Split System Air Conditioner Installation Brookvale NSW

Case Study: Supplying and Installing a 7.1kW Daikin Cora Split System in Brookvale, NSW

Overview

Platinum AC was engaged by a homeowner in Brookvale, NSW to supply and install a high-performance split system air conditioner in the master bedroom of their home. With summer temperatures rising and humid coastal conditions common across Sydney’s Northern Beaches, the client wanted a reliable, quiet, and energy-efficient solution that could deliver year-round comfort.

After assessing the room size, insulation, layout, and the household’s comfort preferences, Platinum AC recommended and installed a 7.1kW Daikin Cora split system reverse cycle air conditioner. The system was paired with a backlit wireless remote controller, providing intuitive operation and added convenience, especially for nighttime use in the bedroom.

The result was a clean, professional installation and a significant improvement in comfort, temperature control, and indoor air quality.

Client Requirements

The homeowner had several key requirements for the new air conditioning system:

• A unit powerful enough to comfortably heat and cool the master bedroom
• Quiet operation suitable for sleeping
• A modern, efficient reverse cycle system for both summer and winter
• A reliable brand with strong warranty support
• A controller that was easy to use at night and simple for all family members
• A tidy installation with minimal disruption to the home

The client also wanted the system positioned carefully so that airflow would be effective without blowing directly onto the bed, which is a common comfort concern in bedroom installations.

Site Assessment and System Recommendation

Platinum AC began the project with an on-site consultation to assess the master bedroom and identify the best installation approach.

The assessment included:

• Measuring the room size and ceiling height
• Reviewing window placement and sun exposure
• Considering insulation levels and likely heat load
• Identifying the most practical wall position for the indoor unit
• Selecting a location for the outdoor condenser that balanced airflow, noise control, and service access

After reviewing the conditions, Platinum AC recommended the Daikin Cora 7.1kW split system, a premium residential model known for its strong performance, energy efficiency, and quiet operation.

This system was particularly suitable for Brookvale conditions because it provides:

• Powerful cooling for warm coastal days
• Efficient heating during winter evenings
• Stable temperature control without harsh airflow
• Trusted reliability from one of Australia’s leading air conditioning manufacturers

Why the Daikin Cora Was the Right Choice

The Daikin Cora range is widely selected for bedrooms and living areas because it offers a balance of comfort, performance, and ease of use. For this installation, the 7.1kW capacity ensured the system could quickly reach the target temperature and maintain it consistently, even during extreme heat or cold.

The homeowner also valued the unit’s modern design, which suited the interior of the master bedroom and delivered a clean, unobtrusive look once installed.

Reverse cycle capability was another key advantage. Rather than needing separate heating and cooling solutions, the couple now had one system that could be used year-round, helping reduce energy consumption and simplifying the home’s climate control.

Split System Air Conditioner Installation Process

Once the system and layout were confirmed, Platinum AC scheduled the split system air conditioner installation at a time that suited the homeowner. The team arrived on-site with all required equipment and followed a structured process to ensure quality workmanship and a tidy finish.

The installation included:

1. Indoor Unit Placement

The indoor unit was mounted in the master bedroom in a position that provided strong airflow coverage across the room while avoiding direct airflow onto the bed. This ensured comfort without the dryness or discomfort that can occur when air blows directly onto sleepers.

2. Outdoor Unit Installation

The outdoor condenser was installed in a suitable external location with:

• Good ventilation
• Minimal noise impact on bedroom windows
• Easy access for future servicing
• Stable mounting to reduce vibration

Platinum AC ensured the unit was securely mounted and level, supporting long-term performance and minimising operational noise.

3. Refrigerant Piping and Electrical Connections

The installation required careful routing of pipework and cabling to ensure the final result was both functional and visually clean. Platinum AC completed all necessary refrigerant line connections, insulation, and electrical work in line with Australian standards and manufacturer requirements.

All penetrations through the wall were sealed properly to prevent drafts, moisture ingress, or pest access.

4. System Commissioning

Once installed, the system was fully commissioned, including:

• Vacuum testing and pressure checks
• Confirming refrigerant integrity
• Power testing and electrical safety checks
• Testing heating and cooling performance
• Confirming correct airflow and temperature response

This step ensured the system was operating exactly as intended from day one.

Backlit Wireless Remote Controller: A Practical Upgrade

A standout feature of this installation was the inclusion of a backlit wireless remote controller. While this may seem like a small detail, it made a big difference for the homeowner.

In a bedroom setting, a backlit controller provides:

• Easy visibility at night without turning on lights
• Faster access to temperature and fan controls
• Better usability for all household members
• A more premium user experience

Platinum AC took the time to demonstrate the remote’s key features, including:

• Temperature adjustment
• Fan speed control
• Quiet mode settings
• Timer functions for overnight comfort
• Heating and cooling mode switching

This ensured the homeowner felt confident operating the system and could immediately enjoy the benefits.

The Result

Following installation, the homeowner reported an immediate improvement in comfort. The Daikin Cora 7.1kW unit provided fast temperature control, maintaining a stable and comfortable environment throughout the day and night.

Key outcomes included:

• Reliable cooling during warm Brookvale afternoons
• Comfortable heating during cooler evenings
• Quiet operation ideal for uninterrupted sleep
• A neat, professional finish inside and outside the home
• Simple control with a user-friendly backlit remote

The client also appreciated Platinum AC’s clean work practices, clear communication, and professional handover.
