Local context

Working in Chamdor

We service Chamdor Industrial and the surrounding blocks of Chamdor, Krugersdorp, with access off the N14 and R28. 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.
