hi, this youtube video is by MH370 captain........

lol, to be fair his videos are quite in depth especially refilling and purging the aircond refrigerant.

R u serious?

of course, it's true

ohman was being serious

i have watched it before

apparently the pilot did some diy like this in his spare time, also his most viewed uploaded video too

for sure some mh370 comments are in there too

i see today they can do chemical clean with pressure spray on the Indoor unit . right ?

I am wondering if you use chemical clean DIY or with service tech , will this damage the fins
how often is the recommended chemical clean ?

I don't use any chemical if DIY clean. Only general detergent. It is good enough.

If you want to use chemical, can get it from ACE or aircon parts supply shop. Makseure you read the label about safety.

Pressure spray have 2 type. If you using the pressure motor pump, yes, it would damage the fin. Unless you know how to use.

Another type is hand pump. This wan is safe. I use this spray to clean the fin.

what type of general detergent do you use with hand pump.
can this clean off the dust ?

i normally use wd 40 aircond cleaner . but now i see the price up to 20 rm

want to try other like kleenso , what do you think ? at 12.5 rm
i have 6 AC s so lookin to cut cost .
normally i use 1 bottle of 2 AC s . if i do double wash 1 bottle per AC .

Didnt expect you to replied.

Read his previous posting saying diy is time consuming.

Ok never mind about the above.

Generally water pressure from direct piping should be able to do the job, unless there is coil leakage. Is only dust.

time , i have these days

i figure to clean the indoor coil and fan DIY will take about 1 hours after some experience .

How often you do it ?

Any general detergent or multipurpose liquid cleaner. Can buy from supermarket.

At the end, it is the spray water that flushes out the dust.

Normal cleaning only la.

Call service, once every 2yrs. Cause I can't bring the aircon down and deep clean.

3 to 6 months depends on AC usage .
with WD 40 cleaner .
i figure if more regulary the dust on the fins dont get thick .

Seal the window and door properly. It help reduce the dust and cleaning alot.

why need to bring down the Aircond . unless you not clean for like 5 years .

the service with chem spray and pressure jet without bring down unit seems most popular today ya ?

yes .
Klang Valley houses most places i see heavy dust pollution .

It is normally what the serviceman do. Deep cleaning I guess.

Wd 40 water or oil based? Havent use b4.

one of the best , but price keep go up.
very safe .

3-IN-ONE WD 40 Professional Air-Conditioner Cleaner is a water based cleaning agent which dissolves grease, dirt, fungi, mold & other build-up from the cooling coils of your air-conditioners. After cleaning, your air-conditioner will cool faster. thus saving electricity.
