Connex Electrical supplies and installs split system and ducted air conditioning across Chermside, Aspley, Kedron, Wavell Heights, and inner north Brisbane. We assess your property, present equipment options suited to your home type (established, renovation, unit), and deliver the complete installation — unit supply, electrical circuit, pipework, commissioning, and handover — backed by our lifetime workmanship guarantee.
Chermside’s mix of established post-war homes, renovated properties, and body corporate units creates different air conditioning challenges than outer estates. Older homes often have limited switchboard capacity and ceiling access issues. Units require body corporate approval and noise considerations. Renovations demand integration with existing electrical and structural work. We handle all these scenarios daily across inner Brisbane.
We’re based in North Lakes, 15 minutes from Chermside. Call 0474 207 609 for a free on-site air conditioning quote.

Older Chermside Homes — Switchboard Capacity and Ceiling Access
Many established Chermside homes — particularly post-war construction (1950s–1970s) and weatherboard properties — have electrical and structural challenges that affect air conditioning installation.
Switchboard Capacity in Established Chermside Homes
Older inner Brisbane homes were built before modern air conditioning became standard. Switchboards often have:
- **Limited circuit capacity** (no spare ways for new air conditioning circuits)
- **Undersized main supply cable** from the street
- **Old ceramic fuses** instead of modern circuit breakers
- **No or inadequate RCD (safety switch) protection**
- **Asbestos switchboard backing** (requires specialist removal before upgrade)
We assess your switchboard during the free site visit and confirm whether upgrades are needed before air conditioning installation.
Typical switchboard upgrade costs:
- Safety switch (RCD) add: $180–$500
- New circuit way installation: $200–$500
- Full switchboard replacement (single-phase): $1,500–$3,500
- Asbestos switchboard removal + replacement: $2,000–$4,000
- Three-phase upgrade: $2,500–$5,000+
Switchboard upgrades are quoted separately and must be completed before we install the air conditioning system.
Ceiling Access Challenges
Many older Chermside homes have:
- **Low ceiling cavities** (limited clearance for ductwork or pipe runs)
- **Asbestos ceiling sheeting** (requires specialist handling during penetration work)
- **No roof space access points** (need to create access or work from external walls)
- **Ceiling insulation** blocking access for pipe routing
These factors affect installation complexity and cost. We assess ceiling access during the site visit and explain how it impacts pipe routing options (back-to-back vs. up & over installation) and final pricing.
Body Corporate Units — Approval and Compliance
Air conditioning installation in body corporate properties (units, townhouses, dual-occupancy) requires approval before work begins. Body corporate rules typically control:
- **Outdoor unit placement** (must not affect common property appearance)
- **Noise levels** (outdoor units must comply with noise restrictions)
- **Pipe cover and drainage** (visible pipework must be painted or covered)
- **Structural modifications** (wall penetrations require approval)
We provide technical documentation for body corporate approval:
- Equipment specifications (noise ratings, dimensions, weight)
- Installation diagram showing outdoor unit placement and pipe routing
- Noise compliance information
- Structural impact assessment (wall penetration details)
Most body corporate committees approve air conditioning installations when proper documentation is provided. We’ve completed hundreds of unit installations across inner Brisbane and understand the approval requirements.
Typical body corporate requirements:
- Outdoor unit positioned on private balcony or courtyard (not common property)
- Noise level compliance (usually 50–60 dB at 1 metre)
- Pipe covers painted to match building exterior
- Condensate drainage connected to stormwater (not dripping onto common areas)
We explain body corporate compliance requirements during your quote and provide all necessary documentation at no extra charge.
Chermside Renovations — Integrating Air Conditioning with Building Work
Renovating in Chermside? Air conditioning is easiest to install during the renovation phase when walls are open, ceiling access is available, and electrical work is already planned.
What to coordinate with your builder:
- **Electrical rough-in** — dedicated circuits installed during electrical rough-in phase (cheaper than retrofitting after walls close)
- **Indoor unit wall reinforcement** — ensure framing can support wall-mounted units (particularly important for plasterboard walls)
- **Outdoor unit positioning** — confirm placement with builder before decking, paving, or landscaping finalized
- **Pipe penetration points** — mark wall penetrations before cladding installed
- **Ceiling access** — create or maintain roof space access points for future service
We work with Chermside builders and renovators regularly. We can attend site meetings during the planning phase to advise on electrical requirements, optimal unit placement, and coordination with building work.
Air conditioning timing in renovation projects:
1. **Planning phase** — we attend site meeting, confirm equipment selection and placement
2. **Electrical rough-in** — dedicated circuits installed by us or coordinated with your electrician
3. **Wall/ceiling close-in** — indoor unit wall reinforcement confirmed, penetration points marked
4. **Final fit-out** — we install units, commission system, and hand over
This staged approach delivers better results and lower costs than retrofitting air conditioning after renovation completion.
Dual-Licensed Electrical + Refrigeration Service
Air conditioning installation in Queensland legally requires two separate licences:
1. **QBCC Electrical Contractor Licence** — for mains power wiring, circuits, switchboard work, and isolation switches
2. **ARC (ARCtick) Refrigeration Licence** — for handling refrigerant gases, pipework, and commissioning refrigeration systems
Many contractors hold only one licence and subcontract the other scope. This creates warranty confusion, coordination delays, and finger-pointing when problems arise.
We hold both licences in-house:
- **QLD Electrical Contractor Licence #92217** (Connex Electrical)
- **ARC Refrigeration Licence #AU42842** (refrigerant handling)
One company, one point of contact, one warranty. If anything goes wrong with the electrical or refrigeration work, you call us — not two different companies arguing about whose responsibility it is.
