Regular maintenance is essential to keep your split system air conditioner working efficiently and avoid unexpected breakdowns. Neglecting upkeep reduces performance, shortens lifespan, and increases energy bills. Knowing the warning signs and proper care can help save money and keep your Jindalee home comfortable.
Signs Your System Needs Attention
Your air conditioner might seem like it’s working fine, but there are some common signs that could mean it’s overdue for a maintenance service:
- Weaker airflow even on high settings
- Warm air is blowing when it should be cooling
- Unusual noises like buzzing, banging or squealing
- Musty or foul odours from the vents
- Rising electricity bills with no change in usage
- Visible dust or dirt is building up around the indoor unit
- Water leaking from the indoor system or pooling near the outdoor unit
These signs are your early warning that something’s off. Ignoring them could mean reduced cooling performance, poor air quality, or worse, expensive repairs.
Split System Maintenance
Keeping your split system in good shape doesn’t have to be complicated, but it does need consistency. A proper maintenance commonly involves:
Clean or Replace Filters
Filters trap dust, allergens and bacteria. When they’re dirty, airflow suffers, and the system works harder than it should. Clean or replace them every one to two months. During high-use periods like summer, monthly is best.
Coil and Fin Cleaning
Evaporator and condenser coils can collect dirt over time, reducing heat absorption and transfer. Dirty coils can also lead to ice buildup or strain on the compressor. Fin combs can straighten bent fins and improve airflow.
Drain Line Conditioning
If the condensate drain is blocked, moisture builds up and may leak into your home or cause mould. A professional can flush the drain to prevent these problems.
Refrigerant Levels
Low refrigerant can mean a leak, which affects cooling efficiency and can damage the compressor. It needs to be checked and topped up by a licensed technician only.
Clearing the Outdoor Unit
Leaves, dirt and debris around the outdoor unit can block airflow and overheat the system. Keep at least 60 centimetres of clear space around the unit and gently remove any build-up.
Test Heating and Cooling Functions
For reverse-cycle systems, it’s good practice to check both modes as the seasons change, making sure the unit switches over correctly and performs in all conditions.
Even when everything seems fine, hidden issues can be developing. It’s best to book a full service once a year, ideally before summer, to ensure your system is ready for the increased demand.
The Importance of Professional Servicing
While basic tasks like filter cleaning are simple enough, anything involving refrigerant, wiring or internal components should be left to the pros. DIY repairs can lead to damage, safety risks or void warranties.
