What is Multi-Split Air Conditioning System Service and Repairs?

Regular service and repairs of Multi-split air conditioning systems are critical to make sure they continue to operate at peak efficiency.

Regular inspections and checks on operating performance are easily completed by Alliance service technicians, generally without affecting the operation of the system or inconveniencing those in the conditioned space. Such inspections are invaluable to highlight if further attention is needed, preventing costly unplanned repairs or frustration to the building’s occupants.

Alliance Climate Control inspections keep your system operating at peak performance all year round.

We will make sure the compressor and critical components of the system are operating correctly. We will also check each of the coils, fan blowers, filters and condensate trays to keep them clean and remove any dirt or dust build-up that may prevent efficient operation.

We will also check the ducting to each room to make sure it is clean and sealed properly ensuring you get the most benefit from your Multi-split air conditioning system.

Why are Multi-Split Air Conditioning System Service and Repairs necessary?

Multi-split air conditioning service and repairs, make sure your system is working at peak performance. Servicing should be scheduled at regular intervals, ensuring filtration mediums are free from dust or pollens that may prevent efficient cooling or even produce unpleasant odours, adversely affecting the comfort of occupants.

Regular service inspections and repairs will check for:

  • Incorrect temperature sensing and poor operation of critical components that may be the cause of inconsistent or ineffective air temperature delivery.
  • Build-up of dust or pollens in the fan, coil or filters within each indoor unit and poor sealing of room entry grilles allowing ingress of dust or conditioned air to escape.
  • Low level of refrigerant gas. This may be perceived by occupants as inferior cooling efficiency and result in selection of a lower temperature in turn causing further load on the compressor.
  • Dust accumulation on fans, fan coils or condenser coils, reducing the heat dissipation characteristics of each coil in the system.
  • Inaccurate thermal load sensing at each of the coils causing too much or too little circulation of refrigerant gas producing unnecessary load on the compressor and an increase in power consumption.

How can we help with Service and Repair of your Multi-Split Air Conditioning System?

We can help to make sure your Multi-split air conditioner system continues to operate with optimum efficiency.

At regularly scheduled services, we can check the operation of the indoor unit and room entry grilles to make sure all components are sealed properly and each unit working within its optimum range.

We can also check system pressure at various points within the circuit to verify optimal performance of the compressor and other components ensuring an optimum supply of refrigerant gas is supplied to each indoor unit.

Additionally, we can also check the outlet temperature of each unit against calibrated thermometers to ensure the desired air temperature is being delivered.

Each of these checks when completed on an annual basis will ensure your system is working at optimum efficiency, providing you with maximum comfort.
