How to clean your Air Conditioning Filters

To ensure that your Air Conditioning System runs at its best efficiency and you receive quality air it is important to maintain and clean your filters regularly. Airflow can be reduced up to 50% due to clogged or dirty filters that block airflow and reduce efficiency significantly.

For your ducted Air Conditioning system Ford & Doonan recommends cleaning the filters every three months, which can be done by yourself, however, if you are unsure our service team is happy to assist. If you have allergies or pets we suggest cleaning the filters every month, especially during summer. The ducted Air Conditioning system will have it filters where the return grill is usually located in the ceiling.  Split systems have the filter mounted in the grill that faces into the room.

Nearly all filters are reusable and washable. There are some filters that need replacing.

There are just a few simple steps to clean your filters.

For your split system: simply pull the filter carefully out, whilst being aware that the vent behind it is not damaged. Then rinse the filter in a sink or tub using a little dishwashing liquid and a soft brush to get any additional dirt out. It is best to let the filters dry naturally. Once the filter is dry we recommend going over it with a dust buster or the hose of a vacuum cleaner to get any left dirt. Once the filter is clean and dry you can just snap it back into the unit.

If you have a ducted system: unscrew the retaining nut. The frame will hinge downward exposing the filter. Slide the filter free from the frame. The best method is to hose the filter from the clean site until all the dust is off. Then you can hose from the other direction. Shake off any excess water and leave to dry naturally. Once it is completely dry, re-install the filter to the grill frame, close the frame and screw grill back together.

If you are unsure at any stage of cleaning your filter, please contact our service department.
