KaKiLang 4th Gear August 14, 2013 Share August 14, 2013 Never use chemical to clean air con, bad for children when breath in. Use hot steam jet better. Link to post Share on other sites More sharing options...
Orangechem Neutral Newbie August 14, 2013 Share August 14, 2013 Easy, I did mine myself, damn A/C service company wanted to charge me $100 PLUS FOR ONE UNIT. I have a split 3 and the compressor will be extra charge. You can actually purchase the coil cleaner from chemical company but they sell in bulk so get the spray type either from those hardware shops, JACKY brand will cost about $12-13 a bottle, should be enough for 2 units if you want to the VERY CLEAN. First remove excessive dirt by vacuum , use also a used too brush to sweep away those stuck between the grooves. Now just spray the chemical onto the coil , 2 applications should be sufficient. same goes for the compressor. (Remember Gas last a life cycle of the aircon, no need to top up) That's all/public/style_emoticons/default/rolleyes.gif Link to post Share on other sites More sharing options...
KaKiLang 4th Gear August 14, 2013 Share August 14, 2013 You oso need a wet vacuum to suck out all the gunk stuck in the drainage ducts. Link to post Share on other sites More sharing options...
Wesleyoh 1st Gear August 15, 2013 Share August 15, 2013 Never use chemical to clean air con, bad for children when breath in. Use hot steam jet better. hot steam cant really remove the dirt in it. Chemical is surely much better and the chemical will not stay in your air con system for long. I install and service air con for 15 years and always advised my customers to take down the whole unit for chemical overhaul. cleaner this way. But i do agree DIY with chemical is also a good alternative and you can DIY yearly to maintain clean air conditioning. Just make sure to wrap the electrical wiring well to prevent it from getting wet. Link to post Share on other sites More sharing options...
Sabretan 4th Gear August 15, 2013 Share August 15, 2013 You oso need a wet vacuum to suck out all the gunk stuck in the drainage ducts. Yup a true n valid concern. So wat I usually do is, after letting the chemical works thru the coils, and washing the filters, I turn on the air con full blast for 15 - 20 mins w no one in the room. then juz open up all the windows and turn on the fan to clear out the air.

Opel17 6th Gear August 15, 2013 Share August 15, 2013 Do you have a step by step to dismantle the unit? I think it would be helpful for all who want to DIY themselves Dismantle the unit is not recommended for ordinary DIY folks like us. Because the aircon pipings [discharge Freon into service tank] and wiring need to be disconnected for removal of the unit. And during re-installing, the aircon piping and wiring need to be re-connected. And aircon system need to be be evacuated [vacuum to remove air & moisture], refilled with Freon gas. The person doing this have to be on the aircon ledge. Imagine the aircon ledge on the 15th floor Based on these scope of work, it is no more DIY. Therefore, recommend to DIY only with those aircon cleaner [eg. Jackie, etc.....]. Link to post Share on other sites More sharing options...

Lalapunch Neutral Newbie August 15, 2013 Share August 15, 2013 I last time work under one of the air con servicing company before, actually the "chemical" they use is just those normal detergent like mama lemon. Plus nowadays you can buy those coupon from website like groupon, deal.com for serving of air con. The price quite cheap actually, around $20 can get one already.

Mkl22 Twincharged August 15, 2013 Share August 15, 2013 the chemicals need to be washed off right? yes MUST be washed off. best method is still to dismantle the condensor and chemical wash. You can chemical wash it attached to the wall, but make sure you flush enough water to get rid of the chemical else the coils will get corroded over time. Dismantle the unit allows you to flush the back of the coils with water to get rid of the dirt. with the unit on the wall. sometimes you get the dirt still clogged on the insides.

Die... I used the Jackie spray (S$11.90 at Giant) to clean my room air con. The instructions on the bottle did not say to wash off leh... But it works damn good cos my contractor of many years lazy to fix the issue (blocked fans resulting only in blocked vents as well). The spray worked wonders, so good my wife no longer complain it's warm in the room but si bei damn cold... Link to post Share on other sites More sharing options...
Darky8888 4th Gear August 15, 2013 Author Share August 15, 2013 i did purchase Jackie spray at Giant too but always have the feeling that it is not clean enough. those with forms are more convincing as we can see the actual dirt being wash out... where can i get those chemical? and can it be apply on car aircon?

Mkl22 Twincharged August 15, 2013 Share August 15, 2013 you can buy the chemical from horme hardware or any aircon repair shop. but these are the strong sodium hydroxide and WILL CORRODE the coils if never flushed properly. those in spray cans are probably the mild form. but you still need to switch on the aircon and let it run for a while to allow the condensate to flush out the chemicals.

Hmm... Jackie spray got foam also ah. Must shake damn hard and spray. The foam will expand half a sec - one sec after spraying. ↡ Advertisement Link to post Share on other sites More sharing options...
