Local context
Working in Cleveland
We service Cleveland Industrial and the surrounding blocks of Cleveland, Johannesburg, with access off the M2 and N3. 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.
