For commercial air conditioning systems, we recommend that systems are serviced every 3-6 months at a minimum. Carrying out frequent servicing reduces the chances of mould / dust build-up, prevents breakdowns such as water leaks, extends the life of equipment and reduces energy bills. Programmed preventative maintenance ensures systems are clean and operating optimally.

If you notice any issues such as reduced cooling efficiency or strange noises, it's best to contact a professional HVAC technician. They can diagnose the problem and perform any necessary repairs to restore the system's functionality.

There are a few ways to improve energy efficiency. Firstly, use programmable thermostats to set temperature schedules based on occupancy. Secondly, ensure proper insulation in your building to prevent cool air from escaping. Thirdly, regular maintenance, including cleaning or replacing filters, can improve efficiency. Lastly, it is worth considering whether your system is at the end of its economic life cycle, where upgrading the system would provide far greater system efficiency.

Commercial air conditioning systems have an estimated life cycle of 15-20 years (wall hung split systems’ estimated life cycle is between 7-10 years). If a system is at least several years old and costly repairs are arising, it is always best to compare these repair costs to that of a new system.

To improve air quality, regular maintenance is crucial. Clean and replace filters regularly to remove dust, allergens, and pollutants from circulating in the air. Additionally, review whether outside air is being introduced into the building (commonly done so via outside air duct into return air of split ducted systems). If no outside air is being provided, consider implementing a ventilation system that brings in fresh outdoor air and utilizes air purifiers or filters to eliminate contaminants. Regular duct cleaning can also help maintain good air quality by removing any accumulated dirt or debris.
