Several levels and large glazing
Open living areas facing the water and bedrooms on different floors.
Lilli Pilli's waterfront homes are built around the view, the materials and the light. The air conditioning should fit in quietly: hidden grilles, out-of-sight equipment and no humming box spoiling the deck.

Air conditioning in Lilli Pilli is as much about what you don't see as what you feel. Waterfront homes here have large glazing, several levels and outdoor living areas, so systems need hidden grilles, concealed outdoor equipment and protection from salt air off Port Hacking. Alpha & Omega designs these installs with Daikin ducted and VRV systems.
A beautiful room can be let down by a bulky wall unit or a grille that does not line up with anything. We plan the system with the same care as the joinery.
On renovations and new builds, we work with your architect or builder early, so ceiling space, plant locations and controls are designed in rather than added on.
Waterfront homes in Lilli Pilli often have more than one building to keep comfortable.
Open living areas facing the water and bedrooms on different floors.
Close to the salt and often used in bursts.
Humid air from the pool and doors left open.
Equipment and people add heat all day.
Bring us in at the drawings stage. Plant locations, ceiling voids and grille positions are far easier to get right on paper than after the plasterer has finished.
All three can be made discreet. The right one depends on the size and layout of the house.
| System | Best suited to | How it stays hidden |
|---|---|---|
| Zoned ducted | Single and two-level homes with good ceiling space | Indoor unit in the roof, only slim grilles visible Ducted details → |
| VRV | Large multi-level homes with many rooms | Mix of ducted and concealed indoor units on one outdoor unit VRV details → |
| Multi-split | Renovations where ceiling space is limited | One outdoor unit, with indoor styles chosen to suit each room Multi-split details → |
Daikin's range gives us the flexibility these homes need, from compact ducted units to VRV systems running many concealed indoor units. Every Daikin outdoor coil also carries Blue Fin anti-corrosion treatment for salt air off Port Hacking.
Daikin recognises Alpha & Omega as Residential, Commercial and VRV Aircon Experts.
Yes. Ducted and VRV systems put the indoor equipment in the ceiling, so all you see are slim grilles. Return air can often be hidden in joinery or bulkheads too.
Usually in a screened plant area, under a deck or on the street side of the house, away from the main outdoor living areas and the direct salt spray. They still need airflow and safe service access.
At the drawings stage. That is when ceiling voids, plant areas and grille positions can be planned properly with your architect or builder.
Yes. These spaces usually get their own split or small ducted system, with coated coils and placement chosen to suit the salt and humidity.
For large multi-level homes with many rooms, it often is. One VRV outdoor unit can run many indoor units and heat some rooms while cooling others. Smaller homes are usually well served by zoned ducted.
Every six months for homes right on Port Hacking, because salt and humidity build up on outdoor coils faster than inland.
The same discreet, salt-aware approach suits the rest of the Port Hacking shoreline.
