Generator faults we fix in Parktown and Houghton

Local conditions
Basements under Killarney, gardens in Houghton
A Killarney block keeps its generator in a basement plant room or a corner of the parkade, wired through a changeover the trustees have never seen operate. The caretaker opens the door and a transfer test is booked for a quiet hour.
In Houghton Estate and Lower Houghton, on both sides of the M1, the set sits in a garden bed or beside the garage, idle for months and then expected to carry a whole house; we agree who will be home.
- Plant rooms opened by the caretaker
- Lifts and pumps proved back on mains
- Idle home sets checked for stale diesel and a weak battery
Response
On site in Parktown and Houghton in 1–2 hours
Technicians on site in 1–2 hours, 24/7. Oxford Road, Jan Smuts Avenue and Louis Botha Avenue are the main routes and the M1 cuts through Killarney and Houghton, so a technician comes in from the city side or from Rosebank. Tell us the parkade height, or which gate to use.
Look at the fuel gauge, main breaker, emergency stop and controller message and nothing else; a set that fires and dies gets no more tries, and the changeover stays shut. A photo of the controller and nameplate puts the probable parts in the van; emergency generator repair covers the night call.
Every make
Makes we repair from Killarney to Westcliff
We Service & Repair All Generator Brands. Under the blocks and behind the offices that means canopied diesel sets on Perkins, Cummins or John Deere engines with Stamford or Leroy-Somer alternators and Deep Sea Electronics or ComAp controllers; on the stands, silent diesels from Kipor, Bundu Power, Pramac, SDMO and Mac Afric, and gas standby units whose LPG pipework is a registered gas installer’s work. Each has a brand page.
Prevention
Why a set here fails a second time
Sets come back to us when the cause outlives the repair: a Killarney block fits a new battery while its charger goes on overcharging, a Houghton set restarts on last year’s diesel, a reset contactor sticks again. Our report lists the rest.
Clearing that list is servicing: our Parktown and Houghton generator service and maintenance page covers the visit at a Killarney plant room, a medical suite or a Houghton home, the intervals load shedding imposes and the plans trustees and practice managers use. How a fault is traced is on generator repairs; next door we work in Rosebank, the Johannesburg CBD and Norwood and Orange Grove, and across Johannesburg.

FAQ
Frequently asked questions
Our Killarney block’s generator starts but the lifts stay off. Is it too small?
Usually not. The engine starts, so battery and controller are fine; the changeover has not moved the load across: a contactor, sensing or breaker fault. See ATS and changeover problems.
Can you repair the generator at our Parktown suite without disturbing patients?
Yes. The set is isolated for the repair while the rooms stay on mains. Only the transfer test touches the fridges and equipment, and that is booked before opening or after the last patient; we work 24/7.
Our Houghton generator has not run since winter and now will not start. Is it the battery?
Usually the battery or its charger, with old diesel close behind: condensation gathers in a standing tank and sediment chokes the filter. We test the battery under crank, then the charger, then the fuel.
Do you repair home standby sets in Parktown West, Westcliff, Saxonwold and Forest Town?
Yes. The usual call there is a silent diesel or gas set that stood too long beside the garage, so we bring battery, charger and fuel parts; see home generator services.
