Local context
Working in Nasrec
We service Nasrec Industrial and the surrounding blocks of Nasrec, Johannesburg, 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.
