out generator engine overhauls and major mechanical repairs on site, on residential, commercial and industrial generators. An overhaul is quoted in writing after the engine has been inspected.

Yes. We issue and sign the electrical Certificate of Compliance (CoC) for the changeover switch installations we carry out. See generator installation for how a changeover switch is fitted.

A service covers the items that machine needs. Often that is oil, filters, coolant, the battery, belts where fitted, a fuel-system look and a controller check. Not every generator uses every part. The set is run afterwards and anything that should be watched is written down.

Most standby generators should be serviced once a year or at the manufacturer’s hour interval, whichever comes first. Published examples include 200 hours or 2 years on Generac home standby sets, and oil every 100 hours or 6 months on Honda portables after the first 20 hours. Sets that ran long hours during load shedding need servicing sooner. Our service interval guide lists the sources.

Yes. Maintenance contracts and service level agreements (SLAs) are customised for each client. We inspect and assess the generator, its condition, capacity and usage, and your requirements, then quote the plan in writing. There are no fixed packages or prices. Agreements are in writing and either party can cancel with 30 days’ notice.

A generator may not start because of the battery, fuel, a low-oil shutdown, an emergency stop or a controller that is not issuing a start. A silent set and a set that cranks are different jobs. See generator not starting.

If the engine is running and there is still no power, the fault is usually electrical: a breaker, the AVR, excitation, wiring or the alternator. Output is measured before the alternator is condemned. See generator not producing power.

Across Gauteng, 24 hours a day. We arrive within 1 hour for breakdowns. The main areas are Johannesburg, Pretoria, Sandton, Centurion, Midrand, the East Rand, Randburg, Roodepoort, the West Rand and the Vaal, with suburb pages under each region.

Your suburb, the brand, diesel or petrol or gas, the kVA if you know it, and what happens when start is pressed. Unknown fields can be left blank. Call or WhatsApp 082 057 4605, or use the contact form.

Workmanship is warranted for 1 year from completion, as set out in the terms. A fault directly related to the work is inspected again in that period. Parts follow the supplier warranty where one applies. Misuse, unrelated faults and wear are not covered.

It depends on the fault. Starting faults typically cost R600 to R3,500, AVR replacement R2,200 to R9,000 and control panel repair or reprogramming R3,500 to R14,000. You get a free written quote before any work starts, and our cost guide lists every range.

R400 to R700 in business hours and R700 to R1,400 after hours. The callout fee is only payable if you do not accept the quotation. If you accept the quotation, the callout fee is waived.

A basic service (inspection and fluids) typically costs R900 to R1,800, and an oil and filter change R600 to R1,400. The size of the generator and the parts it takes set the final figure, which is in the written quote.

An engine overhaul typically costs R9,000 to R28,000+, depending on the engine and what the inspection finds. We carry out generator engine overhauls and major mechanical repairs on site, on residential, commercial and industrial generators.

There is no fixed price. Maintenance contracts and service level agreements (SLAs) are customised for each client. We inspect and assess the generator, its condition, capacity and usage, and your requirements, then quote the plan in writing. There are no fixed packages or prices.

Yes. The written quote is free. A written quote is given before work starts and is valid for 14 days. If more work is found once the job is under way, it is explained and not done without your approval.
