Decided to share it here, DIY have help saved lots of money. Been cleaning 5 of my Daikin units for awhile, it's pretty easy and cost saving unless gas top up is needed, only then I'll call in the repairman.

Below are some videos to guide you along. Ensure you know what you're doing to avoid damaging any parts. Second video shows you how to vacuum inner fan blade, removed obstructing plastic fins so as to reach further inwards.

I will also get this filter because the holes for Daikin mesh is quite big thus a lot of dust/dirt can pass through.

nice

when diy, make ppl know wht to do

the biggest problem for me is the blower
other is easy, just buy the aircond cleaner spray, spray it leave it 30 min then it will cleaning it

Can you access the blower by removing the fins? Most moving parts can be removed, just need to know how to do it.

Nice share.

My unit is behaving weird. The metals parts inside (behind the filters) are condensed and turned ice and it will melt causing water dripping.
I found that the blower hole has less than 50% of air coming out which i believe somehow the fan inside is blowing the cold air to wrong place.

Used torch light to see inside found the fan has alot of dusts stucked to it.
Need to do some cleaning but kinda lazy and hard coz below aircond unit got a big cupboard blocking making hard to put ladder.

I did post a DIY method to clean the blower fan here for Daikin -

https://forum.lowyat.net/index.php?showtopi...post&p=67323305

Nice info bro and thanks for sharing.

Perhaps you can motivate yourself with the saving of RM130-RM150. I managed to vacuum away the dirt that was stuck in the blower. Air flow was smooth and strong after cleaning.

thats what I like about the Daikin, can take out the fins to get to the blower
usually this is the dirtiest part.

Other brands, not sure.... if can DIY, can save Rm60 per aircon.

Servicing cost around RM130 - RM150 per aircon, at least that's the rate from my repairman. One helluva savings.

what do they do? My service person charges me Rm60 but that is to clean the indoor blower only, not the outside compressor. Actually Rm60 also expensive, I found another that charges only Rm25 for indoor blower and Rm140 for both indoor and outdoor.

Mine includes chemical wash for compressor.

I ask my fren about this matter too
causing ice is because the blower stuck and the air not enough strong, while the compressor keep make the fins cold and cold it will cause ice

clean the blower its the point

i think my model need open up whole cover......
i will try tomolo

I also removed cover so I can wash cooling coil and condenser plate together, do a thorough cleaning and it will last you for months.

Finally found the filter cloth from Diaso, was there several weeks ago but ran out of stock.



Cut cloth according to size of filter mesh then slot it back in place.


Air flow not restricted and negligible. This will help filter more dust and dirt.

I've been doing this since day 1. The blower still gets dirty after some time, but probably much lesser without the extra filter. In fact, I've been using the A/C every night for almost 4 years now, without engaging a professional service personnel. Just remember to change the filter from time to time because if it gets clogged you get reduced airflow.

Yes, we can't totally stop dust from getting through, only to cut down and prolong the period before the next servicing. You must have saved a lot of money by doing own maintenance.

Well, at most we can reach the blowers. The condenser fins still need to be cleaned by the service personnel Even the dust accumulated on the blower fins can be difficult to remove. Vacuum alone is not enough. I had to use a small brush to dislodge the dirt. Quite time consuming.

Cool same like mine.. When from new installed until today, From my blower still using an extra filter, even the Aircon man nothing to said, they said like this case, if everyone to be the same, from their serving program would be cut down 80% ha ha.

The 1st is aluminum fins didn't blocking on dust of the airflow still remain like new performance, just remember for change the filter on every month only.

The link here: http://www.kimrovacstore.com/mitsubishi-el...lean-video.html

Dunno why your can't open

which daiso you went to? i also want to get some

I've been doing this for a long time. Learn from aircond cleaner / technician that used to come and clean & service my office's aircond.

Very easy job. I take about an hour or less. My home aircond have been working well ever since (more than 7 years) without any professional service done..

I'm washing the fins on condenser with a mixture of chemical solution after removing entire plastic casing and cleaning condenser plate at the same time, blow drainage pipe to clear any clogging debris. As for blower, can vacuum abt 90% of the dirt, it depends what model of aircon you are using, mine allowed easy access after removing most if the moving parts. A hard bristle brush is needed to clear dirt that's stuck on fan blade, it can get really messy.

