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

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

Regular inspections and checks on operating performance are easily completed by our fully trained Daikin and Fujitsu service technicians, generally without affecting the operation of the system or inconveniencing your family’s normal activities. Such inspections are an invaluable tool to highlight any matters requiring further attention, or to prevent costly unplanned repairs or frustration when major repairs become necessary.

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, checking both condenser and evaporator coils, fan blowers, filters and condensate trays to clean and remove any dirt or dust build-up that may prevent efficient operation.

We also recommend an Alliance Climate Control Eco-clean service every two years to clean and service the finned coils incorporating a microbial treatment of the coil to eradicate any dust, dirt or dangerous pathogens for prolonged periods.

We will also check the ducting and air entry grilles to each room to make sure they are clean and sealed properly ensuring you get the most benefit from your Split or Multi-split air conditioning system.

Why are Split and Multi-Split Air Conditioning System Services necessary?

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

Regular service inspections will check:

  • Temperature sensing and operation of the inverter compressor and other critical components ensuring consistent and desired air delivery temperature.
  • Build-up of dust or pollens in the fan, coil or filters 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 further emphasised if air flow through the evaporator coil is poor or restricted causing extra load on the compressor.
  • Dust accumulation on fans or condenser coil may reduce the heat dissipation characteristics of the condenser coil, in turn putting extra load on the compressor when the condensing process is compromised.

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

Alliance Climate Control will help make sure your Split and Multi-split air conditioner system continues to operate consistently with optimum efficiency.

At regularly scheduled services recommended at 12 month intervals, 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 properly.

We can also check refrigerant gas pressure at various points within the circuit to verify optimal performance of the compressor, evaporator and condensation coils.

Additionally, we can also check the outlet temperature at each room entry grille 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 at optimum efficiency, providing you with maximum comfort. We also recommend an Alliance Climate Control Eco-Clean service every two years to make sure the finned evaporator coil remains clean and clear from bacteria.
