Local context
Working in Jet Park
We service Jet Park Industrial Estate and the surrounding blocks of Jet Park, Boksburg, with access off the R21 and N12 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.
