If using non inverter, capacitor failure sure will resulting to more current consumption. As the capacitor is a storage bank for the initial start up of the outdoor unit. Happen to mine last time.
When it trying to kick start the outdoor unit, it will draw the most current and because of the capacitor can't store enough energy, it will keep on energizing until the unit starts. For 2 weeks run because of this, my bill was rm10 higher.
When talking about air cond's efficiency, everything comes in to play, buying rm18 of DIY air cond cleaner will do wonders most of the time.

Faulty capacitor will not start up the compressors. It's only kick start let's say 6.0amp and if the capacitor rosak then it will turn 0 amp. The compressor won't start run. If you notice is not cold you'll fix it within a week.

I know the price are cheaper, but just not worth the hassle.
And some still thinks that when servicing air cond, rm120-150(for 1.5HP), the job scope only includes cleaning the indoor unit, outdoor unit different charges doh.gif
*
120 to clean 1 unit indoor is a reasonable price. + not forgetting travel fees to your door step. Even you ask a computer technician format your pc that will cost how much? All these are services. And these services are necessary to do. Even your car need to change black oil? A lot people don't appreciate with their air con and don't know when to carry out services. Easy speaking. They don't care at all even take down the filter to wash the simplest thing also cannot do.

They charge min of Rm200 to clean the air con inclusive dismantle the whole unit. Maybe compressor will wash and require long ladder to reach it. A well experienced technician will know what to do with your air con. But some they charge sky high and maybe do a little job which not worth the 200 ringgit. Is not easy to find good technician nowadays.

180 pricey to wash the aircon? 200 slaughter? have you all seen a proper cleaning + overhaul before? not much people knows the technique to do it. because people see air con services is easy to earn kinda stuff?

change 1 capacitor 120 expensive? 30uf only sells at RM15 which can get at any electronic shop.

Well, that's why my replace cost only rm120, even I know that fellow slaughter me.
The fact that you are trying to mislead is, capacitor won't die direct, it will store lesser charge over the time.
Funny that a so-called air cond man will try to cheat on this doh.gif
Yup, agree with you on this, and I'm sure good technician category does not include you.
See, the cheater has spoken.
Standard 1HP cleaning is rm120-150 which includes disconnect the indoor unit to do chemical cleaning, replacing the gas and cleaning the outdoor unit(this a bit tricky part as some may not clean it if it is not that dirty, my service man will give discount when he don't clean the outdoor unit)

remove the aircond.
rm150

reinstall 150

so is rm 300

u got 2 unit, u can bargain 1st
*
Remove air con 150??? That's very expensive. Charges for removing is only 50 and standard installation is 200 + 10ft piping for 1hp non inverter.

The tricky part is after take down they usually will ask if wanna clean the air con chemical clean bla bla. Depends on you whether to clean, if dirty of course clean lor. And adding refrigerant. Depending also. If enough then no need add. Usually no need cause they can perform pump down refrigerant to store into the compressor. But if you all scared to be cheated or paying extra Rm60 to refill the gas then simply stand beside him and look at the gauge and ask him if it's enough. Usually they won't lie. I find abit funny cause many freelance air con guy broke the whole reputation of air con industry. People might scared if they got cheated.

Hello everybody,

I just did aircond service which includes:
Chemical wash on both in/outdoor unit
Gas top up
Outdoor unit capacitor replacement

It is a mitsubishi SRK09CH 1hp unit
Been using it for almost 7yrs and it is a good air cond until recently the cylinder fan seemed to blow out a lil like unstable air flow. The blower sounds like it was blowing strong wind but i found the air blown hardly reached over 2m.

The last time i ordered the cleaning servicing was like 3years ago. I think the cleaning gap is ok because i always keep the unit clean regularly and the room is always clean.

The technician was puzzled as to why the air flow wasnt good even after the thorough cleaning process. I watched every step of it. The cooling coil is cold but the prob lies with the weak air blow. The cylinder fan seemed spinning normal. Speed changed accordingly to speed settings but not sure if it  was a borderline case of fan motor failure

So what i did was changing the blower capacitor but nothing change.

And the last thing i did was replace the fan motor but still nothing change.

Still the air blown hardly reach 2m.
Compressor and cooling coil ok.
Indoor fan blower capacitor replaced.
Fan motor replaced.

What else did i miss?

