Why proper installation matters
Correct sizing, positioning and electrical connection are the difference between a system that runs efficiently for years and one that struggles and drives up your power bills.
In Queensland, any air conditioner above 3.5kW needs its own dedicated circuit back to the switchboard, and refrigerant work must be done by a suitably licensed technician. We handle the electrical side properly and install to the manufacturer's specifications.
What's included
Supply and installation of split system air conditioning
Correct sizing and positioning for your space
A dedicated circuit and compliant electrical connection
Servicing and maintenance to keep units running efficiently
Repairs and fault finding
What size air conditioner do you need?
As a rough guide, a 2.5kW unit suits a small bedroom, 3.5kW a larger bedroom or small living area, and 5 to 7kW an open-plan living space, but ceiling height, insulation and how much sun the room gets all matter.
We will assess your space and recommend the right size, so you are not paying for more than you need or fighting a unit that is too small.
What split system installation costs
Most Moreton Bay split system installs land between roughly $1,300 and $3,500 fully installed, depending on the unit size and brand, the pipe run, access, and whether a dedicated circuit or switchboard work is needed.
We quote fixed-price after assessing your space.
