I have 2 layers of filter .. another layer over the original. Dirt slower built up in the blower and coil but wind affected slightly.

yes i have this too ,
for my daikin 5 yrs old , it seriously effect the wind pressure . maybe getting OLD

Most AC s the original filter is seriously lacking ... big holes i would say .
they do this cos want to claim a strong wind velocity out of blower . at the expense of more dust getting on your coils .

DIY service air conditioning with a tray and hand spray pump


this diy is fine but he miss out cleaning the Fan .

if you already open the cover might as well also clean the fan .
A clean fan will give a stronger Wind . plus less noise .

Anybody using this?

Seems like it was introduced 5 years back


The product in action



And possibly also here as seen in the first 30 seconds


Compared it to this tool which could be gentler albeit high pressure


This one provides quite an insight as to what is useful and what is not in terms of spray tool (58 seconds onwards). Right tool for the right job.


This is already mentioned in the AC thread but its worth mentioning again. If the AC is equipped with it, use clean mode regularly. Those models not equipped with one button clean mode function and if the AC has fan mode can simulate it. For such models, set the remote control clock to current time and after AC usage, set to fan mode and timed it to turn off 2 to 2.5hours later. Or combine clean mode and fan mode if permissible (Samsung Triangle inverter AC can do this). Doing this slows down mould proliferation so that the interval between cleaning can be lengthened. Some models like Sharp inverter with plasmacluster eliminates mould quite well (it redirects that air flow into the cooling fins and by that effect also its drain) that only the pre-filter needs to be cleaned.

Would like to ask for those who frequent diy cleaning coil with those chemical cleaner, will these chemical damage polystyrene drainage tray? All of my panasonic ac has polystyrene material as the tray leading to drainage pipe.
Just ordered those kleenso ac coil cleaner which states it biodegradable and safe on plastics but no mention bout polystyrene.
Safer method would be removing the drainage tray but additional stuffs to remove, so if the chemical does no harm i dun wan to bother remove the drainage tray as additional wires to swing motors and IR sensors need to be removed and i not confident can install back later. So would like to seek feedback from all sifu here

i think should be safe to use kleenso.
Do a test first just to be sure . spray some on the polys material and see .

what pana AC model is this .
I have a few pana AC but never see polystyrene drain tray .

The older ones like CS-KC24QKH & CS-PC18QKH. I drop kleenso a query and got below response:
The Aircon coil cleaner is pH 1-3(acidic)
The purpose is to clean the coil
When cleaning process, shut down the aircon
After the bubble blow out the dirt and clean away the dirt
Then spray with water, then only on the aircon
Then the water only go out from the drainage
Then after dilution
It will not affect or melt the polystyrene drainage hose
The acidic ingredient is just few percent and more than 90% is water dilution, the dosage u use is very small .
So, it is safe on the drainage
But,do remember to follow the instructions.

All AC have that, else how to drain the water.

A high pressure water hose from main should clean all dirt. No cleaning solution needed as there is no gas leak.

check lah ... this drain is white poly ...same like in packing material in box of electronic goods.

today they use some solid plastic .

----------------------------

After watching the hydroclean video .
my conclusion is
1. you need a strong chemical to deep clean the coils . front to back .
2. you need a strong water jet to wash out the dirt .
i figure this should be a yearly service to do.

i only saw video of the bosch jet washer ..cleaning coils .
the jet pressure can be controlled from to 20 too 100 bars..

All my pana ac have those. Outer layer plastic, inner layer poly.

Havent bought new ac for the last 7 years.

cut the hassle, hydroclean could do the work well.

i dont see this hydroclean available in malaysia ?

what I mentions was for DIY enthusiasts to understand what was needed to do a good job

It is available.

https://www.carousell.com.my/p/hydrokleen-a...vice-149066805/

My input not yet as the customer be.

1. the structure of Malaysia hydrokleen company is bad weak, it is a good service product BUT handle by non-visionary business people. <Jesselton Sdn Bhd> <Hydrokleen Service Sdn Bhd> It is like having hawker store everywhere but very weak revenue generating OR low profitability gain business.

2. It can be franchise up well here running from north to south.

3. Looking the counterparts in SG (its under passionair) while Brunei, (A-konkleen), Brunei have their business so well going, booking filled up every month. It is a very good start for a company less than 10 people servicing the entire Brunei country!

4. Problem with Malaysia, too many expert wannabe, lack of REAL expert with industrial input/commercial <.> end consumer feedback; thus the market branding and penetration is very weak.

5. it need to be restructure in Malaysia one.

DIY cleaning is fun, but think of the input cost to get it right.

I think thats a bad example to go by la. My hubby always DIY our AC. The dirt condition is not even close to that video. If we maintain it often, one dont need those expensive tools, just normal water pressure is enough to clean it.

yes... if you have 5 AC s or more to maintain
and want the AC s cooling performance to be tip top ...better to DIY if got the time .
and maybe every 3 years do hydroclean .

yes true .. will mean every 3 to 6 months you need to diy.

provide you know what you are doing which generally most don`t. And damage the coil/air cond part..
that`s worst.

And once damage, long run performance drop etc. Blame the manufacturer.

LOL...betul gak....but after watching and helping my other part, I should be able to carry out myself
