Muggy and sticky
Warm, humid air makes rooms feel stuffy and sleep difficult.
- Cooling removes moisture as it runs
- Dry mode on mild, humid days
- Quiet bedroom units
North Bondi climbs from the beach towards Ben Buckler, with apartments and homes facing the ocean. In winter, cold sea-facing walls and windows collect condensation, and many residents fight black mould in bedrooms and wardrobes.
Updated October 2026
Air conditioning in North Bondi is as useful in winter as in summer. Moist ocean air meets cold walls and windows, so condensation forms and mould follows. Reverse cycle heating warms surfaces and dry mode pulls moisture from the air, together with sensible ventilation habits. We set systems up with damp in mind. Alpha & Omega has worked in coastal Sydney homes since 1989.
