How does split system air conditioning work?

Split system air conditioners operate by dividing the cooling process between two units. The outdoor unit contains the condenser, while the indoor unit houses the fan coil. During operation, the fan coil draws warm indoor air, passing it over cold coils filled with refrigerant. This process removes heat and humidity, returning cool, comfortable air to your living space. In the winter, the system can reverse the process, efficiently warming your home. Split system air conditioners offer versatile climate control, ideal for Australia’s varying weather conditions.

Signs your split system air conditioner needs attention

Recognizing the signs that your air conditioner requires attention is vital to maintaining a comfortable and efficient indoor environment. Keep an eye (and ear) out for these warning signals, including strange noises, unusual smells, reduced airflow, water leakage, and the presence of mould. Addressing these issues promptly through regular maintenance and professional servicing can save you from costly repairs and ensure your split system operates at its best.

Strange noises

One of the most noticeable signs that your split system air conditioner requires attention is strange noises. If you start hearing rattling, buzzing, or clanking sounds coming from your unit, it warrants some attention. These sounds could indicate various issues like loose components, a malfunctioning fan, or debris trapped in the system. Ignoring these noises may lead to more significant problems down the road.

Unusual smells

Unusual odours emanating from your split system should not be ignored. Foul or musty smells might suggest mould growth inside the unit or dirty filters. On the other hand, a burning odour could indicate electrical issues or overheating. Regular maintenance and cleaning can help prevent this ensure your system operates efficiently.

Reduced airflow

When you notice reduced airflow from your split system, it’s a clear sign that attention is needed. Poor airflow can be caused by clogged filters, blocked ducts, or a malfunctioning fan. Reduced airflow not only makes your system less efficient but also affects indoor air quality. Proper maintenance and filter replacement can restore optimal airflow.

Water leakage

Water leakage around your split system is a red flag that demands immediate attention. This could be due to a blocked drain line, a refrigerant leak, or a malfunctioning condensate pump. Ignoring water leakage can lead to costly damage to your unit and your property. Addressing this issue promptly can prevent further complications.


The presence of mould in or around your split system is a serious concern. Mould not only affects indoor air quality but can also pose health risks. If you notice mould growth, it’s crucial to address the problem promptly. Regular cleaning and maintenance can help prevent mould from taking hold in your system.
