Taking care of your heating, cooling, and ventilation system is an essential part of home ownership. Ductless mini-split systems are some of the most popular systems on the market, and if you're one of the many who love their ductless system, maintaining it is critical to ensure it is functioning optimally and will last for years to come. You can use this guide to guarantee you are taking the necessary steps to keep your ductless mini-split humming.

Maintenance is Important

  • Well-maintained systems last longer.
  • Dirty filters and neglected components can have a negative impact on your home’s indoor air quality.
  • A service technician can catch minor issues before they become major ones.
  • Regular maintenance helps detect potential safety hazards like gas leaks, carbon monoxide leaks, or electrical issues that can threaten your safety.

  • Systems that run optimally help reduce greenhouse gas emissions and overall environmental impact.

How to Maintain Your Ductless Mini-Split

Schedule Regular Maintenance Appointments

There are some things better left to the professionals. You can most certainly do some small tasks yourself, but a routine visit from a trained HVAC technician will help ensure you don't miss anything. At the very least, your system should be serviced once a year.

Seasonal Checks

Giving your outdoor unit the once-over before each season can help your compressor stay clean and clear of unwanted leaves and other yard debris. You can also make sure there are no animal nests or other obstructions that can increase the system’s energy consumption. This proactive approach ensures your mini-split system is ready to handle the upcoming weather conditions effectively.

Filter Replacement

The filters in your ductless mini-split system prevent dust, dirt, and other particles from circulating through the air.

The filters in your ductless mini-split system prevent dust, dirt, and other particles from circulating through the air. Over time, these filters can become clogged, reducing the system's efficiency, and causing strain on the unit. Check the user manual or ask your technician how often your filter needs replacing. Most filters need to be changed at least once every three months. However, higher-grade filters that sift even the smallest impurities out of the air should be replaced more frequently. You also may need to change your filter more often if you notice dust, pollen, or pet fur settling on top of surfaces in your home.

Test the Thermostat and Controls

For ductless mini-splits, the indoor air handler is also the thermostat and control center. Therefore, you should keep an eye on them to ensure they are working correctly and replace the batteries in your remote as needed to avoid any operational issues. Additionally, do not change the settings dramatically on your thermostat. Small incremental temperature changes are ideal to reduce wear and tear on the handler.

Ductless mini-split regular maintenance ensures your system operates to its best capacity. By following these best practices, you can prolong its lifespan, improve efficiency, and enjoy a comfortable indoor environment year-round.
