Supply and Install 2 Daikin Split System Air Conditioners
Case Study: Two Daikin Split System Installations in Sarina, Queensland
Project Overview
When it comes to year-round comfort in Queensland, a reliable air conditioning setup is essential, especially in a family home where different areas have different needs. Climate Air Solutions was recently engaged to complete an air conditioning upgrade at a residential property in Sarina, Queensland, where the homeowner wanted improved cooling and heating performance across two key zones of the home.
The property had an existing air conditioning system that was no longer meeting the household’s needs. After discussing the client’s requirements and inspecting the home layout, our team recommended a dual split system solution: one unit designed for efficient bedroom comfort and a second, larger capacity system designed to handle the open-plan living space.
The job involved safely decommissioning the existing air conditioner, then supplying and installing:
- 1 x 2.5kW Daikin reverse cycle split system for the kids bedroom
- 1 x 7.1kW Daikin inverter split system for the main living room
To keep the installation clean and cost-effective, the outdoor units were mounted on existing wall brackets, and we were able to reuse the existing isolator.
The Client’s Requirements
The homeowner had two clear goals:
- Comfort for the kids bedroom
The existing setup wasn’t providing consistent cooling in the bedroom, and the client wanted a quieter, more efficient unit that could maintain a stable temperature overnight. - Powerful performance for the main living area
The living room was a larger, high-use space where the family spent most of their time. The client needed an air conditioner that could cool quickly in summer and provide effective heating during cooler months.
They also sought a solution that was aesthetically pleasing, utilised high-quality equipment, and was installed by a qualified team with strong local knowledge.
Site Inspection and System Selection
Before commencing works, Climate Air Solutions carried out an on-site inspection to confirm:
- Room sizes and airflow requirements
- The most suitable wall locations for indoor units
- Outdoor unit placement and service clearances
- Existing electrical infrastructure and isolator condition
- Pipe run pathways and drainage points
- Overall installation feasibility and aesthetics
Based on the home’s layout and the client’s comfort needs, Daikin was selected due to its strong reputation for reliability, energy efficiency, and performance in Australian conditions.
Step 1: Decommissioning the Existing Air Conditioner
A key part of this project was the safe removal of the old air conditioning system.
Decommissioning is not simply “taking a unit off the wall.” It requires the correct process to ensure the system is removed safely, responsibly, and in line with Australian standards. Our technicians:
- Isolated power to the unit
- Recovered and handled refrigerant appropriately
- Disconnected pipework, electrical connections, and drainage
- Removed the indoor and outdoor components
- Prepared the installation areas for the new Daikin systems
This ensured the home was ready for the new equipment and that the replacement installation could proceed smoothly.
Step 2: Installing the 2.5kW Daikin Reverse Cycle Split System (Kids Bedroom)
The first installation was a 2.5kW Daikin reverse cycle split system in the kids’ bedroom. This capacity was ideal for a bedroom space, offering:
- Fast and efficient cooling in summer
- Comfortable heating in winter
- Quiet operation for sleep
- Improved energy efficiency compared to older systems
Our installation process included:
- Mounting the indoor unit in the optimal position for airflow
- Running new refrigeration pipework neatly through the wall cavity
- Installing a suitable condensate drain line
- Pressure testing the system for leaks
- Evacuating the pipework using a vacuum pump
- Releasing refrigerant and commissioning the unit
Once installed, the system was tested to ensure correct temperature delivery, quiet operation, and smooth performance.
Step 3: Installing the 7.1kW Daikin Inverter Split System (Main Living Room)
The second unit was a 7.1kW Daikin inverter split system, installed in the home’s main living room. This was a larger capacity system designed to manage the higher heat load of an open-plan space, particularly important in Sarina, where summer conditions can be hot and humid.
The 7.1kW Daikin inverter model was chosen because it provides:
- Strong cooling capacity for larger areas
- Inverter technology for stable temperatures and lower running costs
- Reliable heating performance for winter nights
- Efficient modulation rather than constant stop-start cycling
Our team positioned the indoor unit for maximum airflow coverage across the living space, ensuring the conditioned air could reach the main seating and family areas effectively.
Outdoor Air Conditioner Unit Installation: Reusing Existing Wall Brackets
One of the key efficiencies of this job was that the outdoor units could be mounted using existing wall brackets. After inspection, our technicians confirmed the brackets were:
- Structurally sound
- Correctly anchored
- Suitable for the new Daikin outdoor units
- Positioned to allow adequate airflow and service access
Reusing the existing brackets helped reduce unnecessary hardware replacement while still ensuring the installation remained safe, compliant, and secure.
Electrical Work: Reusing the Existing Isolator
To keep the installation efficient, Climate Air Solutions also reused the existing electrical isolator. Prior to reuse, we inspected the isolator to confirm:
- It was in good working condition
- It met safety requirements
- Connections were secure and suitable for the new systems
Reusing the isolator is only done when it is safe and compliant to do so. This step reduced unnecessary electrical replacement while maintaining the required safety standard.
Testing, Commissioning, and Handover
Once both systems were installed, our technicians completed a full commissioning process. This included:
- Verifying refrigerant pipe integrity
- Confirming system pressures and operating temperatures
- Testing both units in heating and cooling modes
- Ensuring drains were flowing correctly
- Checking remote functions and system settings
- Confirming stable inverter operation
We then provided the homeowner with a full walkthrough, including:
- How to operate each remote
- Recommended temperature settings for efficiency
- Cleaning and filter maintenance tips
- Warranty and servicing advice
Final Result
The Sarina homeowner now has a modern, efficient air conditioning solution tailored to their family’s needs.
- The 2.5kW Daikin split system provides quiet, reliable comfort for the kids bedroom.
- The 7.1kW Daikin inverter split system delivers powerful climate control for the main living room.
By safely decommissioning the old unit, reusing the existing wall brackets and isolator where appropriate, and completing a clean professional installation, Climate Air Solutions delivered a result that was both cost-effective and high quality.
