Air conditioning installation in North Brisbane is not one-size-fits-all. Homes across the region vary in age, construction, ceiling access, switchboard capacity, and outdoor unit placement options.
In older suburbs like Kallangur, Petrie and Lawnton, we commonly find limited switchboard capacity, older wiring that may need assessment, restricted outdoor unit locations due to lot size or neighbour proximity, and ceiling spaces that require careful navigation for pipework routing. These factors affect how the install is scoped and priced.
In newer estates like North Lakes, Mango Hill and Griffin, homes are often pre-wired for air conditioning but may still need switchboard upgrades if multiple units are being added, or if the original builder install was minimal. Outdoor unit placement on two-storey homes, pipe run length, and aesthetic pipe cover requirements are common considerations in these areas.
Our team assesses each property individually. We look at the electrical supply, the best indoor and outdoor unit positions, pipe run routing, drainage options, and any structural or access factors that affect the installation scope.
A proper air conditioning installation covers the full scope of work needed to get the system running safely, efficiently, and in line with manufacturer warranty requirements.
Every installation includes both the electrical and refrigeration work completed by our dual-licensed team (QLD Electrical Contractor #92217 + ARC Refrigeration #AU42842). You deal with one company for the entire job — no subcontractors, no coordination headaches.
$1,120 incl GST
Ideal for straightforward installs where the indoor and outdoor units are positioned on opposite sides of the same wall.
From $1,200 incl GST
First 3m included
For installations requiring pipework through ceilings, longer runs, or more complex routing.
From $400 incl GST
Required where gravity drainage is not possible.
Every home is different. Additional costs may apply depending on installation conditions.
All extras are explained before work begins. We do not hide installation costs or absorb complex installation conditions into vague pricing.
Air conditioning installation pricing depends on the property, not just the unit.
Common factors include:
A standard install is straightforward and cost-effective. More complex homes need more labour, more materials, and sometimes additional electrical work. That is why we define the standard install clearly and outline extras upfront.
Incorrect air conditioning installation can lead to poor performance, higher running costs, water leaks, drainage failures, electrical faults, premature compressor wear, and voided manufacturer warranties. The difference between a good install and a bad one is often invisible on day one but shows up within months.
Common problems we see from poor installations include:
We follow manufacturer installation guidelines, use proper vacuum and pressure testing equipment, and commission every system before handover. That protects the warranty, protects the equipment, and means the system performs as it should from day one.
If your suburb is nearby and not listed, contact us and we will confirm service availability.
Air conditioning installation often connects with other electrical work. We also provide:
If your property needs additional safety upgrades, extra circuits, or urgent electrical diagnosis, we can help as part of the broader scope.

Not every home has air conditioning, and not every existing system is still doing its job properly. Here are common reasons Brisbane homeowners book an installation or replacement:
Many older Brisbane homes were built without air conditioning. As summers get hotter and work-from-home becomes more common, adding a split system to key rooms makes a significant difference to comfort and productivity.
If your existing unit runs constantly but the room never reaches temperature, or if it is making unusual noises, leaking water, or producing odours, it may be more cost-effective to replace than repair — especially if the unit is 10+ years old.
Renovations and extensions often change the thermal profile of a home. A room that was previously comfortable may now need dedicated cooling, or the existing system may be undersized for the new layout.
Converting a garage, adding a granny flat, or finishing an upstairs bonus room usually requires a new air conditioning circuit and unit to make the space liveable year-round.
Choosing the right air conditioner depends on room size, ceiling height, insulation, window exposure, and how the space is used. Undersizing leads to a unit that runs constantly and never reaches temperature. Oversizing leads to short-cycling, humidity problems, and wasted energy.
As a rough guide, you need approximately 120–150 watts of cooling capacity per square metre of floor area, adjusted for ceiling height, insulation quality, and sun exposure. A 20sqm bedroom typically needs a 2.5kW unit; a 40sqm living area may need 5–7kW depending on glazing and orientation.
Inverter systems adjust compressor speed to match the load, running more efficiently and quietly than fixed-speed units. Almost all modern split systems are inverter-driven, and we recommend them for both comfort and running cost reasons.
We install all major brands including Daikin, Mitsubishi Electric, Mitsubishi Heavy Industries, Fujitsu, Samsung, LG, Panasonic, and Carrier. We can recommend based on budget, features, and warranty terms, or install a unit you have already purchased.
We inspect the property, confirm the best indoor and outdoor unit positions, assess electrical supply and switchboard capacity, measure pipe run length, and provide a fixed-price quote that covers the full installation scope.
On the scheduled day, we mount the indoor unit, position the outdoor unit, run refrigerant pipework and drainage, install the dedicated electrical circuit, and connect everything according to manufacturer specifications.
We vacuum the refrigerant lines, pressure test for leaks, release or charge refrigerant as required, then commission the system through all modes — cooling, heating, fan, and auto. We verify airflow, drainage, and electrical readings before handover.
We walk you through the remote control, explain the modes and settings, confirm the warranty registration process, clean up the work area, and make sure you are comfortable operating the system before we leave.
A standard back-to-back split system installation starts from $1,120 incl GST. More complex installations with longer pipe runs, difficult access, or switchboard upgrades are quoted on site.
Many air conditioning systems require a dedicated circuit. If your switchboard is full or outdated, a switchboard upgrade may be needed before or during the AC installation.
A standard single split system installation typically takes 3–5 hours. Multi-head systems or installations requiring longer pipe runs or switchboard work may take a full day.
Yes. We regularly install split systems in older Brisbane homes. We assess ceiling access, wall structure, electrical supply, and outdoor unit placement to find the best solution for the property.
We install all major brands including Daikin, Mitsubishi Electric, Mitsubishi Heavy Industries, Fujitsu, Samsung, LG, Panasonic, and Carrier. We can supply or install customer-supplied units.
Yes, same-day installation is available on suitable jobs where stock and scheduling allow. Call 0474 207 609 to check availability.
A back-to-back installation means the indoor and outdoor units are mounted on opposite sides of the same wall, keeping pipe runs short (typically under 3 metres). This is the most cost-effective installation type.
As a guide, a 20sqm bedroom typically needs a 2.5kW unit, a 35sqm living area needs around 5kW, and larger open-plan spaces may need 7kW or more. We assess room size, ceiling height, insulation, and window exposure to recommend the right capacity.
Yes. Connex Electrical holds both a QLD Electrical Contractor Licence (#92217) and an ARC Refrigeration Licence (#AU42842). We complete the full installation in-house — no subcontractors.
Yes. We remove old units, recover refrigerant safely, and install the replacement system. Existing pipework and electrical circuits can sometimes be reused if they are in good condition and correctly sized.