Daiso as Midvalley.

Lol....same here. Learnt from them while they doing all the washing. The only thing we cannot remove is the pipe for gas.

Why I resort to doing this myself is because the repairman failed to clear the water outlet even with constant reminder, water leak barely 3 months after servicing. After doing my own maintenance, everything went well. For clearing dirt build up in pipe, I usually pour a big bowl of bleach and water mixture onto condenser plate, let it flow through the water outlet.

As for cooling fins, I sprayed them with Mr. Muscle (Mold and Mildew), let the foam stay on for 10 mins before I rinse it off with water. Thanks for sharing the new link.

Not that difficult to clean the ac. As for gas piping, as long as there's no leaking (the installation must be flawless) then everything should be good for years to come.


Similar reason why I do it myself. Satisfied with my own workmanship. Nice tips of using bleach and Mr. Muscle...

Do you have a huge plastic bag underneath when you rinse it off with water? Otherwise you have to dismantle the entire unit and bring it somewhere to clean.

Nope, all these water will flow out through condenser plate, just have to pour it slowly to prevent over flow. Dismantling entire unit consist of disconnecting gas pipe, this can only be done by aircon repairman.

WARNING: CROOK AND BULLY- VINCO Sales & Services Electrical and Aircon Services

I was home alone when 2 technicians arrived. They cleaned my ac with just a cloth and took out the opening cover and filter to the toilet for washing (which is less than 10 mins job) and refilled my ac gas without my approval. Best thing is i asked for 1 to be clean and they cleaned 3 and told me after. I didnt want tell them off cuz again, its done and no point arguing over it especially when there r 2 of them

When they invoiced me the amount, i nearly fell off the chair. I felt cornered and didnt wanna make a scene as i was home alone with these 2 men. it is ridiculously high and its not right to bully a home alone woman like this. I called the boss up later and complained about this, he gave me a discount of RM100 but i'm very unhappy with this and i told him to keep the balance as I'm bringing this forward to share with all my friends especially housewives or single women who might feel bullied by these kind of behaviour. If you want your aircon clean at max half the price, PM me.

OR BETTER STILL DIY.

I haven been using solvent based cleaner from USA. Problem is when used it there is tendency to inhale the mist. I ended getting asthmatic attacks. Then I switched to safe biodegradable product recently through online. The company gets it manufactured in Singapore. Check it out Www.pranafas.com. I bought it via lelong.my. I asked whether they have cleaning bag for washing the blower. Currently under R&D. Nevertheless they even shared how to do your own bag from any large bag especially garbage bag. It's easy. Cost me less then rm20 for the bag+Sprayer pump. For blower cleaning you can dilute with water.

Replaced Daiso Aircon filter cloth few weeks ago, see the amount of dust and dirt trapped by the cloth. Overall I'm happy with the performance, cheap and useful. Without this filter, those dirt will get into the fan blade. Air flow not restricted in my opinion.

Used filter cloth after 2 months - Left / New filter cloth for replacement - Right

How long was this?

Feel sorry for her. Hope have found a reliable repairman.

2 months, should have change it after a month but was too busy. Shocked when I compared it with a new filter.

Your place must be very dusty. Mine doesn't look that bad even after 3 months, and I stay beside a busy road. I never open my windows though.

My windows all closed, this unit is in the living room running more than 12 hrs 24/7.

Xcess, these filter sure runs out fast at Daiso. You must be buying them by the carton?

Lol....I'm not the only one buying. When I first went there, it was out of stock too. Bought it on my second trip, only purchased 6-7 packs. You may want to try other branches.

LOL, ok thanks.

Did you know that Aircon filter can be wash and recycle used?

I did it long time ago.

Good so far I had see you guys already in used with DIY Daiso filter, at least you guys know my answer before.

How dusty they are for sticky in fins else.. Really not easy to clean out and almost blocks into fins and the difficult to intake new air also blower works harder

this DIY daiso filter can be wash and reuse ???

Better change new ones. Not that expensive especially when buying from Daiso.

