Maintaining Your Split AC: Cleaning Filters and Air Ducts Regularly

Proper maintenance of your split air conditioner is essential for its optimal performance, energy efficiency, and longevity. This includes regularly cleaning the filters and air ducts, as well as periodic professional servicing. In this article, we will discuss the importance of these maintenance tasks and how often you should perform them to keep your air conditioner running smoothly.

How Often Should I Clean My Split AC Filters?

The filters of your split air conditioner should be cleaned every 1 to 2 months, especially during peak usage seasons. If you use your AC frequently or live in a dusty environment, you may need to clean them more often. Regular cleaning helps maintain the efficiency of your air conditioner and improves air quality.

Electrospun nanofibers are used in the split AC filter to provide additional support for air purification. These nanofibers have been tested for their filtering ability at Nelson Labs, offering effective and cleaner air for your home. Changing the filter after every 1-2 months can provide the best results, especially if the filter is used continuously. Depending on the use, the filter is expected to last 300-500 hours if the air quality is good. For poor air quality, it is recommended to clean it weekly.

Air Conditioner Coils and Other Components

Along with the filters, other components of your split air conditioner require regular maintenance:

Coil Fins: These can become bent or damaged over time. Regular cleaning will help maintain their effectiveness and prevent air leakage. Condensate Drains: Clogged condensate drains can lead to water leakage and damage to your unit. Keep them clear and check for any blockages. Preparing for Winter: If you live in a cold climate, it's wise to prepare your split air conditioner for winter by cleaning it thoroughly and sealing any leaks to avoid ice buildup and compressor damage. Hiring a Professional: While regular cleaning is important, it's equally crucial to have a professional service your unit annually for optimal performance. A technician should check the following components:

What a Technician Should Check

Correct Amount of Refrigerant: Ensure the refrigerant level is appropriate and top up if necessary. Leak Detection: Use a leak detector to check for any leaks and repair them to maintain system efficiency. Refrigerant Management: Recover any refrigerant that must be evacuated from the system, instead of releasing it into the atmosphere. Central System Duct Sealing: Test for and seal duct leakage in central systems. Evaporator Coil Airflow: Measure the airflow through the evaporator coil. Control Sequence Verification: Ensure the electric control sequence is correct and that the heating system and cooling system cannot operate simultaneously. Cleaning and Tightening Electric Terminals: Clean and tighten connections, applying a non-conductive coating if necessary. Motor Oiling and Belt Inspection: Oil the motors and check the belts for tightness and wear. Thermostat Accuracy: Verify the accuracy of the thermostat.

Further Considerations for Air Ducts

As a household owner, you should take care of your AC ducts by cleaning them regularly. While there is no set time period to clean your air ducts, it is recommended by the NADCA (National Air Duct Cleaners Association) to clean them every three to five years. This is based on the growing awareness of the importance of clean indoor air quality and health-conscious practices.

If you find the need to clean your air ducts more than once a year, there might be a problem with the system that is allowing dirt to enter the components. In such cases, it is advised to call in HVAC experts for a professional inspection and cleaning.

Regular maintenance is crucial for your split air conditioner to function efficiently and provide a comfortable living environment. By following these guidelines, you can ensure your air conditioner remains in top condition, save energy, and extend its lifespan.
