Inspecting and Repairing a Split System Air Conditioner
Case Study: Climate Air Solutions repairs a split system air conditioner in Balberra, QLD
Climate Air Solutions was recently called to inspect and repair a split system air conditioner at a residential property in Balberra, Queensland. The homeowner had concerns about the performance and overall condition of their older cooling-only unit, which operates using R22 refrigerant and is a non-inverter system. Given the age of the system and the phase-out of R22 refrigerant, the client wanted a thorough assessment to determine whether repairs were worthwhile or if replacement should be considered.
Upon arrival, the Climate Air Solutions technician began with a comprehensive system inspection, starting with the outdoor condensing unit. Initial diagnostic checks included measuring operating pressures and amp draws to assess the system’s performance under load. Encouragingly, both readings were found to be within normal operating ranges, indicating that the compressor and refrigeration cycle were functioning as expected.
During the visual inspection of the condensing unit, an unusual issue was discovered—several dead frogs were found inside the wiring compartment. While this can sometimes lead to electrical faults or short circuits, in this case, no damage had occurred. The technician noted that because the system is a non-inverter model, it does not contain sensitive printed circuit boards (PCBs) that are more vulnerable to such issues. The frogs were safely removed, and all wiring was checked to ensure there were no hidden faults or deterioration. Fortunately, all components were intact and operational.
Further testing focused on the electrical components critical to the system’s operation. The compressor’s run and start capacitors were tested and found to be within manufacturer specifications. Similarly, the outdoor fan motor capacitor was inspected and confirmed to be functioning correctly. These results reinforced the initial findings that the system was mechanically and electrically sound.
The technician also assessed the overall condition of the outdoor unit. While there were minor signs of surface corrosion, this was considered typical for a unit of its age and exposure to the elements in a Queensland climate. Importantly, the compressor itself showed no signs of corrosion or wear that would indicate imminent failure. This is a key factor, as compressor replacement can often be cost-prohibitive in older systems.
One issue identified during the inspection was the deterioration of the pipe lagging on the exposed refrigerant lines outside the home. The insulation had worn away over time due to weather exposure. While this does not significantly impact the system’s performance in the short term, it can reduce energy efficiency and lead to minor thermal losses. The technician advised that replacing the lagging would be a simple and cost-effective way to improve efficiency and protect the pipework moving forward.
Attention then shifted to the indoor unit. A visual and operational inspection revealed a broken louvre on one side of the unit. Although the louvre still opens during operation, it does not fully close when the system is turned off. Due to the age of the unit, sourcing a replacement part may be difficult or impossible. However, the issue is largely cosmetic and does not significantly affect airflow or cooling performance.
The indoor coil was also inspected and found to be slightly dirty, which is consistent with normal wear and tear over time. The technician recommended a routine clean to maintain optimal airflow and efficiency, although it was not deemed an urgent issue. Additionally, the indoor unit’s fascia had yellowed from its original white colour, a common occurrence in older systems due to prolonged exposure to UV light and environmental factors.
After completing the full inspection and testing process, Climate Air Solutions concluded that the air conditioning system was generally in good working condition for its age. No major faults were identified, and the core components—including the compressor, capacitors, and electrical systems—were all operating within acceptable parameters.
The only issues noted were minor: the worn pipe lagging and the partially broken louvre. Both were classified as non-critical and largely cosmetic, with minimal impact on the system’s overall performance. The technician provided the homeowner with honest, practical advice—while the unit is still functioning well, its age and use of R22 refrigerant mean that future repairs could become more challenging and costly.
In summary, this case highlights the importance of regular inspections and honest assessments, especially for older air conditioning systems. Climate Air Solutions delivered a thorough and professional service, identifying potential concerns while reassuring the homeowner that their system remains reliable for the time being. With a few minor maintenance actions, the unit can continue to provide effective cooling, giving the homeowner time to plan for an eventual upgrade when necessary.
