Why choose MAINair?

Maintain continuous, reliable operation

arrow icon

Implementing a programmed preventative maintenance plan makes good business sense for many reasons. The most obvious being the ability to identify impending mechanical or electrical faults long before they fail, eliminating potentially large repair bills and significant disruption.

An efficient and well-maintained system will result in lower operating costs, controlled health risks, and most importantly, tenants and occupants remain comfortable and happy.

Efficiency equals reduced cost

arrow icon

Part of our service procedure involves analysing the system for faults and maintenance issues that could impact on operational efficiency, particularly in extreme conditions. Maximising the efficiency of the system by controlling airflow and the operating temperatures of compressors and motors, can result in substantial cost savings over a period of time. This service is included in our comprehensive service plan, which we design exclusively for each system.

Service when you need it, 24/7

arrow icon

An around the clock breakdown service is available to all our service clients, 24 hours a day, 7 days a week. We understand the commercial implications of even a minor breakdown. Our no-compromise approach to service means we can generally have a technician on-site within an hour anywhere in the Adelaide CBD.

Controlling health risks

arrow icon

Every air-conditioning system is a network for complex mechanical and electrical components. They are made to last and are engineered to operate over extended and often extreme conditions. But without regular programmed maintenance, the life and reliability of any component within the system can be seriously compromised.
