Yes, we repair generators in Bordeaux, from house sets and medium standby units to the few light commercial sets near the Randburg business district, at the property. We are open 24/7 and arrive within 1 hour for breakdowns, and we diagnose before we quote in writing, so nothing is fitted on a guess.
Bordeaux is a compact residential suburb bordered by Blairgowrie and Ferndale, a few minutes from the Randburg business district. The machines here are house sets and medium standby units, plus a handful of light commercial sets, rather than workshop diesels that run a shift.
A starting fault in Bordeaux is usually a battery that can no longer turn a medium starter motor. Voltage faults show up only after the engine is running and the lights are still wrong. We keep those two jobs separate, so you are never sold a regulator for a battery fault.
Servicing pairs the oil and filters with a charger test, because a new battery fitted to a dead charger goes flat just as quickly as the old one.

Bordeaux faults start at the crank, then move to voltage once the engine is running.
A click or a slow crank on a medium set usually means the battery has lost capacity. We test it under cranking load.
If the battery is flat after every outage, the charger is the next thing we test.
Voltage that sags while the engine sounds normal points to the AVR or the alternator.
A light commercial set is tested with its own load connected, not a house load.
Only once the engine turns do we move to fuel, filters and air in the lines.
If engine speed falls under the load, we check the governor and fuel delivery.
Bordeaux’s handful of light commercial sets belong to small businesses a few minutes from the Randburg business district. They carry computers, lights and sometimes a fridge, and a voltage fault often appears only once that load connects. We repair them with the business load running, read any alarm on the panel first, and can book the visit before or after working hours.
We prove the Bordeaux battery before touching the controller. If the engine cranks and will not fire, we move to fuel. Call or WhatsApp and tell us what you hear when you try to start it.
Wrong voltage with a steady engine is the AVR or alternator, not the fuel. No output at all sends us to a breaker, the excitation or the wiring.
Where the set is automatic, a failed start signal is panel work and we test the changeover too. Manual medium sets go straight to the battery, fuel and output checks.
Filter changes and charger tests on a schedule belong to planned servicing. For Bordeaux homes and medium sets, that work and maintenance plans are on the Randburg servicing and maintenance page.
We service residential and medium standby sets across Bordeaux. Share the kVA from the data plate when you book.
ProService Generator Repairs services and repairs these brands, found on many Bordeaux home and medium standby sets.
House standby sets are serviced where they stand, with the charger tested alongside the battery.
Small business sets are tested with their own load, so the business keeps running.
Larger canopies go on a maintenance plan and are serviced on site.
We treat a click as a battery question before blaming the controller.
Output is metered once the engine runs, so the fix matches the reading.
We never fit a new battery to a charger that cannot keep it full.
Bordeaux is served by the same team as Ferndale and Blairgowrie.
