Choose the right format
Air conditioning systems matched to the space
The system type should follow the building, comfort priorities, control needs and installation constraints—not the other way around.
Split systems
Direct, efficient comfort for a room or defined area with a wall-mounted indoor unit and outdoor condenser.
Explore split systems
Multi-split systems
Several indoor units connected to one outdoor unit—useful where outdoor space is limited but rooms need separate control.
Compare multi-split
A useful design considers heat load, insulation, glazing, orientation, occupancy and how the home is actually used.
Why design matters
Comfort is a layout problem before it is an equipment problem
A system can be a respected brand and still disappoint if it is poorly sized, badly positioned or commissioned without balancing airflow.
- Room-by-room capacity and return-air planning
- Roof-space, access and maintenance clearance
- Outdoor-unit noise, drainage and neighbour impacts
- Zoning that respects minimum airflow requirements
- Electrical capacity and any switchboard work
- Clear inclusions, exclusions and handover documentation

Ducted, split or multi-split?
Use this quick comparison to frame the site assessment. It is guidance, not a substitute for heat-load calculations or an inspection. The original KYNEX resource adds practical detail through ducted air conditioning Sydney.
Ducted air conditioning
A central indoor unit distributes conditioned air through insulated ducts and discreet ceiling or wall outlets. Zones can separate selected areas, subject to system airflow requirements.

What happens from enquiry to handover
Understand the property
Discuss rooms, layout, comfort problems, building type, strata constraints and timing.
Inspect and design
Assess capacity, equipment locations, duct or pipe routes, drainage, power and access.
Itemise the scope
Confirm equipment, labour, controls, electrical items, finishes, exclusions and assumptions.
Install and commission
Complete the work, test operation, balance airflow where applicable and explain controls.
Document and hand over
Provide the agreed warranty and operating information, subject to confirmed terms.
Maintain access
Plan filter, drain, coil and component access so servicing is practical later.
Cost clarity
What changes an installed quote?
Equipment capacity is only one part of the price. Compare scope line by line.
| Cost driver | Why it matters | What to ask |
|---|---|---|
| Capacity and equipment | Larger systems and premium controls can change supply cost. | What load assumptions support the selected capacity? |
| Zones and sensors | More control hardware, dampers and commissioning add complexity. | Which rooms are grouped and what minimum airflow is required? |
| Access and duct routes | Tight roofs, multiple levels and finished surfaces affect labour. | What access or ceiling work is included? |
| Electrical work | New circuits, isolators or switchboard upgrades may be required. | Is all electrical work itemised? |
| Finishes and disposal | Patching, grilles, penetrations and removal of old equipment vary. | Who completes making-good and disposal? |

Straight answers
Common Sydney air conditioning questions
Can ducted air conditioning be installed in an existing Sydney home?
Often, yes. Suitability depends on usable roof or underfloor space, access for ducts and indoor equipment, electrical capacity, room layout and the intended outlet positions. A site assessment is the reliable way to confirm it.
How much does ducted air conditioning cost in Sydney?
There is no responsible fixed figure without a design. Capacity, zones, controls, roof access, switchboard work, duct routes, finishes and equipment brand all affect the installed price. KYNEX provides an itemised quote after assessing the property.
Is ducted or split-system air conditioning better?
Ducted systems suit discreet whole-home comfort and central zoning; split systems can be more practical for one or two rooms or properties with limited roof space. Multi-split can bridge the gap where several rooms need independent indoor units.
Do apartments need strata approval?
Usually the by-laws, common-property impacts, exterior appearance, drainage and noise conditions must be checked before work starts. Requirements vary by scheme, so obtain written approval rather than assuming permission.
How long does installation take?
A straightforward single split is commonly completed more quickly than a multi-room or ducted installation. Access, electrical work, ceiling work, zoning and commissioning determine the programme, which should be confirmed in the written quote.
