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.:

picture as example.. not too bad in real.

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.

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?

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%.

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.
