Case Study: Routine Service on 15.5 kW Reverse Cycle Ducted Air Conditioner, Balmoral, NSW

Overview

Valley Air Conditioning was engaged to perform a scheduled routine service on a homeowner’s 15.5 kW reverse-cycle ducted air conditioning system in Balmoral, NSW. The client had experienced reduced airflow and an increase in energy usage over recent months and wanted a thorough inspection and maintenance service to ensure optimal performance ahead of the summer season.

This case study highlights Valley Air Conditioning’s structured approach to maintenance, technical findings, troubleshooting, and recommendations that improved system efficiency, reliability, and occupant comfort.

Client Objectives

The homeowner’s primary objectives were to:

• Restore and maximise airflow throughout the dwelling.
• Improve overall system efficiency and reduce electricity costs.
• Identify any developing issues before they require costly repairs.
• Ensure the system is fully ready for increased seasonal use.

Valley Air Conditioning prioritised clear communication with the client, outlining what the service would include, what performance benchmarks to expect, and how any findings would be addressed.

Preparation and Arrival

Valley Air Conditioning scheduled the service visit at the homeowner’s convenience, arriving punctually with a fully stocked service vehicle carrying:

• Specialist diagnostic tools
• Coil cleaning solutions and fin combs
• Filters and micro-fibre cloths
• Refrigerant leak detection equipment
• High-pressure coil cleaner
• Safety and PPE equipment

Upon arrival, the technicians conducted a brief on-site walkthrough with the homeowner to discuss the service plan, confirm any recent symptoms, and prioritise concerns.

Inspection and Diagnostic Assessment

The service was conducted in a systematic sequence to ensure nothing was overlooked:

1. Airflow and Duct Inspection

Technicians first assessed airflow from each register. Several zones exhibited noticeably weaker airflow than others. A visual inspection of accessible ductwork showed:

• Minor dust accumulation near supply vents
• No significant blockages or damage
• Return air grille is moderately dusty

2. Filter Inspection and Cleaning

The system’s current filters were:

• Partially clogged with fine dust and pet hair
• Reducing air circulation and contributing to inefficiency

Valley Air Conditioning removed, cleaned, and reinstalled the filters. The homeowner was advised on filter replacement frequency based on lifestyle factors.

3. Outdoor Unit and Condenser Coil Examination

The outdoor condenser was cleared of surrounding debris, and the coil was inspected for:

• Dirt and grime build-up
• Corroded fins
• Evidence of pests or nest materials

The coil was moderately dirty, typical of systems near coastal environments like Balmoral, NSW.

4. Refrigerant Level Check and Leak Detection

Using precise gauges and electronic leak detectors, the team confirmed:

• Refrigerant levels were within an acceptable range
• No detectable refrigerant leaks

This ruled out the need for urgent repairs or recharge.

5. Electrical and Safety Checks

All electrical connections were tightened and tested, including:

• Capacitors and contactors
• Thermostat calibration
• Safety switches

All readings were within specification, and no unsafe conditions were found.

Maintenance Actions Taken

After the diagnostic phase, Valley Air Conditioning performed these maintenance tasks:

Filter Deep Clean

• High-efficiency electrostatic filters were deep-cleaned
• Removed trapped fine particulates
• Dried and reinstalled for immediate improved airflow

Coil Cleaning

• Both indoor evaporator and outdoor condenser coils were sprayed with environmentally safe coil cleaner
• Built-up dust, pollen, and accumulated grease were removed
• Coil fins were combed to ensure proper airflow

Drain Line Flush

• Drain pan and condensate line were flushed to remove algae build-up
• Prevented future water overflow and humidity issues

Performance Tuning

• Thermostat calibration adjusted for accurate temperature control
• Fan speeds optimised for comfort and efficiency
• System run-tested across cooling and heating modes

Results and Outcomes

After completing the routine service, the homeowner experienced several measurable benefits:

• Airflow increased significantly to all zones, eliminating weak spots
• System efficiency improved, with a noticeable reduction in run time
• Energy use reduced, contributing to lower electricity bills
• Noise levels lowered due to cleaner coils and balanced airflow
• Occupant comfort improved through more consistent temperature delivery

Moreover, Valley Air Conditioning provided the homeowner with a maintenance report summarising findings, actions taken, and the recommended next service interval based on usage patterns.
