Aircon Installation Adelaide
Aircon installation in Adelaide covers four broad system classes — single-head split systems, multi-head splits, ducted reverse-cycle, and evaporative cooling — and the right choice depends as much on the climate zone and the room layout as it does on the brand. A standard 7kW split-system installation in Adelaide takes a half-day and costs $2,800–$3,800 fitted, including commissioning paperwork for the warranty. A 4-zone ducted retrofit runs 2–3 days and lands somewhere between $9,500 and $13,500. The numbers are real, the install is the part that has to be right.
We’re ARC-licensed Adelaide installers, and we’ll get back to you within 24–48 hours, with no obligation to proceed. The form takes 90 seconds. The quote will tell you which class of system fits, what kW capacity is correct for the rooms you actually use, and which brand we’re genuinely authorised to fit.
What’s included in every aircon installation quote
Every quote we send itemises the same six things — no vague “from $X” lines, no surprises on the day:
- Site survey — phone, photo or in-person depending on the job. Heritage retrofits and ducted always get an in-person visit.
- Sizing calculation — kW capacity matched to room m², ceiling height, insulation grade and the climate zone. Salisbury and Modbury jobs get a +20% loading; Stirling and Mount Barker get the cold-ambient capacity check (rated kW at 2°C, not nameplate).
- Brand and model recommendation — the brands the installer is authorised to fit, with a short note on which suits the climate (Daikin Cora US7 for Glenelg, Mitsubishi Hyper Heating FH for Mount Barker).
- Supply and install pricing — equipment, labour, mounting hardware, refrigerant lines, electrical and clean-up itemised.
- Commissioning — vacuum to spec, refrigerant charge confirmed, performance test, and the paperwork the manufacturer requires for warranty registration.
- Workmanship guarantee — five years standard, in writing.
The four classes of installation
Split-system installation
The Adelaide standard for one-room and small-house jobs. Single-head wall-mounts cover one room (a 2.5kW unit is enough for most bedrooms; 5kW is the typical living-room call; 7kW handles open-plan kitchens up to about 50m²). Split-system installation is fast — most jobs are a half-day — and the brand range is broad.
Multi-head split installation
One outdoor compressor running 2–5 indoor heads. The right choice when ducted isn’t viable (heritage ceilings without roof void, Norwood and Prospect bungalows, character terraces) but you need more than one room cooled. Multi-head 4-head systems sit in the $7,500–$11,000 fitted range.
Ducted reverse-cycle installation
Ducted air conditioning — whole-home heating and cooling with zone control — is the premium retrofit market. Burnside, Mitcham, the Hills, and the new northern growth corridors are the typical jobs. Expect 2–3 days on-site for a standard 4-bedroom retrofit, and budget $9,000–$14,000 for a 4-zone system, more for 6+ zones or higher kW capacity.
Evaporative installation
Evaporative cooling is the SA-specific option — works beautifully on dry inland plains, underperforms on the humid coast. Roof-mounted, low running cost, $4,000–$7,500 fitted. Best suited to Salisbury, Modbury, Mawson Lakes and the inland north.

These are realistic 2026 ranges across Adelaide installers. Your quote will land inside them — or below, if there’s an active rebate or off-season discount running. The deeper aircon installation cost guide walks through the line items.

Why our installation lasts
The four things that separate a good install from a callback at year three:
- Vacuum the line-set to the right depth and hold time. Moisture in the lines is what destroys compressors. The vacuum gauge on the manifold is the proof.
- Torque the flare nuts to the manufacturer spec. Over-torqued flares crack; under-torqued flares leak refrigerant. Both fail the warranty.
- Check the drain fall. Indoor unit condensate has to flow downhill — get the gradient wrong and the unit dribbles onto the wall in the first humid week.
- Mount the brackets to the structure, not to the cladding. Outdoor unit on a rendered wall without proper masonry fixings rattles loose inside two summers.
We know the drill. The five-year workmanship guarantee is in writing.

Frequently asked questions
How long does aircon installation take in Adelaide? A single-head split system is typically a half-day job. A multi-head split runs a full day. A ducted reverse-cycle retrofit on a 4-bedroom home is 2–3 days, longer if the roof void is restricted (heritage homes, character cottages with plaster ceilings).
Do I need a permit for aircon installation in Adelaide? Most residential aircon installs don’t require council approval. Heritage-listed properties and character overlay zones (parts of Norwood, Prospect, Walkerville, North Adelaide) sometimes restrict visible-from-street condenser placement — we flag it in the quote and work around it. Bushfire-prone properties in the Hills have specific clearance rules under the Building Code.
What size aircon do I need? The rule of thumb in Adelaide is 0.15kW per m² for a well-insulated room with normal ceiling height, plus a +20% loading for inland heat-load suburbs and a +10% loading for west-facing rooms. A 30m² living room sits in the 5kW band; a 50m² open-plan kitchen-living usually needs 7kW. The sizing guide article walks through it.
What’s the warranty on a new install? Manufacturer warranties are 5–7 years on most splits and ducted systems. We offer a 5-year workmanship warranty on top — covering the install itself, not the equipment. Both warranties are in writing on every quote.
Can you install on a Saturday? Yes. Saturday install slots are limited but available. Flag it in the notes when you submit the quote.
Will you remove my old unit? Yes — every quote includes removal and responsible disposal of the existing unit, including refrigerant recovery (mandatory under Australian Refrigerant Reclaim Australia rules).
