Ensuring the Longevity of Your Split System AC: Key Maintenance Tips

Posted on: 4 June 2024

When it comes to keeping your home cool and comfortable, a split system air conditioning unit can be a game-changer. These systems offer efficient cooling without the need for extensive ductwork. However, like any other appliance, split system AC units require proper maintenance to ensure they function effectively and last for years to come.

Regular Cleaning of Filters and Coils

One of the most crucial maintenance tasks for your split system AC is keeping the filters and coils clean. Over time, dirt, dust, and other debris can accumulate on the filters, reducing airflow and making your unit work harder to cool your home. Similarly, the evaporator and condenser coils can collect dirt, hindering heat transfer.

A clogged filter or dirty coils not only reduces the efficiency of your AC but can also lead to system breakdowns if left unchecked. By regularly cleaning or replacing filters and scheduling professional coil cleaning as needed, you can improve the performance of your unit and prevent costly repairs.

Checking Refrigerant Levels

Another essential aspect of split system AC maintenance is ensuring that the refrigerant levels are adequate. Low refrigerant levels can indicate a leak in the system, which not only affects cooling performance but can also damage other components. If you notice that your home is not cooling as effectively as before or hear hissing sounds from the unit, it may be time to have a professional check the refrigerant levels and address any leaks promptly.

Inspecting Ductwork and Insulation

While split system AC units do not rely on ductwork for air distribution like traditional central air systems, they still require proper insulation to maintain efficiency. Inspecting the insulation around refrigerant lines and ensuring there are no leaks or gaps can help prevent energy loss and keep your home cool without overworking the unit.

Additionally, if your split system AC is part of a larger HVAC system that includes ducts for heating or ventilation, it is essential to have these ducts inspected regularly for leaks or blockages. Properly sealed ductwork ensures that cooled air reaches all areas of your home efficiently.

Maintaining Outdoor Unit Components

The outdoor unit of your split system AC is exposed to the elements year-round, making it susceptible to debris buildup, vegetation growth, and weather damage. Regularly inspecting the outdoor unit for obstructions around the fan, clearing away leaves or branches that could impede airflow, and ensuring that the unit remains level can all contribute to its longevity and performance.

Professional Maintenance Checks

While there are several maintenance tasks homeowners can perform themselves to keep their split system AC in top condition, scheduling annual professional maintenance checks is highly recommended. HVAC contractors have the expertise and tools to inspect all components of your AC unit thoroughly, identify potential issues early on, and perform any necessary repairs or adjustments.

By staying proactive with regular maintenance tasks and seeking professional help when needed, homeowners can enjoy reliable cooling comfort from their split system AC units for years to come.
