Mitsubishi Ductless mini-split: 6 Cleaning Tips

It’s time for spring cleaning!

Ductless mini-split systems require annual maintenance to ensure their components keep you warm and cool all year round. As a Mitsubishi Diamond Elite partner, our trained technicians clean your system just as the manufacturer recommends.

Mitsubishi Ductless spring cleaning checklist:

  1. Airflow: Air-source heat pumps require free airflow to the indoor and outdoor heat-exchanger coils. The air filter inside the indoor air-handling unit (AHU) is removed and cleaned.
  2. Clean coils: Coils are deep-cleaned to remove debris and contaminants, and to help prevent mold and mildew growth. Clean coils are important for efficient heating and cooling.
  3. Refrigerant: The refrigerant lines, coils, and flare connections are inspected for leakage.
  4. Drainage: Clear drainage must be maintained to prevent water leaks and damage. Drain lines are flushed and treated to clear and inhibit algae and mold growth.
  5. Electrical contacts: Wiring and contacts are inspected for wear. Poor wiring and electronics can cause ice to form on the outdoor coil (heating months) and the indoor coil (cooling months).
  6. Compression: High-performance ductless mini splits utilize digital inverter-driven compressors, electronic expansion valves (EEV), and sophisticated sensors to prepare, regulate and monitor super-heating of high-efficiency refrigerant. Our trained and skilled technicians will inspect and test these components.
