Air Conditioning Dural NSW — Splits, Multi & Ducted Installers

Air conditioning installation in Dural ranges from $1,400 for a single 2.5kW split in a small bedroom up to $26,500+ for a fully ducted reverse cycle system in a large acreage home in 2026. A standard 5kW high-wall split for a living area runs $2,200–$3,200, a 3-zone multi-split sits at $6,500–$10,500, and a typical 14–16kW ducted system for a larger 4–5 bedroom Dural home runs $13,000–$19,500*. Because most of Dural has no reticulated natural gas, ducted reverse cycle is the dominant install — it does heating AND cooling. Bushfire-prone lots add $300–$1,500* for ember-resistant condenser screening. Older homestead homes with original switchboards often need another $300–$600 for a dedicated circuit or $1,200–$2,500 for a single-phase upgrade. All refrigerant work must be done by an ARCtick licensed technician — verify at arctick.org.

For a typical 25m² Dural living room with average insulation and mixed sun exposure, you need a 5kW high-wall split — the standard size that handles the suburb's mean 27.5°C January maximum plus the occasional 35–38°C heatwave day. For a whole 4-bedroom acreage home (typical Dural footprint 220–300m²), a 14–16kW ducted reverse cycle is the standard sizing. Dural's 208m elevation means the suburb runs roughly 3–5°C cooler than Cumberland Plain inland suburbs like Penrith or Auburn — so sizing is less aggressive than further west. But because most of Dural has no natural gas, the same unit also has to handle winter heating, where mean July minimums sit around 6.5°C.

For a standard single split or multi-split on a freestanding home, no — the install is Exempt Development under the NSW SEPP (Exempt and Complying Development Codes) 2008, subject to noise (5 dB above background under the POEO Noise Control Regulation 2017), front building line setbacks, and not affecting a heritage item. No DA, no certifier. The twist in Dural is the suburb is split between TWO councils: the majority sits in The Hills Shire (North Ward), with eastern portions in Hornsby Shire (Ward A). Check which side you're on before submitting any work that needs a Section 10.7(2) Planning Certificate. Heritage items like St Jude's Anglican Church (1846, on the Register of the National Estate) and heritage cottages along Old Northern Road may trigger a DA if a condenser is street-visible. If your lot is on bushfire-prone land (much of Dural is), the condenser placement must comply with AS 3959-2018 and Planning for Bush Fire Protection 2019*.

Yes. A significant proportion of Dural sits on NSW Rural Fire Service-certified Bushfire Prone Land — the suburb borders Berowra Valley National Park, Galston Gorge and the Cattai catchment. Where your lot has a Bushfire Attack Level (BAL) rating, the outdoor condenser unit, brackets, screening and any penetrations into the building envelope must comply with AS 3959-2018 Construction of Buildings in Bushfire-Prone Areas and Planning for Bush Fire Protection 2019. In practice that means an ember-resistant screen or enclosure around the condenser, non-combustible mounting, and sealed penetrations where the refrigerant lineset enters the wall. Add roughly $300–$1,500* depending on BAL rating and screening type. A qualified Bushfire Planning and Design (BPAD) accredited consultant determines the BAL — your council will tell you if your lot needs one.

Yes, two of them. Every air conditioning installer in Dural must hold (a) an ARCtick refrigerant handling licence from the Australian Refrigeration Council — mandatory under Commonwealth ozone legislation for anyone who handles refrigerant gas, no exceptions — and (b) a NSW Fair Trading electrical contractor licence for the electrical wiring side. An installer with only one of these cannot legally complete the job. Verify the electrical licence at verify.licence.nsw.gov.au and the ARCtick licence at arctick.org — both registers are public and take 30 seconds. Using an unlicensed installer voids your manufacturer warranty, can void your home insurance, and exposes you to fines if refrigerant is mishandled.

In NSW, residential air conditioners are governed by the Protection of the Environment Operations (Noise Control) Regulation 2017. The practical rule is the outdoor unit cannot exceed 5 dB above the background noise level at the neighbouring residential boundary during operating hours, and is generally restricted between 10pm and 7am on weeknights and 10pm and 8am on weekends and public holidays. On Dural's larger acreage lots the noise issue is usually less acute than tighter inland suburbs because of the setback distances, but on smaller infill lots around Round Corner the placement matters. Modern inverter splits are typically rated 40–55 dB(A) outdoor at 1m. Anti-vibration mounting pads, distance from the boundary, and acoustic screening are the standard fixes. Both Hills Shire and Hornsby Shire councils can issue noise abatement notices under the POEO Act.

This is common on Dural homes built between the late 1970s and 1990s — many of the older acreage homesteads through Galston Road, Kenthurst Road and Old Northern Road have original switchboards sized for the loads of that era. Adding a 7kW or larger split (typical for a Dural living area) on a shared circuit causes the breaker to trip when the compressor cycles on at the same time as the oven, kettle or pool pump. The fix is twofold: install a new dedicated 15–20A circuit just for the aircon ($300–$600*), and if the main switchboard is itself near capacity or pre-rewireable-fuse era, upgrade the switchboard to a modern RCD/RCBO board ($1,200–$2,500* single phase, $2,500–$4,500* if upgrading to three phase for a large ducted system). Three phase is worth pricing on bigger ducted installs.

For a typical Dural acreage home of 220–300m² on a 4,000m²+ lot, ducted reverse cycle is the dominant install — it gives whole-home zoned cooling AND heating from one system, and because most of Dural has no reticulated natural gas, the ducted system is doing both jobs all year. A 14–16kW ducted unit ($13,000–$19,500*) is the typical sizing for a 4-bedroom Dural home, with 6–7 zones controlled room-by-room. Single splits are still the cheaper choice for a single room or open-plan living area ($2,200–$5,500* for 5–10kW), but on a larger home you end up running 4–5 separate splits that cost more in total than one ducted and run less efficiently. Multi-split (one outdoor, 2–5 indoor heads) is the middle ground.

Dural is split between two LGAs. The majority of the suburb — including Round Corner and most of the area south and west of Old Northern Road — sits in The Hills Shire Council (North Ward). The eastern portions, broadly east of New Line Road and toward Galston, sit in Hornsby Shire Council (Ward A). For a standard Exempt Development aircon install on a freestanding home neither council needs to approve it, but if you're checking a 10.7 Planning Certificate, a heritage overlay, the Bushfire Prone Land map, or any DCP rule that touches the property, you need to go to the council your lot actually sits in. Your rates notice tells you. Don't assume — Dural is one of the few Sydney suburbs where neighbours can be in different councils.
