Air Conditioning Amaroo

Amaroo is late-90s to mid-2000s Gungahlin — the housing stock is old enough that the original builder splits are due for replacement, but young enough that ductwork retrofits are almost always straightforward.

Because most Amaroo homes were built after 2000 to at least 6-star ratings, heating and cooling loads are lower than the older Canberra stock — but that also means undersizing is easy to get wrong. We do a full Manual-J style load calc rather than square-metre rules of thumb, because a 7-star home in Amaroo can be comfortably heated by a system that would be laughed out of a 1970s Weston Creek brick veneer.

Nearly every home in Amaroo has solar-ready wiring or an existing PV array. When we spec a zoned ducted system here, we default to inverter units with high SEER ratings so day-time cooling load runs almost entirely off the roof. MyAir 5 or Daikin Airbase controllers let owners see zone-level runtime against solar generation on their phone.

Two-storey homes near Amaroo shops — very common in this suburb — need dual-return ducted systems to keep the upstairs bedrooms from overheating in summer. Townhouse and duplex sites are usually multi-split or single-zone ducted, depending on whether the body corporate allows roof penetrations.
