The filters in a ductless head should be cleaned at least once every 1-2 months. Cleaning is simple if done often. For most units, lift the front plate of the ductless head, remove the filter and vacuum off the dust. In some cases the filter needs to be washed in the sink with some mild dish soap. If the aluminum fins under the filters are clogged with dust then call Canadian Aerothermal for a full cleaning of the ductless system.

Every 1-2 years it is recommended to have Canadian Aerothermal to do a professional cleaning of the system. We fully dismantle the indoor ductless units and clean all surfaces. The outdoor unit is inspected for potential issues and cleaned. Canadian Aerothermal will provide a report on the system and a recommended cleaning schedule based on the technicians findings.
