Local context
Working in Witfield
We service Witfield Industrial and the surrounding blocks of Witfield, Boksburg, with access off the N12 and R21. Highveld summers push afternoon ambients past 32 °C with heavy thunderstorm humidity, so condensers here are sized with a generous approach and cleaned before every summer.
