Daikin is a well-known global HVAC manufacturer offering a wide range of air conditioning solutions, including split systems, ductless mini-splits, and central air conditioning units. They are known for their energy-efficient technology and reliability.
How do you prevent future issues?
- Clean Your Condenser: Regularly cleaning the condenser coil enhances AC performance by preventing heat from getting trapped by dust and grime, which can result in reduced cooling efficiency and higher energy consumption, leading to increased electricity bills.
- Clean Your Filter: Like the condenser, maintaining clean AC filters is essential for better air quality and improved air circulation. Dirty filters can harbour dust, grime, and bacteria, potentially leading to mould growth that may compromise your family's health.
- Responsibly Control AC Usage: Minimise wear and tear on your AC by using it judiciously. Consider using Mitsubishi's ducted air conditioning, which allows you to schedule automatic on/off times.
- Schedule Regular Servicing: Routine maintenance and servicing are vital to sustaining the efficiency and proper functioning of your AC system.
- Maintain Your Remote Control: Ensure your AC remote control, whether for a Mitsubishi split system or Mitsubishi Heavy Industries, remains in good condition for your AC to operate effectively.
- Replace Air Conditioning Vents: Replacing air conditioning vents helps enhance air quality, overall comfort, and the efficiency of your AC in your home.

How do you know when it’s time to get a new air conditioner instead?
You can typically tell it's time to replace your current air conditioner when it has exceeded 10 years of service. Older units often begin to experience more frequent issues, such as duct leaks or malfunctioning fans, and these problems tend to occur at inconvenient times. Replacing an ageing air conditioner can help improve efficiency, reduce the frequency of breakdowns, and ensure a more reliable and energy-efficient cooling system for your home.
Conclusion
Maintaining and troubleshooting your air conditioning system is essential for optimal performance and longevity. Regular cleaning of the condenser and filters, responsible usage, scheduling routine servicing, and keeping the remote control in good condition are crucial steps to ensure your AC functions effectively. Additionally, being aware of fault codes and understanding the symbols on your unit can aid in quick issue identification.
When your air conditioner is more than a decade old and exhibits frequent breakdowns, it may be time to consider replacing it for improved efficiency and reliability. Proper care and maintenance of your air conditioning system can lead to a more comfortable and healthy indoor environment.