This is particularly important in body corporate properties where you need clear warranty documentation, and in renovations where coordination between trades matters.
What’s Included in Every Connex Chermside Air Conditioning Installation
Every installation includes:
- Free site assessment with switchboard capacity and ceiling access evaluation
- Room sizing confirmation and equipment selection advice
- Indoor unit mounting on appropriate wall structure with correct clearances
- Outdoor unit placement with secure mounting brackets
- Refrigerant pipework connection with UV-stable insulation
- Condensate drainage installation (connected to stormwater where required)
- Dedicated electrical circuit from switchboard to outdoor unit (where required)
- Electrical isolation switch adjacent to outdoor unit
- Pipe cover or duct installation where required (body corporate compliance)
- Vacuum, pressure test, and refrigerant charge verification
- System commissioning, mode testing, and remote/controller setup
- Clean-up and handover with operating instructions
- Body corporate technical documentation (units/townhouses)
- Manufacturer warranty on equipment + lifetime workmanship guarantee on our installation
Why Lifetime Workmanship Matters
Standard installation warranties run 12 months. After that, you’re paying for any workmanship defects that show up.
Common air conditioning installation failures:
- **Mounting brackets loosen** — outdoor unit vibrates, noise increases, eventual structural failure
- **Pipe insulation degrades** — exposed copper, condensation drips, efficiency loss
- **Electrical connections corrode** — intermittent faults, safety risks, complete failure
- **Condensate drains block** — water leaks inside ceiling, mould growth, structural damage
- **Refrigerant leaks at joints** — system performance drops, expensive re-gas required
These problems are invisible on day one. They show up 2–5 years later — often after the installer’s 12-month workmanship period has expired.
Our lifetime workmanship guarantee means:
If any aspect of our installation work fails due to workmanship defects, we return and fix it at no cost. That includes remounting, re-running pipework, fixing drainage issues, or correcting electrical faults that trace back to our scope of work.
Covered by our guarantee:
- Mounting brackets and structural fixings
- Pipework joints, insulation, and weatherproofing
- Drainage and condensate removal
- Electrical circuit integrity and connections
- Refrigerant system integrity (excluding manufacturer defects)
Not covered (manufacturer warranty applies):
- Compressor or refrigerant system component failures due to manufacturing defects
- Indoor or outdoor unit electronic or mechanical faults
- Remote control or controller failures
- Normal wear and tear on unit components
This is particularly valuable in older Chermside homes where installation conditions are more challenging and in body corporate properties where you need long-term warranty confidence.

Installation-only service (if you’ve already purchased a unit) is $1,120 inc GST for standard back-to-back installations.
Many established Chermside homes built before 1980 have undersized switchboards with limited circuit capacity for air conditioning. We assess your switchboard during the free site visit and confirm whether upgrades are needed. Typical switchboard upgrade costs range from $180–$500 for a safety switch addition up to $1,500–$3,500 for a full single-phase switchboard replacement. Older homes with asbestos switchboard backing require specialist removal and replacement ($2,000–$4,000). Switchboard upgrades are quoted separately and completed before air conditioning installation begins.
Yes — we complete hundreds of body corporate unit installations across inner Brisbane annually. Body corporate properties require approval before installation. We provide all technical documentation (equipment specifications, noise ratings, installation diagrams) at no extra charge to support your approval application. Most body corporate committees approve air conditioning when proper documentation is provided. We ensure installations comply with body corporate requirements: outdoor unit placement on private property, noise compliance, pipe covers painted to match building exterior, and condensate drainage connected to stormwater.
Air conditioning is easiest to install during the renovation phase when walls are open and electrical work is already planned. We coordinate with your builder to install dedicated circuits during electrical rough-in, ensure indoor unit wall reinforcement is built into framing, confirm outdoor unit positioning before paving or landscaping, and mark penetration points before cladding installation. We can attend site meetings during the planning phase to advise on equipment selection and coordinate with building work. This staged approach delivers better results and lower costs than retrofitting air conditioning after renovation completion.
We do both. Our primary service is complete supply and installation packages where we assess your Chermside property, present equipment options suited to your home type (established, renovation, body corporate unit), and deliver the full package. We also provide installation-only service ($1,120 inc GST) if you’ve already purchased a unit. Most Chermside customers prefer the supply + install package because we handle equipment selection matched to inner Brisbane conditions, warranty coordination, and body corporate compliance as a single point of contact.
Mitsubishi Electric, Mitsubishi Heavy Industries, Daikin, and Fujitsu all perform well in Queensland’s climate when installed properly. For body corporate properties and close-proximity installations, we recommend models with low noise ratings (Mitsubishi Electric and Daikin have excellent quiet operation specifications). The brand matters less than correct system sizing for your specific room and installation quality. We supply all major brands and explain which models suit your property type during the quote.
A standard back-to-back split system installation takes 3–4 hours from start to handover. Up and over installations (longer pipe runs through limited ceiling spaces common in older Chermside homes), multi-head systems, or installations requiring new electrical circuits take 5–7 hours. Body corporate installations may require additional time for pipe cover finishing and compliance documentation. Ducted air conditioning installations take 2–3 days depending on home size, ceiling access challenges, and ductwork complexity. We confirm the timeline during your quote.
Yes — it’s a legal requirement. Air conditioning installation requires a QBCC Electrical Contractor Licence (for mains wiring, circuits, and switchboard work) and an ARC (ARCtick) Refrigeration Licence (for handling refrigerant gases and pipework). We hold both in-house: Electrical Contractor #92217 + ARC Refrigeration #AU42842. Many contractors only hold one licence and subcontract the other scope, which creates warranty confusion when problems arise. With us, it’s one company, one warranty covering both electrical and refrigeration work.
