Residential Air Conditioning Sydney
Whole-home ducted systems designed, installed and serviced across Sydney. We size the unit to your floor plan, zone it around how your household actually lives, and give you a real installed price from your address before anyone visits.
Local knowledge
Sydney's housing stock is more varied than almost anywhere in the country. Federation and interwar homes often hide shallow, cut-up roof spaces that call for slimline indoor units and careful duct routing, post-war brick homes usually offer the friendliest cavities, and newer two-storey builds need ceiling and bulkhead outlets split so both levels condition evenly.
The climate pulls in two directions: summer humidity asks for moisture removal, and homes west of the harbour cop hotter afternoons than the coast. We design for both with day and night zoning, return air positioned for the whole floor, and capacity taken from your actual floor plan. Whole-home running costs sit at roughly $1–$2 per hour (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).
The installed price
Priced at the measure
Design first
Capacity comes from your actual floor area, ceiling heights, orientation and glazing — not a bedrooms-based rule of thumb. An oversized system short-cycles, dehumidifies poorly and costs more to run, so getting this number right is most of the job.
Living areas grouped for the day, bedrooms for the night, and a study or media room on its own switch where it earns one. Most 3–4 bedroom homes run best with 4–6 zones, because you are rarely conditioning the whole house at once.
The return-air grille is positioned to serve the whole floor, and outlet positions are chosen for even air throw across each room rather than dumping cold air at the door. On double-storey homes we split outlets across the levels so both condition evenly.
Slimline indoor units suit the shallow cavities common in Federation and interwar homes; post-war brick usually takes a standard unit; where a cavity genuinely cannot carry ducting we design bulkhead runs through hallways and robes instead of forcing it.
The honest comparison
The honest comparison for a Sydney family home — sometimes the multi-head is the right call, and we say so.
| Ducted | Multi-head split | |
|---|---|---|
| Upfront cost | 3-bedroom homes from about $11,000 installed | A 3-head multi typically $5,500–$8,500 installed |
| Inside the rooms | Ceiling outlets and one controller | A wall-mounted head in each room |
| Coverage | Whole home, zoned room group by room group | Only the rooms with heads |
| Outdoors | One condenser sized for the house | One condenser feeding each head |
| Best fit | Family homes conditioning three or more rooms daily | Apartments, rentals and two-to-three-room homes |
How it runs
Enter your address and the calculator sizes a system from your home’s footprint and shows an installed price band in about a minute.
We measure the roof space, walk the floor plan, check the switchboard and agree the zoning. The $99 comes off your final invoice.
Capacity, zone map, outlet positions and the return-air location are locked in before install day, so there are no surprises on the day.
Typically one to three days: ducting and outlets first, then the indoor unit, outdoor condenser, refrigerant pipework and the dedicated electrical circuit.
Pressure-tested and evacuated, charged to manufacturer specification, then the zoning is verified room by room before we call it done.
Controller walkthrough, manufacturer warranty registered, and a servicing schedule so the system stays efficient and the warranty stays valid.
Equipment
Most of our Sydney ducted installs are Daikin or Mitsubishi Electric inverter systems — both offer slimline indoor units for tight cavities, quiet operation and a 5-year manufacturer warranty, and both make corrosion-protected outdoor units we specify for coastal homes. We also install Fujitsu, Panasonic, Samsung and Mitsubishi Heavy Industries where they suit the job or the budget better.
Every current system, with capacities, installed pricing and running-cost estimates, is in the product catalogue — or the calculator will shortlist the right ones for your home automatically.
After the install
Every install carries the manufacturer’s 5-year warranty on the equipment plus a minimum 2-year warranty on our installation workmanship. We register the manufacturer warranty for you at handover.
An annual ducted service is $349 and covers the checks that keep the system efficient and the manufacturer warranty valid — we are the same team for the install and the servicing, so there is one number to call.

Frequently asked
A 3-bedroom single-storey house generally lands in the $11,000–$13,000 band, a typical 4-bedroom house runs $13,000–$16,000, and a 5-bedroom or double-storey home starts around $16,000. For a 2-bedroom house or apartment a multi-head split is usually better value, and we will tell you so. Enter your address on our cost calculator and you will see a sized system and an installed price for your home in about a minute.
Ducted is the answer for whole-home comfort in a family house: zoned, quiet and invisible except for the ceiling outlets. Splits make more sense for apartments, rentals and homes where only a couple of rooms need conditioning, and they cost far less upfront. Enter your address on the calculator and it recommends one or the other from your actual floor plan rather than a rule of thumb.
Not when it is zoned and sized properly. Whole-home running costs sit at roughly $1 to $2 per hour — 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 conditioning only the day or night zones costs much less. Oversizing is the usual culprit behind expensive ducted systems, which is why we size from your actual floor plan rather than bedroom count alone.
If your ductwork is still sound we can often reuse it and replace just the indoor and outdoor units, which comes in well under a new install. Where the ducting has collapsed insulation or an R-22-era layout, the job prices like a new system: $13,000–$16,000 for most 4-bedroom houses. The site measure confirms which path your home takes.
Usually, yes. Slimline indoor units suit the shallow roof spaces common in Federation and interwar homes, and where a cavity genuinely cannot take ducting we look at bulkhead runs through hallways and robes. It is one of the first things we confirm at the site measure, so you are never guessing.
We install across Sydney, with dedicated local teams and suburb guides for the Northern Beaches, Upper North Shore and Lower North Shore. Wherever you are, the process is the same: instant price from your address, then a site measure to fix the number.
Most 3 to 4 bedroom homes run best with 4–6 zones: living areas grouped for the day, bedrooms grouped for the night, and any study or media room on its own switch. Zoning is what keeps a ducted system economical, because you are rarely conditioning the whole house at once.
A straightforward single-storey install is usually done in one to two days. Double-storey homes, bulkhead work or switchboard upgrades can add a day. We confirm the timeframe at the $99 in-home assessment, which comes off your final invoice.
Yes. Every installation is carried out by ARCtick licensed technicians under ARC authorisation AU42906, and we handle the refrigerant handling requirements and electrical certification that go with it. You get manufacturer-backed warranties on Daikin, Mitsubishi Electric and the other brands we fit.