Tq
*
unstable air flow caused by dirty filters or dirty coils. if you say you just done a proper overhaul of the unit then shouldnt have any of these issues.
please check the air flow start from left to right (besure your filter is clean). feel it with you hand goes slowly from left to right ( with high speed) if you feel theres a sudden no air flow from left then have air flow in the middle or right then is most probably your crossflow fan have lost is stable. usually the crossflow fan have clips to make it stable, if the clip lost then you wont have a smooth air flow. same like tyre balancing, they install those clip
at the inner part of the rim. maybe it drop during washing.

and you got conned by replacing the motors and capacitor. sorry to tell you.

Yes, i noticed those clips.
In fact i have 2 clips placed side by side on the very right.
Now how do i recalibrate the balance. Do i just try and error?
*
hohoho!!! this like playing puzzle. different brand air con crossflow fan have different area to place a clip + weighing and amount of clip also different
some need 2 clips some need 3.

and the clip weighing also different. the clip you need to place it everywhere to try it to get back the calibration. not just clip side by side that easy.

and the crossflow fan is rounded. need to try it at every area, up down + left right + clockwise + anti clockwise.

Guys, need help. My aircond living room brand Electrolux never do service maintenance after few years.

Even after I clean the filter, the cold is not it used to be. Do I need to add some gas? Or what?

Can recommend any technian? Subang Jaya area.

Your unit need overhaul. When you realise is not cool and just clean the filters you are late. Basic cleaning of the filters should be carry out 2 week once depends on your usage. If you maintain them well your unit can last longer.

Hi everyone, my wall mount york 2.5hp indoor unit leaking water badly. Outdoor unit still ok. Do I need to change the indoor unit only (where to buy) or is it possible to repair the leaking problem?
*
Ask the technician. What causes the leakage. They only have 2 types of water leakage.

1. Drain pipe clogged. This will leak like water fall.
2. Condensation of the piping. This probably like droplets.
3. Poor concealed drain pipe job (no level) this will easily clogged tour drain pipe if your room is extremely dusty.

If your drain pipe never install properly this will get high chance of leakage + dusty.

Condensation is caused by FCU poor air flow. Suggest to service.

Drain pipe flush down with chemical. Can buy at any DIY shop. Usually they don't carry these stuff. Get for them.


And. Never buy those can spray to spray your coil. It only get worst when the contamination flow into your drain pipe. It will stick when it's dry. I personal don't recommend this. If the can can works like a magic spray. Ac shop no need to do any servicing. Spend a little money to do the service.

please help recommend. i have a 460 sq feet studio apartment that gets morning sun. currently i have an old 2hp LG aircon which has to be replaced.
1. can i buy a 1.5hp ac for that space?
2. ac service guy recommended i buy Daikin Eco King. is that a good reliable model? if no, what is the best?
3. if buy from lazada, does the price include installation, or is just for the unit?
*
If your current unit is using 2.0hp why you have to downgrade to 1.5hp? It's better get a bigger hp to support your room. If is too cold you can set higher temperature. But if is too hot you can't lower down your temperature.

So this is the design fault? Which mean even if I change a new indoor unit it may happen again....?
*
It's not really the design problem. Air con doesn't design for leakage. There's no car design just to drive on the road.

There's must be something that caused leakage. I'm sure is not the unit. Either the drain pipe or the piping design.

I heard cassette aircond has high tendency of water dripping on the ceiling. Is it true?
*
Not true. Water dripping mostly caused by poor insulating of copper pipe or else the drain pipe is contaminated causing water pump can't fully pump out the water and flow back in to the air con.

Hi,

I had non inverter air-con installed in new condominium by developer, wish to trade-in for new inverter type.

Existing aircon (No use before):
Panasonic 2.0 HP (CS/CU-PC18MKH) --- 1 unit
Panasonic 1.5 HP (CS/CU-PC12MKH) --- 1 unit
Panasonic 1.0 HP (CS/CU-PC9MKH) --- 2 units

Plan to replace with following Panasonic Premium model:
2.0HP CS-S18SKH (CU-S18SKH) -- 1 unit
1.5HP CS-S13SKH (CU-S13SKH) -- 1 unit
1.0HP CS-S10SKH (CU-S10SKH) -- 2 units

Need to replace the copper pipe.
Reuse back the existing electric point and water point.

Pls recommend aircon installer.
*
Model too old + no warranty. Better keep it for own use in future. Trade in also 100 - 200 + is r22 basic pana model.
