What are Ceiling Mounted Cassette System Service and Repairs?

Regular service and repairs of Ceiling Mounted Cassette System is critical for continued operation and reliability and to maintain the designed operating efficiency.

Regular inspections and checks on operating performance are easily completed with little impact on operation of the system or those in the conditioned space. The ceiling mounted cassette system has been designed for ease of access to most critical system components.

Other major elements of the system are found in the outdoor system, providing equally simple access ensuring all inspection and testing procedures are completed promptly.

Although minimal downtime of the system is incurred whilst completing inspection and testing, such processes are an invaluable tool to forecast any faults that may cause unplanned equipment downtime, potentially costly repairs or frustration of occupants.

At Alliance Climate Control, we recommend regular service and repair inspections are conducted annually and we welcome scheduling a no obligation appointment in advance.

Why are Ceiling Mounted Cassette System Service and Repairs necessary?

Regularly scheduled Ceiling Mounted Cassette System service and repairs, make sure your system is working at peak performance ensuring critical components function correctly.

At Alliance Climate Control, we will check if filtration mediums are free from dust or pollens that may result in malfunction, unpleasant odours, adversely affecting the health of occupants.

Regular service inspections and repairs might highlight:


  • Incorrect temperature or motion sensing, or an unresponsive digital expansion valve which may cause delivery of an inconsistent or uncomfortable air temperature.
  • Build-up of dust or pollens in the fan, coil or filters within the ceiling mounted indoor unit or excessive dirt build up in the outdoor unit.
  • Low refrigerant gas levels. This may be perceived by occupants as inferior cooling efficiency and result in occupants selecting a lower temperature in turn causing further load on the compressor.
  • Inaccurate load sensing of the inverter compressor or direct current motor causing inefficient circulation of refrigerant gas.

How can we help with inspection and repair of your Ceiling Mounted Cassette System?

Alliance Climate Control can help to make sure your Ceiling Mounted Cassette System continues to operate with optimum efficiency.

At regularly scheduled services, recommended at not more than 12 month intervals, we can check the operation of all components of the indoor unit and sensory functions.

We can also check the system pressure and electrical current at various points within the circuit to verify optimal performance of critical components including the thermal expansion valve, compressor and electric motor.

Additionally, we also check the outlet temperature against our own calibrated thermometers to ensure the delivered air temperature and sensor units are operating correctly.

All these checks, when completed on an annual basis, ensure your system continues to operate at optimum efficiency for maximum comfort.
