Split System Air Conditioner Installation Kahibah NSW

Installing a Fujitsu Split System Air Conditioner

Case Study: Fujitsu Comfort 2.5kW Split System Installation

Client Overview

The homeowners of this two-storey residence in Kahibah, NSW contacted Valley Air Conditioning to improve comfort in their upstairs bedroom. During warmer months, heat naturally rises through the home, making the upper level significantly warmer than the rest of the house. This resulted in uncomfortable sleeping conditions and inconsistent temperatures, particularly during summer evenings.

The clients were seeking a solution that would:

• Provide effective cooling for the upstairs bedroom
• Operate quietly for uninterrupted sleep
• Be energy efficient to minimise running costs
• Be installed neatly and professionally with minimal disruption

After an initial consultation and site inspection, Valley Air Conditioning recommended a 2.5kW Fujitsu Comfort ASTH09KNCA split system air conditioner using R32 refrigerant as the ideal solution.

Site Assessment and System Recommendation

Valley Air Conditioning began the project with a thorough on-site assessment. The upstairs bedroom was of moderate size but experienced elevated heat load due to its location, limited cross-ventilation, and direct afternoon sun exposure. The team also assessed ceiling height, insulation levels, window placement, and wall access for pipework and drainage.

Electrical capacity and outdoor unit placement options were reviewed to ensure compliance with Australian Standards and to achieve the cleanest possible installation finish.

Based on the room size and usage patterns, a 2.5kW system was identified as the correct capacity. This ensured the unit would cool efficiently without being oversized, which can lead to unnecessary power consumption and reduced dehumidification performance.

The Fujitsu Comfort ASTH09KNCA was selected for its:

• Reliable cooling performance for bedrooms and smaller spaces
• Inverter technology for efficient temperature control
• Quiet indoor operation suitable for sleeping areas
• Use of R32 refrigerant, which offers improved energy efficiency and a lower environmental impact compared to older refrigerants

Air Conditioner Installation Planning

As the installation was located on the upper level of a two-storey home, careful planning was essential. Valley Air Conditioning coordinated the installation to minimise disruption and ensure safe access to both the indoor and outdoor installation points.

Protective coverings were laid throughout access areas, and the homeowners were briefed on the installation process and timeline before commencement.

Air Conditioner Installation Process

Indoor Unit Installation

The indoor unit was installed high on an internal wall within the upstairs bedroom to maximise airflow and ensure even cooling throughout the space. The position was selected to avoid direct airflow over the bed while still delivering consistent temperature control.

The sleek design of the Fujitsu Comfort unit allowed it to blend seamlessly with the bedroom’s interior, maintaining the room’s aesthetic appeal.

Outdoor Unit Installation

The outdoor condenser was installed externally at ground level, mounted securely with vibration-reducing feet. This placement allowed for:

• Adequate airflow and ventilation
• Reduced noise transfer into the bedroom
• Easy access for future servicing and maintenance

Copper refrigerant pipework, insulated to prevent condensation and energy loss, was neatly routed between the indoor and outdoor units. Condensate drainage was installed to ensure effective moisture removal and long-term system reliability.

Electrical, Testing & Commissioning

All electrical connections were completed by qualified technicians, including isolation switches and safety protections in accordance with Australian Standards.

Once installed, the system underwent comprehensive testing and commissioning:

• Refrigerant pressure and pipe integrity checks
• Verification of correct refrigerant charge
• Thermostat calibration and airflow testing
• Confirmation of quiet operation across all fan speeds

The system was run under load to ensure it delivered the expected cooling performance in the upstairs bedroom environment.

Client Handover & Education

Following commissioning, the Valley Air Conditioning team provided a full handover to the homeowners. This included:

• Demonstrating remote control functions and operating modes
• Explaining timer and energy-saving settings
• Providing guidance on filter cleaning and basic maintenance
• Answering questions regarding efficient system use

This ensured the homeowners felt confident operating the system from day one.

Outcome and Client Satisfaction

The installation delivered an immediate improvement in comfort. The upstairs bedroom now maintains a stable, comfortable temperature even during hot summer nights, significantly improving sleep quality.

Key benefits achieved included:

• Fast and efficient cooling tailored to the room size
• Whisper-quiet operation ideal for nighttime use
• Improved energy efficiency thanks to inverter technology and R32 refrigerant
• A clean, professional installation with minimal visual impact

The homeowners praised Valley Air Conditioning for their professionalism, clear communication, and attention to detail throughout the project.

Conclusion

This Kahibah installation highlights the importance of correct system sizing, modern refrigerant technology, and experienced installation, particularly in two-storey homes where heat load can vary significantly between levels. By supplying and installing a 2.5kW Fujitsu Comfort ASTH09KNCA split system, Valley Air Conditioning delivered a reliable, efficient, and environmentally conscious cooling solution that transformed the comfort of this upstairs bedroom.
