Air Conditioning Maintenance

Efficient and effective functioning of commercial air conditioning and mechanical ventilation systems is based on how well units are maintained, with faulty operation highlighted when summer scorches in Australia.

Keeping your air conditioning unit properly maintained is recommended for a variety of reasons, the most important including:

  • Providing better indoor air quality
  • Lowering electricity bills
  • Avoiding costly future air conditioner repairs and replacement.

To ensure the efficiency of your air conditioner, routine maintenance should include cleaning internal workings such as coils, drains and fins, and cleaning and replacing filters.

Dirty or clogged filters will block normal airflow and significantly reduce a systems efficiency. Dust and mould within units can lead to health issues and are a recipe for chronic illness, especially with existing conditions such as asthma or allergies.

A professional service technician will check the accuracy of the controls which is essential to maintaining year-round comfort in your premises. They will inspect electric terminals, ducts, refrigerant charge, check airflow through the evaporator coil and clean and tighten connections.

It is advisable to enter into a scheduled service agreement to provide regular preventative services at least four times a year. However, consideration should be given to the type of business you conduct, how old the system is, and the history of the unit itself. The environment is another contributing factor, with properties in dusty and damp locations potentially requiring more frequent attention, especially if the air conditioner is in constant use.

Neglecting maintenance will result in a steady decline in performance and mechanical integrity, while regular air conditioning services will help the unit to consistently operate at maximum capacity, will improve energy efficiency and running costs, and will save money by limiting the need for costly repairs and replacements.

It is mandatory under various Workplace Health and Safety Regulations to maintain commercial air conditioning installations on a regular basis. L G Fisher staff will inspect your equipment, recommend the frequency and scope of work required and provide a competitive quote to carry out the work.

Mechanical Ventilation Maintenance

Many commercial or multi-unit residential buildings rely on Mechanical Ventilation systems for the buildings to remain habitable and safe to occupy.

These include “Mechanical Exhaust Ventilation” for internal bathrooms and toilets and enclosed or underground car parks. Multi-story buildings often have “Stair Pressurisation” systems for fire and smoke control within stairwell escape routes.

All these Mechanical Ventilation systems require regular inspections and maintenance to remain compliant and maintain safe occupation of the buildings.
