Air Conditioning Collaroy Plateau

The plateau sits above Collaroy Beach, reducing direct salt spray but catching more wind. Standard outdoor units are generally adequate. Wall brackets on the eastern brow above Anzac Avenue need wind-rated fixings, and a condenser placed on a gusty corner of the escarpment works harder to reject heat than one tucked into a sheltered side passage.

Predominantly freestanding 3 to 4 bedroom homes with good roof cavities and block sizes suitable for ducted or multi-split systems. The level blocks in the middle of the plateau make ground-level condensers easy, while the houses stepping down the eastern and western edges often have living areas below the street and may suit a multi-head system instead.

Many homes have large east-facing windows for ocean views, which increases morning heat gain and should be factored into heat-load calculations. On the escarpment edge that glass is often full height and unshaded, so a living room facing Long Reef can need noticeably more capacity in the morning than a west-facing room of the same size.

The plateau's 1950s to 1970s fibro and brick-veneer homes typically have minimal wall and ceiling insulation. A heat-load calculation often returns 20 to 30% higher capacity than equivalent modern builds. Fibro walls may also contain asbestos, so the quote should state how the pipework penetration is being handled and by whom.
