Ductless Split System Installation

Looking to cool a single room or a few areas of your home? Ductless split systems under 18kW are the go-to choice for efficient, cost-effective air conditioning in Brisbane homes.

We supply and install split systems for:

  • Bedrooms and living areas
  • Home offices and studios
  • Granny flats and extensions

Every system is sized properly to match your space, ensuring performance and energy efficiency. We help you choose the right unit and complete the install with clean cabling, safe electrical connections, and tidy indoor/outdoor placement.

Ductless Split System Servicing

Air conditioning units work hard — especially during Queensland summers. Regular servicing keeps your system running efficiently, reduces wear and tear, and helps avoid breakdowns.

Our split system servicing includes:

  • Hydro washing

  • Performance Testing

We recommend scheduling a service before summer kicks in, or every 12 months if used regularly. A well-maintained unit runs cooler, cleaner, and cheaper.

Performance Testing

Not sure if your system is working like it should? Maybe it’s cooling unevenly, running longer than usual, or your power bills are creeping up.

We carry out performance testing on residential AC systems under 18kW to assess:

  • Cooling efficiency

  • Airflow and fan performance

  • Refrigerant levels

  • Power draw and cycling

Our technicians will give you clear results and honest recommendations — whether your system just needs a tweak or it’s time to consider an upgrade.

Hydro Cleaning

Even the best AC system gets clogged over time — with dust, mould, pet hair, and other airborne particles. A standard service can’t always reach deep inside the unit. That’s where hydro cleaning comes in.

We use high-pressure, targeted water cleaning to flush out the internal coils and fan barrel. This process:

  • Restores airflow
  • Removes contaminants
  • Improves energy efficiency
  • Eliminates odours

It’s especially valuable for allergy-prone households or if your unit hasn’t had a deep clean in a while. The result? Cleaner, healthier air and better cooling — without replacing your system.
