Ducted Air Conditioning Narrabeen

For a 3-bedroom single-storey house in Narrabeen, ducted air conditioning costs $11,000 to $13,000 installed. Most 4-bedroom houses land between $13,000 and $16,000, and a 5-bedroom or double-storey home runs $16,000+. For a 2-bedroom house a multi-head split is often the better-value path, and we will say so. Fixed-price quote after the on-site measure, so there are no surprises.

Ducted wins for whole-home comfort: one quiet system, no wall units, every room conditioned and zoned. Splits win on upfront cost when you only need one to three rooms. The crossover sits around three or more rooms conditioned daily; at that point running costs are similar and ducted gives the cleaner finish. Our calculator recommends one or the other from your actual floor plan.

Yes. Most single and double-storey Narrabeen homes have enough ceiling cavity for a standard ducted system. Where post-war cavity height is tight, a slim-line bulkhead install solves it.

Most Narrabeen homes work with 4–6 zones: living, kitchen, master, kids' rooms and rumpus. Independent zone control means you only condition occupied rooms, cutting running cost.

Most Narrabeen installs are 1–3 working days. Day 1 is duct and vent fit-out, day 2 is unit placement and refrigerant pipework, day 3 is electrical, commissioning and clean-up.

Yes. Our licensed electrician runs the dedicated circuit, isolator and controller wiring as part of the ducted install. One contractor, one invoice, one warranty.

For a 3–4 bedroom Narrabeen home you plan to stay in, usually yes. You get one quiet system, no wall units, and zoning keeps running costs close to two or three splits. For a single room or a rental, a split system wins on upfront cost.

Less than most people expect when it's zoned properly. A zoned inverter system typically runs $1–$2 per hour cooling the whole home (based on a typical 3–6kW electrical draw at a $0.35/kWh tariff; an inverter system varies its draw with the load, and zoning cuts it further), and much less conditioning one or two zones. Correct sizing is the biggest factor here, because an oversized system short-cycles and costs more.

It depends on whether your existing ductwork can be reused. If the duct runs and insulation are still sound, swapping just the indoor and outdoor units comes in well under the full-install bands above. Where the ducting is past it, the job prices like a new install: $13,000 to $16,000 for most 4-bedroom houses. We tell you which camp you're in at the measure.