I did it for wash and reused ha ha

i just bought this yesterday and try out.

waxco diy aircon cleaner.

quite effective to clean the dust inside cooling coil.

after spray left for 5mins to dissolve with dust, then turn on aircon for 15mins minimum as per instruction, but i turn on straight 2hours.

the condensation in the cooling coil will cause water droplet bring along the dust and drain out automatically from drain pan.

so it's a real easy diy to use.

after complete, only remember forgotten to clean aircon blower

Daiso should slightly different from aiexpress or TB

If there is aircon mold stick on the metal fin, how to remove it?
It become harden even vacuum and brush cannot remove.

I'm using a stiff brush, if it doesn't clean well, perhaps it's time to call in Aircon servicing.

That kind of rough.. very easy bend the metal.
no choice liao, really need their expertise.

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.

Wa 9 aircond son, save lots of money

To clean the blower, use Aircond cleaning spray is easier and more efficient.

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

Yes no choice air cond need maintenance. Also the compressor require cleaning if not will be efficient just cleaning the blower

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?

Let me know anyone would like to know how to clean. I can give free lesson.

i just take out the aircon blower, spray with magiclean kitchen cleaner, wait a minute then hose off - super clean. taking the blower fan out and putting back in is a 5 minute job. while its out can also clean the innside unit nicely with damp cloth, brush over the condenser foil if needed, wipe the casing and there you go - good as new. outside cleaning also similar, just spray the fins with a sprayer. i use mainly warm water and add a bit of magiclean kitchen cleaner to and some detergent. creates a nice foam. let it stay (normally i spray the compressors one by one and only once the last one is done i star at the first to hose off. cleans pretty decently also, so i can get 6 outside compressors done in approx. 40 minutes.

1. Remove the directional plastic flaps
2. Fix the brush onto your vacum cleaner and start brushing the blower wheel inside. No messy liquid on the wall/floor


You can vacuum the filters with this too without even need to remove them and wash from its slots

Someone told me newest air cond., the blower wheel is removable without unscrew anything but im yet to find any model with that feature.


The blower wheel

Hi guys, i'm new to aircon cleaning. Decide to diy.
I live in condo.

Clean the these parts enough? How about the compressor? It hangs outside, so danger to clean.
1) aircon filter mesh
2) the long cylinder shape blower
3) the coil fin

Really, can teach me free?

can you teach me?

Bro, i like this one. i believe all of you shared the experience and information will be great and benefit to all of us.
@wz3k , you mean buy foam type will be good to use and clean?

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..

Which part of the aircon are you trying to clean? the external compressor or internal unit? For internal unit, are you able to remove the exterior plastic cover? If not, perhaps try source for video instruction on youtube or watch how your aircon repairman do it next time.

By remove exterior cover, it's easier to wash and clean the cooling fins, spraying foam and brushing it with a fine toothbrush will be more effective.

I got a worker once to spray thecleaning coil fluid at the external compressor (only) followed by good rinsing. Colder after that.

Recommended.

I try tmr using hot water to spray, see effective or not. Tq bro

notice some mold build-up near the blower.. AC unit quite new.. less than 4 months of using..

anything we can DIY to clean? like sprayer? e.g.:

Get a AC guy to clean. Are you in Klang Valley? That's why now I go for air purifying AC with ionizer that cleans the internals (clean mode, mould proof operation, auto clean depending on manufacturer and model) as they will kill the mould inside.

This post has been edited by halcyon27: Mar 28 2017, 08:03 AM

but even after pay to clean, the mold could be still build-up sooner or later.. lately room only just put Sharp Air Purifier

Yes, this age-old problem would never go away since the advent of AC until self clean feature came to the scene.

The air purifier for the whole room only works to clean the air around it. While it lessens the hazard, it will not be able to target specifically the cooling fins, blower and drain. That's where self clean mode comes in because it deals to a large extent on all three areas.

Having said that, AC maintenance for blowers usually targets not just dust accumulation but condensation induced mould growth. Sometimes if left unchecked, the dust and mould combo can clog the condensate drain pipe and that AC overflow. Only regular blower maintenance prevents this but it will be ongoing for the life of using the AC. Only self clean modes lessen that to a longer interval or in some cases none at all. That still doesn't prevent dust accumulation on that pre filters.

Why there is mold on the blower side?

Aircon air is dry. Wrong setting?

Check your humid during using aircon.

AC air is drier but AC pipes at the fins will sweat due to higher indoor humidity whilst in operation. Mould growth cannot be avoided. I've seen or heard of it in all AC that's not been serviced.

