Generator Service & Maintenance in Sandton, Planned Around Your Building
We service and maintain generators across Sandton: paralleled systems under the CBD towers and hotels, sets behind bank and head-office server rooms, and home standby sets in Morningside, Sandhurst and Hyde Park that stand for months and then carry a house through a long outage. Every visit is timed around the building and recorded.

Who needs it
Routine servicing in Sandton
Office towers and head offices: Commercial generator services
Landlord-owned systems serving many tenants, often two or more sets in parallel, where the lease sets out what the standby supply must do.
Hotels and conference venues
Sets that may carry kitchens, lifts and a full house at any hour; the test run is timed so guests never notice.
Server rooms and trading floors: Load bank testing
A set feeding a UPS must hold a steady frequency under rectifier load, so the service includes a run under load with the UPS watching.
Homes and cluster complexes: Residential generator services
Silent diesel and gas sets in Sandhurst, Hyde Park, Inanda and Morningside, and the shared sets at complex gates.
Servicing
What a generator service in Sandton includes
A Sandton service happens in a basement plant room or on a parking level more often than in a garden: booked through building management, often after hours, and taking in the day tank, the ducted radiator, the exhaust run and the changeover.
- Engine oil and filter, with the fuel, air and water-separator filters
- Coolant level and condition, radiator, hoses and belts
- Starting battery load-tested, charger output and terminals checked
- Fuel system checked for leaks, water and contamination, tank to injectors
- Alternator, AVR, output connections and earthing checked
- Controller settings, alarms and hour meter recorded
- Test run under load: voltage, frequency and temperatures
- Changeover (ATS) operation confirmed where fitted
You get a written record of what was done and found. The full list is in our service checklist; generator servicing explains the work and a maintenance plan keeps it on schedule.
Intervals
How often a Sandton generator needs a service
| The set | How it runs | What that means |
|---|---|---|
| Tower or hotel system through load shedding | How it runsTwo or three slots a day, for weeks at a time | What that meansHundreds of hours a quarter: the hours interval comes first |
| Server-room set with a UPS | How it runsStarts on every outage and runs lightly loaded | What that meansLight running risks wet stacking, so each service includes a run under proper load |
| Home standby set | How it runsRuns during outages and on its weekly test | What that meansThe time interval comes first; battery, fuel and changeover matter more than wear |
Our service intervals guide works out the next service from the hour meter; wet stacking explains why light running harms a diesel.
Plans
Maintenance plans for Sandton sites
Building and portfolio plans: Generator maintenance
For landlords and facilities managers: services and test runs by set, with reports that show tenants and insurers the supply was tested.
Critical-standby plans: Load bank testing
For server rooms, trading floors and hotels: a monthly run under load, battery and charger checks between services, and the UPS hand-over confirmed.
Body corporate and HOA plans: Residential generator services
For the shared set at a complex gate: one schedule, one quotation to the trustees, and a record the next trustees inherit.
Home plans: Generator servicing
For a house whose set seldom runs: a service before the season, test runs that prove the battery and changeover, and fuel checked for water.
Prevention
What a Sandton service catches before the outage does
Almost every repair we do in Sandton would have shown up at a service: a charger putting out the wrong voltage is found with a meter before it cooks the battery, water in a day tank is drained before it reaches the injectors, and a slow thermostat becomes a line on the report rather than a shutdown at two in the morning.
When something has already failed, our Sandton generator repairs page covers the faults we fix there most and what to send before we arrive. A plan keeps the test runs honest: a set started every week under load has had its battery, fuel and controller proven. We also service generators in neighbouring Bryanston, Rivonia and Rosebank, and across Sandton.

FAQ
Frequently asked questions
Can you service our Sandton building’s generators after hours?
Yes. We work 24/7, so services and the test run under load are booked outside business hours by arrangement with building management.
Our tower has three sets in parallel. Is that one service or three?
Three services and one system check: each set gets its own oil, filters, coolant, battery and fuel work, then synchronising and load sharing are tested with the sets running together.
How often should a home generator be serviced if it only runs during load shedding?
At least once a year, and sooner if the hour meter reaches the engine manual’s interval. Two slots a day for a month adds more than a hundred hours, so check the meter after a heavy month.
