Ductless Split Cleaning
If someone in your household suffers from allergies or unexplained symptoms or illnesses and if your ductless split is contaminated with deposits of dust or mold or have a musty smell then that is a sign that your ductless split system should be cleaned.
When your system is a few years old, you may start to smell some…unpleasant odors. This is a sign that you should call a pro to clean the coils on your outdoor and indoor units. Especially when your mini split is in AC mode, moisture collects in these coils and can start to harbor mold or mildew. Make sure to have your HVAC professional check these coils to avoid this problem.
