Repair and Service a Ducted Air Conditioner

Valley Air Conditioning Repairs and Services Three ActronAir Ducted Air Conditioners at Boolaroo Business

Valley Air Conditioning recently completed a detailed repair and full service of three ActronAir ducted air conditioning systems at a commercial premises in Boolaroo, New South Wales. The business had been experiencing ongoing issues with the air conditioning performance, particularly on warm days when the system was expected to provide essential cooling for the workspace and customers.

The management team reported that although the units were set to cool mode, the air being delivered through the vents was noticeably warm, creating discomfort for staff and impacting the overall working environment. Prompt action was required to resolve the issue and restore reliable cooling to the premises.

Initial Site Inspection and System Evaluation

When our technicians arrived on-site, we began with a comprehensive inspection of all three ActronAir ducted systems servicing different zones within the building. Each system had been correctly programmed and set to cool mode, yet none of them were delivering cold air. Instead, warm air was circulating throughout the office and public areas.

Given that all three systems were displaying the same fault, we suspected there may be a common issue affecting the sensor controls or system regulation.

We proceeded to test each system individually, starting with the control panels and thermostat settings to confirm they were properly configured. Once we ruled out user input errors, we turned our attention to the internal system components.

Identifying the Faulty Sensor

Through systematic fault-finding and performance monitoring, we discovered that the systems’ temperature sensors were not operating correctly. In ducted air conditioning systems, sensors play a critical role in monitoring ambient temperatures and signalling to the compressor when to switch on or off.

In this case, the faulty sensors were sending incorrect signals to the control boards, causing the systems to misinterpret the actual room temperatures. As a result, the compressors were not engaging correctly, and the systems continued to circulate air without actively cooling it.

This is a common but serious issue in commercial air conditioning where temperature accuracy is crucial to maintaining a comfortable environment, especially in customer-facing businesses or high-traffic spaces.

Repairing the Sensor Issue

Once we diagnosed the faulty sensors as the root cause, we quickly sourced genuine ActronAir replacement sensors compatible with each of the three ducted units. Replacing the sensors required careful disconnection of the faulty parts and precise installation of the new components to ensure accurate readings and communication with the control boards.

After fitting the new sensors, we recalibrated each system and thoroughly tested the temperature response to verify that the compressors were now cycling correctly and providing the expected cool air throughout the building.

Full System Service and Maintenance

In addition to the sensor repairs, we took the opportunity to perform a full service on all three ducted air conditioning systems. Servicing is essential to ensure that the systems operate efficiently, prevent future breakdowns, and maintain indoor air quality.

Our technicians:

• Cleaned the return air filters to restore unobstructed airflow.
  
• Inspected and cleaned the indoor fan coil units.
  
• Cleared and flushed the drainage lines to prevent water blockages or overflow.
  
• Checked all ductwork connections for leaks or damage.
  
• Cleaned the outdoor condenser coils to improve heat exchange efficiency.
  
• Verified refrigerant pressures to ensure they were within the correct operating range.
  
• Inspected all electrical connections, control boards, and system settings to ensure safe, reliable operation.

   

We also reviewed the zoning controls to confirm that each section of the business could independently manage temperature settings as needed.

Final Testing and System Handover

After completing the repairs and service, we conducted final performance tests on each system, running them through a full cooling cycle. The systems successfully reached the desired set temperatures, the airflow was cool and consistent, and the compressors were cycling correctly.

The management team at the Boolaroo business was very pleased with the result, noting that the indoor environment was quickly restored to a comfortable, productive space for both staff and visitors.

Preventative Maintenance Advice

We provided the business with detailed advice on ongoing air conditioning maintenance to help prevent future issues:

• Regularly clean or replace air filters to maintain airflow.
  
• Schedule annual professional servicing to check sensors, refrigerant levels, and system efficiency.
  
• Report any changes in system performance promptly to address minor faults before they develop into major repairs.
