Turrella sits on the southern bank of Wolli Creek. It is mostly residential, with light industrial units clustered near the station and along the railway line. Those units, often with a mezzanine office above the warehouse floor, heat up quickly under metal roofs.

Air conditioning in Turrella covers two very different jobs. Industrial units have high ceilings, metal roofs and mezzanine offices where heat collects at the top. Homes in the residential streets need quiet, efficient comfort. We size systems for both and position them for easy servicing. Alpha & Omega has worked on commercial and residential sites across Sydney's south since 1989.
Heat rises, and in a warehouse with a metal roof it collects right where the mezzanine office sits. Without proper cooling, that office can be the hottest room in the building.
Treating the office as its own enclosed space, with its own appropriately sized system, is usually far more effective than trying to cool the whole warehouse.
Typical setups for the spaces we see here.
| Space | Common choice | Why |
|---|---|---|
| Mezzanine office | A wall split or ceiling-mounted unit | Targets the office without cooling the warehouse Commercial → |
| Showroom or front office | Split or multi-split | Covers customer areas and private offices Multi-split → |
| Family home | Ducted or splits | Depends on roof space and number of rooms Ducted → |

Treat it as an enclosed room with its own system sized for the heat under the roof, staff and equipment, rather than trying to cool the whole warehouse.
Hot air rises and collects under the metal roof, right where mezzanine offices usually sit.
Every three to six months is common, as dust from industrial activity clogs filters and coils faster.
