Local knowledge

Split systems in Castlecrag homes

Griffin-era stone houses and later homes built to the conservation ethos, mid-century and architect-designed houses on bushy slopes, with almost no strata and very few standard project homes.. Across that mix, wall splits are the fast path to conditioning the rooms that actually get used — bedrooms on the hot side of the house, a home office, or a living area that only earns cooling a few months a year.

Walter Burley Griffin's bushland conservation suburb of stone houses woven between reserves above Sugarloaf Bay. That shapes the install: we pick head positions for air throw rather than convenience, keep outdoor units off bedrooms and boundary walls where neighbours are close, and spec corrosion-protected coils wherever the street sits inside the coastal band.

Scope of work & pricing

What's included, and what moves the price

Every job is a fixed-price quote after an on-site look. Here's what's in scope, and what moves the number up or down.

What this service includes

  • On-site mounting review (wall, outdoor location, refrigerant line path)
  • Daikin, Mitsubishi Electric or Fujitsu inverter indoor head + outdoor unit
  • Refrigerant lines run through wall cavity (no exposed conduit unless unavoidable)
  • Condensate drain to eave or stormwater point
  • Wall bracket or slab for outdoor unit (where required)
  • Electrical connection to existing GPO or dedicated circuit
  • Vacuum and refrigerant charge per manufacturer spec
  • Wireless remote, controller walkthrough, warranty registration

What moves the price up or down

  • Indoor head capacity (2.5kW, 3.5kW, 5kW, 7.1kW, 8kW+)
  • Single-head vs multi-head (number of indoor units sharing one outdoor)
  • Refrigerant line length (longer runs = more pipework + gas)
  • Outdoor unit mounting (wall bracket adds labour + materials)
  • Wall material (brick / weatherboard / fibro / double-storey reach)
  • Existing power supply (new circuit vs existing GPO)
  • Strata or heritage compliance requirements
  • After-hours or weekend install premium

Not included (quoted separately if needed)

  • Plaster repair around indoor head if mounting requires it
  • Painting after install
  • Strata application paperwork (we can supply specs; lodgement is yours)
  • Brick / masonry core-drilling beyond standard wall penetration
  • Decorative line covers (white plastic conduit), quoted separately
  • Annual servicing (sold separately as a maintenance plan)

Frequently asked

Common questions about split system air conditioning in Castlecrag

How much does a split system cost in Castlecrag including installation?

Single-head: $1,800–$3,200 including installation, depending on capacity. Multi-head (3 heads): $5,500–$8,500 installed. Fixed quote after we see the room and outdoor location.

How much does a split system cost to run?

Roughly 20 to 60 cents per hour for most bedroom and living-room splits, up toward a dollar for the big 7–8kW living-area units on the hottest days. Correct sizing matters most: an inverter matched to the room cruises at low speed, which is where those low running costs come from.

How quiet is a modern split system?

Premium inverter heads sit at 19–24 dB(A) on low fan, which is quieter than a whispered conversation. We size the system so it runs on low most of the time, where inverters are at their quietest and most efficient.

Single split or multi-head for a Castlecrag home?

1–2 rooms cooled occasionally → individual single-head splits. 3–4 rooms regularly → multi-head is often the same total price and a cleaner outdoor look (one condenser instead of three).

Will a split system outdoor unit corrode in Castlecrag?

Castlecrag sits within the coastal salt-air band. We spec Daikin or Mitsubishi Electric units with corrosion-protected ("Blue Fin") coils as standard for Lower North Shore homes.

Can you install a split system on a strata-managed Castlecrag unit?

Yes. We supply the compliance paperwork strata committees ask for (acoustic, mounting, drainage) and coordinate with the building manager on outdoor unit placement.
