What are Window Wall Mounted System Service and Repairs

Regular service and repairs of window wall mounted system are critical for continued reliability to maintain the designed operating efficiency of the unit.

Regular inspections and checks on operating performance are easily completed with little impact on the operation of the system or inconvenience to those in the conditioned space. In most cases, cleaning of the filters and finned coil fans can be checked at 6 week intervals by the home owner or occupant. However, more detailed inspections conducted by Alliance Climate Control technicians are recommended at least on an annual frequency.

Such inspections are an invaluable tool to highlight any faults and prevent unplanned equipment downtime which may result in costly repairs and frustration of occupants.

At Alliance Climate Control, we strongly recommend such regular service inspections at an annual frequency and advocate scheduling a no obligation appointment in advance.

Why are Window Wall Mounted System Service and Repairs necessary?

Regularly scheduled window wall mounted System service and repairs, make sure your system is working at peak performance ensuring critical components function correctly and filtration mediums are free from dust or pollens that may result in malfunction, unpleasant odours, adversely affect the health of occupants.

Regular service inspections and repairs might highlight:

  • Incorrect thermostat responses, or a digital expansion valve causing delivery of an inconsistent or ineffective air temperature.
  • Build-up of dust or pollens in the fan, coil or filters or excessive dirt build up around the condenser affecting air dissipation to the atmosphere.
  • Low refrigerant gas levels. 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.
