Air Conditioning and Air Handling Unit Maintenance Plans with Emergency Services


Efficient air conditioning maintenance and repair significantly reduce the risk of breakdowns and operational costs. Properly maintained equipment not only performs better but also lasts longer, minimising the chance of premature malfunction. This principle is especially true for your air conditioning and air handling units.
Our AirCare maintenance packages provide scheduled service visits throughout the year, ensuring your systems operate efficiently. These visits help maintain excellent air quality and compliance with f-gas regulations, enhancing your units' longevity and performance.
Benefit from our comprehensive air conditioning maintenance service packages, which can include optional UV air sanitisation and AirCare disinfectant micro-fumigation. Investing in regular maintenance safeguards your HVAC investments and supports your financial goals by protecting your bottom line.

There is no exception when it comes to your HVAC system and we recommend a 6-monthly service as a minimum to ensure that systems are operating correctly, efficiently and safely.

It also means that we can quickly identify any equipment that is malfunctioning and offer a repair, which could potentially avert a significant capital expense.
As mentioned above, our servicing package also ensures that your manufacturer’s warranty is upheld, preventing you from needlessly being exposed to the costs of equipment failure.




Signs Your Ventilation System Service Is Due?
Recognising the early signs of ventilation issues can help prevent costly repairs and system breakdowns. Here are some key indicators that your ventilation system service is due.
- Reduced Cooling Performance – If your AC is struggling to cool your space effectively, it could be due to clogged filters, low refrigerant levels, or a failing compressor. Regular maintenance ensures optimal cooling efficiency.
- Unusual Noises or Odors – Grinding, rattling, or squealing noises may indicate loose or worn-out components, while musty or burning smells can signal mold growth or electrical issues. Professional servicing can resolve these problems before they worsen.
- Increased Energy Bills – A sudden spike in energy costs often means your AC is working harder than necessary due to inefficiencies. Dirty coils, blocked airflow, or malfunctioning parts can all contribute to excessive energy consumption.
- Weak Airflow or Inconsistent Temperatures – Poor airflow or uneven cooling in different areas of your home or office may suggest issues with the blower motor, ductwork, or air filters. Routine maintenance ensures balanced air distribution for consistent comfort.
