what's are the probably causes where at night aircond set at 25 used to be just enough cold and comfortable for sleeping, but recently 25C become warm and i have to lowered to 24C to get the same environment as previously?
I have washed the mesh filter, air cond age 1 year+, only on at night 11pm++ till 6am ++ a day
There are couple of ways to clean it, if you dont want to dismantle the blower unit.
- as described by Decapix, you can use tooth brush.
- you could also buy cooling cleaner, available at most of DIY shop. It acts like a degreaser. Just spray, and let it sit for a while, and turn on the aircon with fan speed in high.
better still, if you could use vaccum cleaner to blow after the spray, it helps to push the sticky dust thru the fins.
you could also use, some water to spray after using the cleaner or could pour slowly some water using a pail scoop. Depending in your blower location and convenience.
- also do clean the blower roller as well, using toothbrush.
Perform the above every 3 months for heavy usage.
