How Do You Maintain a Split AC System?

Split system air conditioners are a go to choice for homeowners seeking efficient and targeted cooling. These systems are known for their flexibility and ease of installation. However, like any mechanical equipment, they require regular maintenance for optimal performance, energy efficiency, and longevity. Neglecting maintenance can lead to decreased cooling capacity, higher energy bills, and even system failure. So, how can you keep your split AC system in excellent condition? Let’s explore the details.

1. Regular Filter Cleaning or Replacement

The air filter of AC acts as the primary defence against dust, pollen, and other airborne particles. A dirty filter hinders airflow, which causes your system to work harder and use more energy. Additionally, it can result in the evaporator coil freezing.

• How often? It is best to clean or replace your air filters every month, especially during peak cooling seasons. If you have pets or allergies, you may need to do it more frequently.
• How to clean? Most filters are washable. Simply remove the filter, vacuum off any loose debris, and rinse it with mild soap and water. Make sure to let it dry completely before reinstalling. If your AC Air filter is not washable, replace it with a new one that is the same size and type.
• Types of Filters: Some systems use HEPA filters, which are highly effective at capturing small particles but may need to be replaced more often due to their higher efficiency.

2. Cleaning the Outdoor Unit

The outdoor unit  have the compressor, condenser coil, and fan. With time, it can accumulate leaves, dirt, and other debris that obstruct airflow and reduce efficiency.

• How often? Clear out the outdoor unit at least twice a year, preferably before the start of the cooling season and after the leaves have fallen in autumn.
• How to clean? Turn off the power to the unit at the breaker. Remove any visible debris, such as leaves and twigs. Use a garden hose with a gentle spray nozzle to clean the condenser fins from the inside out. Avoid using a high-pressure washer, as it can damage the delicate fins.
• Protecting the Unit: Consider installing a protective cover over the outdoor unit during the off-season to prevent debris accumulation.

3. Inspect and Clean the Indoor Unit

The indoor unit contains the evaporator coil and blower fan. These components can accumulate dust and mould, which can affect air quality and reduce cooling efficiency.

• How often? Inspect the indoor unit at least once a year. If you notice any signs of mould or excessive dust, clean it immediately.
• How to clean? Turn off the power to the unit. Carefully remove the front panel and inspect the evaporator coil. Use a soft brush or vacuum with a brush attachment to remove any dust. For stubborn mould, use a commercially available coil cleaner or a mixture of mild detergent and water. Be sure to follow the manufacturer’s instructions and rinse thoroughly.
• Preventing Mould: Regularly check for moisture buildup around the indoor unit and ensure proper drainage to prevent mould growth.

4. Check the Condensate Drain Line

The condensate drain line removes moisture from the evaporator coil. If it becomes clogged, water can back up into the unit and cause damage.

• How often? Check the drain line regularly, especially during periods of high humidity.
• How to clean? Locate the drain line outlet (usually outside the house) and use a wet/dry vacuum to suck out any clogs. You can also pour a cup of white vinegar down the drain line to help prevent future clogs.
• Preventing Clogs: Regularly inspect the drain line for any signs of blockage and ensure it’s properly sloped to facilitate water flow.

5. Professional Maintenance

While there are many maintenance tasks you can do yourself, it’s essential to schedule professional air conditioning servicing Adelaide at least once a year. A qualified technician can perform a thorough inspection of your system, check refrigerant levels, clean the coils, and identify any potential problems before they become major issues.

6. Monitor for Unusual Noises or Odours

Pay attention to any unusual noises or odours coming from your split AC system. These could be signs of a problem that needs to be addressed.

• Noises: Rattling, buzzing, or grinding noises could indicate a loose component, a failing motor, or a refrigerant leak.
• Odours: Musty or mouldy odours could indicate mould growth in the unit. A burning smell could indicate an electrical problem.
• Action Plan: If you notice any unusual noises or odours, turn off the system and contact a professional for assistance.
