Can You Install a Split System in an Existing Home?

Yes. Split systems are the easiest air conditioning type to install in an existing home. The indoor unit mounts on a wall, the outdoor unit sits outside, and a small hole connects them. No ceiling cavity access needed, no ducting, no structural changes. Installation takes 2-4 hours and costs from $1,400 fully installed.

Why split systems are perfect for existing homes

Ducted air conditioning requires ceiling cavity access, ducting runs through the roof, and vents cut into every ceiling. In an existing home — especially a Queenslander with tight roof spaces — this is expensive, disruptive, and sometimes impossible. **Split systems avoid all of that:** - **No ceiling work:** The indoor unit is on the wall, not in the ceiling - **No ducting:** Refrigerant pipes run through a single small wall hole - **No structural changes:** Just a wall bracket and a 60mm pipe hole - **Minimal disruption:** 2-4 hours per unit, not 2-3 days - **Lower cost:** $1,400-$2,245 per room vs $8,000-$20,000 for ducted **For whole-home cooling in an existing home, use multi-split:** One outdoor unit connects to 2-5 indoor units in different rooms. You get individual room control without any ceiling work. From $3,395 for a 2-head system.

Frequently Asked Questions

Can you install a split system in a Queenslander?

Yes. Split systems are ideal for Queenslanders because they don't require ceiling cavity access. The indoor unit mounts on the wall and the outdoor unit sits outside. We've installed thousands in Queenslanders across Brisbane.

Do you need to cut holes in my walls?

One small hole (approximately 60mm) is drilled through the external wall for the refrigerant piping and condensate drain. This is sealed properly after installation. No other structural changes are needed.

Can you install in a rental property?

You'll need written permission from the landlord or property manager. We can provide a quote and installation details for them to approve. The unit becomes a fixture of the property once installed.

Will my switchboard need an upgrade?

Not always. If your switchboard has space for a new circuit, no upgrade is needed. If it's old or full (common in pre-2000 homes), a new circuit may require an upgrade. We assess this on site and quote before starting.
