Local context

Working in Robertville

We service Robertville Industrial and the surrounding blocks of Robertville, Roodepoort, with access off the N1 and N12. 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.
