Addressing Unusual Noises
Mini-split systems are designed to operate quietly. So, any unusual sounds indicate a problem that needs to be addressed. Identifying strange sounds is the first step in troubleshooting the issue. Some potential causes of unusual noises include:

- Airflow restriction
- Refrigerant leaks
If you hear a rattling or clanking noise, it could be due to loose parts or mounting brackets. Grinding or squealing sounds can indicate a problem with the fan blades. If there is a lack of airflow, it could be due to a dirty air filter or clogged ducts. Refrigerant leaks can cause hissing or bubbling sounds. Once you have identified the source of the noise, you can take steps to fix the issue. If you are not comfortable with troubleshooting and repairing the system, it is best to call a professional HVAC technician.
Electrical Troubleshooting