I would have thought this is general phenomenon unless an old technique is being overlooked to deal with this apart from blower unit cleaning?

This post has been edited by halcyon27: Mar 28 2017, 10:45 AM

I don't have such problem. There is only dirt at that blower side.

Room humid during aircon is 40-45%.

New type aircon normally have antimold treated on the fin, water tray or some parts.

The air blowing out is dry. So shouldn't be mold grow on it. Unless at the water tray below the fin.

Shouldn't water tray should be below the fin? It drains away the condensation water. It makes sense for the tray to be like a drain. Condensate water drips down to this. Humid air will always sweat at the heat exchange pipe covered under the fins.

Wow 40-45% that's quite dry. Better drink lots of water. I just ensure mine stays around 60-65% on average and no lower than 55%.

This post has been edited by halcyon27: Mar 28 2017, 11:42 AM

what about using DRY mode? does it helps?
also, how to check humidity level/%?

Dry mode basically dries the air. The AC will still sweat at the heat exchanger except that the air produced is mildly drier than before but temperature may not drop as much. Basic dehumidifier function.

Get a hygrometer from Ace hardware or Homefix sells Stadler Form Selina. This will read your room's humidity. Some wall clocks like Seiko or Citizen have thermometer and hygrometer built in feature.

ok, will try get one and try.. what is the recommended humidity level/%? for room/living hall/kitchen?

I mean the mold will grow at the tray since the water will remain in there. But not at others area.

Level of humid depend on the temperature setting. The lower the more dry. 40-45% at the 24c temp setting.

I don't have problem with this level humid. It doesn't consent me if 40% or 60%. But not over than like 70%+. Can feel the stuffy.

You can buy at ACE or Caring, watson etc.

I have the sharp air purifier which have humid reading. So I can see my room humid.

Ok got what you mean. By right it should drain quickly and not stagnate. Mould can proliferate where dust adhere to cold area where heat exchange happens.

By right, all the aircon now have the antimold chemical to protect from mold.

Shoudn't have such issue anymore. It is not a new feature now.

If you search some aircon website spcification, it have list down like antimold.

http://www.sharp.com.my/pageRender?msgCont...AHXP10SHV1#tab2

Works for a limited time as chemical resistance can build over time. The plasmacluster method of cell wall breakdown is much more reliable. Anything anti-x won't say doesn't work but only offers to build up their resistance. Like hospital bacteria strain that are this resistant or that.

this one can use?

http://www.lazada.com.my/easybuy-built-in-...41844.html?ff=1

"Stadler Form Selina" is too way expensive..

Indoor Humidity at 80%RH at 24°C (Cameron) is nice but at 80%RH at 28°C (e.g. bathroom) it's very stuffy already..worse even at 29°C onwards. Tiles will repel hence, the place will stay damp or humid vs marble which will absorb it.

Old AC without inverter has a very straightforward program that dehumidifiy and lowers temperature but beware of long term health effects as the lungs can dry out. Old folks and young children health will be a concern.

Newer AC inverters have a human comfort level that keeps it at a comfortable humidity-temperature range. 45-65% is comfortable but 60-65% is not too drying healthwise which I sense is optimum. But different ppl have different preference. Some like it colder which is because it's too warm in the day or even the night due to room configuration (evening sun) or just used to this feeling.

What tricks the mind to perceive comfort is moving air. Ceiling fan is the great helper here. If you can get the AC to blow towards the ceiling fan e.g. Coanda effect, the added windchill should allow setting the AC higher like 25-28°C depending. Or even dry mode.

Kitchen should be colder as esp where cooking is done.

Should be good enough.

still confuse

cut it short, what is the ideal humidity level to watch during sleep?

air cond use (basic one):
http://www.panasonic.com/my/consumer/home-...2skh-1_5hp.html

sleep with 24C, fan blow auto, mode use iAuto..

also turn on ceiling fan with minimal speed at 1..

by the way, digital better or analog?

If you want to hang or put on the table, get a nicely look la.

table type
http://www.lazada.com.my/sh-high-precision...05109.html?ff=1

hang type
http://www.lazada.com.my/lcd-digital-therm...68773.html?ff=1

yah.. will do.. considering those wall type..

Mentioned before...up to personal preference. Mine is between 60-65%RH at 27°C.

if 24C?
