Tips to Keep Your Ductless Mini-Split Running Efficiently

Ductless mini-split systems are an excellent solution for heating and cooling specific areas of your home. They are known for their energy efficiency and flexibility. However, like any HVAC system, they require regular maintenance to ensure optimal performance. At Savannah Air Factory, we want to help you keep your ductless mini-split running efficiently year-round. Here are some essential tips to maintain your system’s efficiency and longevity.

1. Regularly Clean the Filters

One of the simplest yet most important maintenance tasks is cleaning or replacing the air filters regularly. Dirty filters restrict airflow, forcing the system to work harder and reducing efficiency. Check your filters every month and clean or replace them as needed. This helps maintain good indoor air quality and ensures your system operates efficiently.

2. Keep the Outdoor Unit Clear

The outdoor unit of your ductless mini-split needs adequate airflow to function properly. Ensure the area around the unit is clear of debris, leaves, and any obstructions. Regularly inspect the outdoor unit and clean the fins and coils to prevent dirt buildup, which can hinder performance.

3. Inspect and Clean the Indoor Unit

Dust and dirt can accumulate on the indoor unit’s coils and blower wheel. Regularly wiping down the unit and cleaning the coils can prevent buildup that affects efficiency. Use a soft, damp cloth to clean the surface and ensure the unit remains free of dust and debris.

4. Schedule Professional Maintenance

While there are many tasks you can handle yourself, scheduling professional maintenance at least once a year is crucial. A trained technician can perform a comprehensive inspection, identify potential issues, and ensure all components are working correctly. Regular professional maintenance can extend the lifespan of your system and prevent costly repairs.

5. Monitor Refrigerant Levels

Refrigerant is essential for the cooling process. Low refrigerant levels can reduce efficiency and damage the compressor. If you notice a decrease in cooling performance, it may be due to a refrigerant leak. Contact a professional to check and refill the refrigerant if necessary.

6. Use the System Efficiently

To maximize efficiency, use the system’s programmable settings to control temperatures based on your schedule. Avoid setting the temperature too low in summer or too high in winter, as extreme settings can strain the system and increase energy consumption. Utilize the timer function to ensure the system runs only when needed.

7. Ensure Proper Installation

Proper installation is critical for the efficient operation of your ductless mini-split. Ensure the indoor and outdoor units are correctly installed and leveled, and that the refrigerant lines are insulated. Poor installation can lead to inefficiencies and potential system failures.


Maintaining your ductless mini-split system is key to ensuring it runs efficiently and lasts for years. Regular cleaning, professional maintenance, and smart usage can significantly enhance your system’s performance.
