Technical Protocol
How a call-out actually runs
The difference between a repair that holds and one that returns in six weeks is method. This is ours.
01
Call or WhatsApp the fault
Send a photo of the unit and its data plate. We identify the model and likely fault before dispatching, so the right parts travel with the technician.
02
Measured diagnosis on site
Gauges, clamp meter and temperature readings — not guesswork. You see the readings and we explain what they mean in plain language.
03
Written quote before work
Parts and labour itemised. Nothing gets replaced without your go-ahead, and the diagnostic fee is credited against the repair.
04
Repair, commission, record
We restore temperature, clean what should have been cleaned, and leave a service record with running amps and delivered temperatures.
Hyper-Local Response Engine
Suburbs we cover from our Randburg base
Each area page carries local detail — property mix, the equipment we typically find there, travel times and recent work — because a Ferndale kitchen and a Randpark Ridge home need very different attention.
Outside these suburbs? Call us anyway — we regularly travel further for commercial refrigeration and cold room work across northern Johannesburg.
