I tried the DIY aircond cleaning.. quite good since I have total 9 airconds at home.. I cleaned 7 airconds in two days.. only the indoor units.. total cost was
- RM20 for the spray pump bought at Ace Hardware.
- RM46 for the coil cleaner bought at Ace Hardware. I think this is not a good one though. Not the foaming type. Still have to use brush to clean the coil.
- RM7 for the big plastic to channel water from aircond out to pail. I bought the ones people normally used for covering floor when painting. Bought at hardware shop.

yeah.. cannot tahan la one aircond they charge RM150.. once I clean, the aircond really feel different.. much colder and blower also more powerful..

My compressor not so difficult to access, it's just that I could not find a foaming coil cleaner like the ones used by the professionals.. if got that, it would be easy to do.. anybody know where I can buy those?

I could not find the foaming type. I assume it would be better because if it foams, then all the dirt can be dislodged easily.. otherwise you need to use toothbrush or something like I did.. not that dificult also la..
