About our split system air conditioning installation
A good split system install is mostly about the details - correct placement, neat pipe and drain routing, proper electrical protection, and thorough commissioning so it runs quiet and efficient.
We help with single split and multi-split installs for bedrooms, living areas, and small offices. If you already have a unit, we can install it. If you want supply and install, we can recommend a matched Daikin or Mitsubishi model sized properly for your room.
What we install
Single split systems
One indoor + one outdoor for bedrooms, living rooms and offices
Multi-split systems
One outdoor + multiple indoors where outdoor space is limited
Back-to-back + longer runs
Simple back-to-back installs, or longer pipe/cable runs as needed
Smart/Wi-Fi setup
App setup, timers, schedules and simple user handover
Electrical works included
Dedicated circuit, outdoor isolator, compliant cabling and protection
How split system installation works
- On-site assessment - confirm placement, access, pipe/drain routing and power requirements
- Clear quote - including scope, inclusions, and any likely extras (long runs, difficult access)
- Mount indoor + outdoor units - level, secure, anti-vibration pads/brackets where required
- Pipework, drain and interconnect - neat routing, penetrations sealed properly
- Electrical works - circuit and isolation installed by a licensed electrician where required
- Commissioning - pressure test, evacuation and charge/commission by a licensed refrigeration mechanic
- Run-up test + demo - modes, filters, basic maintenance and Wi-Fi/app (if used)
Supply options - your unit or ours
- Supply and install - we recommend a matched Daikin or Mitsubishi model sized to the room, ceiling height and glazing
- Install only - if you’ve already picked a unit, we’ll handle compliant installation and commissioning
Quick sizing guide (approximate)
- Up to 15 m² (bedroom/home office): ~2.0-2.5 kW
- 15-25 m² (small living/large bedroom): ~3.2-3.5 kW
- 25-35 m² (medium living): ~4.6-5.0 kW
- 35-50 m² (large living/open plan): ~6.0-7.1 kW+
Actual sizing depends on insulation, windows, ceiling height and sun exposure. We’ll size it properly on site so you get fast, quiet comfort without over- or under-spec.
How much does split system installation cost?
Cost depends on install complexity: back-to-back vs long runs, access (double-storey, roof space, brick walls), mounting method (wall brackets vs slab), and whether a dedicated circuit or switchboard protection is required. We can often quote from photos, or organise a quick site visit.
- Back-to-back installs are usually the simplest and best value
- Long runs / hard access can add labour and materials
- Electrical upgrades may be recommended for capacity and protection (RCD/RCBO, surge, isolator)
Placement tips + upgrades that make a difference
Placement tips (for comfort and quiet)
- Bedrooms - avoid direct draft over the bed; choose a quiet model
- Living areas - aim for clear throw across the room; avoid blowing straight at seating
- Outdoors - allow airflow around the outdoor unit; avoid neighbour windows where possible
Upgrades that are worth it
- Wi-Fi/app control for schedules, remote start and energy tracking
- High-efficiency inverter models (often R32) for lower running costs
- Condensate pumps when gravity drainage isn’t possible
- Surge + RCBO protection at the switchboard where appropriate
Looking after your split system
- Filters - vacuum/rinse monthly in peak seasons
- Indoor coil + drain - periodic cleaning helps prevent odours and blockages
- Outdoor unit - keep leaves and obstructions clear for airflow

Quick FAQs
Can you install where there’s no existing power or cabling?
Yes - our electrician runs the required circuit and isolation switch as part of the job.
How long does installation take?
Many back-to-back installs are completed the same day. Complex runs or multi-splits may take longer - we’ll outline this in your quote.
Do you remove and replace older units?
Yes. We can decommission and responsibly dispose of the old unit, then install your new split system.
Will a split help with winter heating?
Yes - reverse-cycle heating is efficient and fast, and is often cheaper to run than portable resistive heaters.
Can I choose the exact indoor style?
Yes. Wall-mounted is most common, but there are floor console and bulkhead options. We’ll advise what fits your space.
