We service and maintain every kind of generator Parktown and Houghton runs: Killarney block sets that must bring lifts and pumps back every outage, standby sets at the medical suites, offices and campuses, and home sets on Houghton’s big stands that run a few times a year, each visit written up.

Who needs it
Routine servicing in Parktown and Houghton
Apartment blocks in Killarney: Residential generator services
One set carries a whole block’s lifts and pumps every outage; serviced and tested so the trustees know the lifts return.
Medical suites and day clinics: Commercial generator services
Rooms around the Parktown medical precinct whose fridges ride on the set; the loaded run is booked outside consulting hours.
Offices and campus buildings: Load bank testing
Head-office and campus sets feeding a UPS, where drifting frequency shows as a UPS that refuses to leave battery.
Homes on big stands: Generator servicing
Silent diesel and gas sets in Houghton Estate, Lower Houghton, Westcliff and Saxonwold that stand for months between outages.
Servicing
What a generator service in Parktown and Houghton includes
A service here is as much about access as oil: a Killarney plant room opened by the caretaker, a suite that cannot lose its fridges in consulting hours, a Houghton home where someone must be in. Standing fuel and sulphated batteries get extra attention.
- 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
When a Parktown or Houghton generator is due
| The set | How it runs here | When the next service falls due |
|---|---|---|
| Killarney block set | How it runs hereEvery outage, under lifts, pumps and lighting | When the next service falls dueBy hours in a heavy quarter, yearly otherwise |
| Medical suite or clinic set | How it runs hereEvery consulting-hours slot, lightly loaded | When the next service falls dueYearly, with a run under proper load |
| Office or campus set with a UPS | How it runs hereEvery office-hours outage, lightly loaded after five | When the next service falls dueBy hours in a bad month, frequency and voltage logged |
| Home set on a Houghton stand | How it runs hereIdle for months, then a long evening under the whole house | When the next service falls dueYearly: battery plates, diesel and contactor deteriorate unused |
Our service intervals guide dates the next visit from the hour meter; diesel fuel contamination explains what a year in a tank does.
Plans
Maintenance plans for Parktown and Houghton
Body corporate plans: Residential generator services
For Killarney blocks: the trustees approve one annual schedule, test runs are logged under lift and pump load, and the file stays with the building.
Practice and clinic plans: Generator maintenance
For medical suites: services before opening, the changeover tested with the fridges on the set, and a report for the practice manager.
Office and campus plans: Load bank testing
For facilities managers: a quarterly run under the building’s load, the UPS watched as the set takes over, chargers metered in between.
Home plans: Generator servicing
For a Houghton or Westcliff house: a yearly visit before the storms, monthly starts the owner can watch, and the diesel tested rather than trusted.
Prevention
What a service here catches first
Few breakdowns in these suburbs arrive unannounced. A block battery that will not crank was overcharged for months; a Houghton tank that stalls the engine has carried water since the last storm; a contactor that leaves a suite dark was slow on the previous test. A service reads those signs while there is still time.
Once a set has stopped, our Parktown and Houghton generator repairs page takes over. The plans above also run in Rosebank, Auckland Park and Melville and the Johannesburg CBD, and across Johannesburg.
- Charger output checked against the battery
- Water drawn off the bottom of the tank
- Contactors timed on a live-mains transfer

FAQ
Frequently asked questions
Can you service our Killarney block’s generator without stopping the lifts?
Yes. The engine work needs the set stopped, not the building, so the block stays on mains. The lifts ride on the generator only for the transfer test, at an hour the caretaker picks.
Our suite cannot lose its vaccine fridge. When do you test the generator?
Before the first patient or after the last, and only for the minutes the transfer takes, with the voltage watched throughout. We work 24/7.
Our Houghton set runs a few hours a year. What is there to service?
More than the oil. A standing set sulphates its battery, collects water in the tank and lets the changeover seize, and the hour meter shows none of it; the yearly visit tests all three.
Why does our office generator smoke after a night carrying only the server room?
Because it ran cold. Under a small load a diesel never reaches working temperature, and unburnt fuel coats the injectors and exhaust. The loaded run at each service burns it off; see wet stacking.
