Commercial Air Conditioning in Mackay | McGuire Air & Refrigeration

What’s the best type of air conditioning for a commercial building?
The best system depends on the size and layout of the building, usage patterns and the number of zones needed. Ducted systems are ideal for larger offices or multi-room setups, while VRV or cassette units work well for open-plan spaces or where individual control is needed. It's important to consider energy ratings, noise levels, and long-term servicing requirements when choosing the right system.
How often should a commercial air conditioner be serviced?
Most commercial air conditioning systems should be serviced at least twice a year, although this can vary based on usage, system type and the environment. Regular servicing involves cleaning filters, inspecting electrical connections, testing airflow, and checking for refrigerant leaks. Scheduled maintenance improves performance, extends equipment life and helps businesses avoid unexpected breakdowns or costly repairs.
Are commercial systems more expensive to run than residential ones?
Generally, yes—commercial systems are larger and operate for longer hours, so running costs tend to be higher. However, properly designed systems with smart zoning, inverter technology and routine maintenance can significantly improve efficiency. Businesses can also take advantage of off-peak settings and programmable controls to reduce energy use without compromising comfort.
