Preventative Care For Your Business

Preventative maintenance is one of the smartest investments a business can make. A well-maintained air conditioning system runs more efficiently, lasts longer, and is far less likely to break down when you need it most. At AJM Air Conditioning Centre, we offer tailored maintenance plans that keep your systems performing their best — whether you’re operating a single retail outlet or managing a multi-building commercial site.


From routine checks and filter cleaning to performance testing, electrical inspections, and coil maintenance, we follow detailed processes to identify potential issues before they become costly repairs. For large-scale contracts, such as our ongoing work with Southern Cross University, we carry out preventative maintenance to extend the life of critical systems and reduce energy waste. Our team also supports compliance reporting, helps with warranty tracking, and ensures your systems meet safety standards.


Downtime costs money — but with proactive care, you can avoid surprises and stay ahead of issues. To create a maintenance plan or request a one-off service, call (02) 6621 3381 today and talk to a team that knows commercial systems inside and out.

Frequently Asked Questions

  • How often should commercial air conditioning systems be serviced?

    Most commercial systems should be serviced quarterly, especially in high-usage environments such as retail spaces, offices, hospitality venues, and healthcare facilities. Quarterly servicing allows for filter cleaning, coil inspection, refrigerant level checks, and system testing to catch issues early. In lower-demand environments, bi-annual servicing may be sufficient, but regular maintenance is essential to ensure compliance, reduce running costs, and maintain indoor air quality.

  • Why is my commercial air conditioning system making loud noises or vibrations?

    Unusual noises or vibrations often point to mechanical issues like loose parts, worn-out fan bearings, or imbalanced components. In ducted systems, it could also relate to air pressure problems or debris inside the ducts. Ignoring these sounds can lead to serious system damage and even safety risks. It’s important to get the system inspected promptly by a qualified technician to prevent costly downtime or more extensive repairs.

  • Can commercial air con systems be repaired on the same day?

    Many issues can be resolved on the same day if the problem is straightforward and the required parts are available. Common same-day repairs include blocked filters, faulty thermostats, drainage issues, and minor electrical faults. For more complex repairs — such as compressor failures or refrigerant leaks — additional time may be needed to order parts or perform extensive testing. Choosing a local service provider with stocked vehicles improves your chances of same-day resolution.
