For the air-con unit inside the 3 rooms, i service myself. Dismantle the cover, filter and the main cover. Wash them up and next use a soft tooth brush and a small pail of water. Slowly brush down the fins and you can see the dirt being remove.

Take note, if 1st time do this very siong and take almost 3/4 day time. Neck and hand also very tiring but worth it. The 2nd time you do it will be a breeze. You will notice your room is colder than last time b4 cleaning.
