Local context

Working in Corporate Park

We service Corporate Park North and the surrounding blocks of Corporate Park, Midrand, with access off the N1 and R101. 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.
