Air Conditioning Not Working Properly?
An air conditioning problem can range from a simple airflow or drainage issue to a more involved mechanical or refrigerant-related fault.
​
Rather than replacing parts without understanding the cause, we take a diagnostic approach to identify what is happening with your system.
​
We can investigate issues such as poor cooling, unusual noises, water around the indoor unit, unexpected shutdowns and other performance problems. Where the fault involves the refrigerant circuit, the work is handled within the appropriate qualification and certification requirements.
​
Our aim is simple: identify the problem, explain your options and provide a repair solution that is appropriate for the system.

Fault Assessment
We discuss the symptoms you have noticed and assess the air conditioning system to establish where the problem may be occurring.

Performance Checks
We check relevant system operation, controls, airflow, drainage and accessible components to help identify the cause of the problem.

Fault Diagnosis
Once the symptoms and system condition have been assessed, we explain the likely fault and whether further specialist investigation is required.

Component Repair or Replacement
Where appropriate, faulty or worn components can be repaired or replaced according to the system requirements and agreed scope.

Refrigerant-Related Issues
If the problem appears to involve refrigerant loss or another refrigerant-circuit issue, this is treated as a separate specialist requirement and handled by appropriately qualified personnel.

Testing & Final Checks
After agreed repair work, the system is checked to confirm that the relevant functions are operating correctly.
Common Air Conditioning Problems We Repair
01
Poor Cooling Performance
If your system runs but does not cool the room as expected, we can investigate the cause rather than assuming it is simply a refrigerant problem.
02
Air Conditioning Not Turning On
Control issues, electrical faults or component problems can prevent a system from starting. We can assess the system and identify the appropriate next step.
03
Water Leaking From the Indoor Unit
Blocked or restricted condensate drainage can cause water to collect around an indoor unit. We can inspect the drainage arrangement and investigate the cause.
04
Unusual Noises
Grinding, rattling, buzzing or other unusual sounds can indicate a mechanical or component issue that requires investigation.
05
Weak Airflow
Restricted filters, airflow problems or other system conditions can affect how effectively conditioned air reaches the room.
06
System Switching Off Unexpectedly
Repeated shutdowns can have several possible causes. We assess the system's operation to determine what requires attention.
