Hi guys

So I usually dismantle my wall mounted Aircon and wash the blower, filter and top housing with Dettol myself.

Currently my Aircon is not cold.

What service do I need from the Aircon technician? Just add Aircon gas?

Possibly got leak, how old is the aircon

Outside unit needs to be cleaned as well

Need gas topup perhaps.

how old is the AC? When is the last time you have technician to service your AC?

You dismantle the whole indoor unit for cleaning or you only dismantle the plastic casing & cleaning the cool & blower by pouring water on it?
If it's latter, better ask a proper aicond technician to do a through cleaning, most likely the cooling coils are clogged

tons of reasons.

unless you have the diy skills or the knowledge of how aircon and electricity works.......no point for me to list them out.

Outside condenser also need to clean, no clean can't dissipate heat good enough overall pressure high will cause not that cold inside and high current power usage.

Aircon is maybe 10 years old? Never serviced. Just routine DIY cleaning of the indoor blower, housing and filter with Dettol (I'm a bit ocd and have sinus issues) maybe 3 times a year. That's the only basic "servicing" I know how to DIY.

With the MCO now I've got reduced income therefore don't want to spend much on unnecessary service. Any idea on what services I need from the aircon technician? There seems to be many:

1. Chemical service (indoor?) I don't think I need this.
2. Normal service?
3. Gas top up

This is the catalogue from the technician:

Better do chemical clean

Top up gas if there is a leak. Now a day technician found not enough gas, they just top up only. Never check where is the leak. If they fix the leak, they lost future business. Finding leak is also very tedious.
If 10 years didn't dismantled the pipe joint then your problem most likely is not leak, if it's leak then possibly the outdoor coil or indoor coil corrosion which is wasting money to repair.
If not leaking then there are many possibilities. Indoor thermistor, outdoor thermistor, outdoor fan motor, capacitor or even the compressor.
If AC is 10 years old, my advice is to replace a new inverter AC (if yours is non-inverter).
Did your AC got any light that blinking? You can search the manual to see the fault code from blinking light.

once in a while, kena call aircon services specialist to do it!! they know best.

This is very helpful thank you. It's a Panasonic inverter. Yup got light blinking and its red colour light. Then turn off and turn on again the red light will go away. But after awhile it will turn on again and start flashing. This usually happens during the day when its really hot outside. At night very rarely the red light will blink.

I think the manual throw away already lol.

I just chemical cleaning for my 10 years old ac also. The technician dismantle wall unit to wash filter, coil and fan separately. Also washed the outdoor unit and top up gas. From the need to set 18c , now only need to set 24-25c and it's cooling faster.

Only cost me rm160, regretted didn't do this earlier lol

Same like me, just did a full aircond service for only Rm160, coolhero. They clean up the indoor unit, outdoor unit using chemical, and top up gas. Now faster cooling

Can share your contact bro? Chemical cleaning + outdoor unit + gas top up only 160?

Wah chemical cleaning + gas top up only 160? That's alright. Cheaper than mine I guess.

Google the manual with the model.

Yes, rm160 all in

Go facebook search for JC air cond Eng

The best part is, they dismantle the wall unit to do the chemical cleaning not do it on the wall.

highly likely it is the indoor unit coil sensor issue.

Wow not bad thank you!

Since this topic is up, Im so new with aircond last year only started to own one. My aircond is LG inverter 1.5hp. I know Daikin/panasonic is the best but that time I have zero knowledge about aircond just bought from surveying and available stock in the shop possibly next room will be different brand.

1) I would like to ask how often should service the aircond? once a year enough?
2) What is the cost should I be expecting for servicing ?

basic service need to do every 3 months if you use the AC... daily .

try DIY if you have time .
clean filter
spray WD AC cleaner on the fins .
turn ON to wash down the AC cleaner

done..

many tips on youtube.

1. services depends... mostly no cold ald only seeking for services. ordinary service self do lo. depends how dusty on your area also.
2. they charged based on horse power. cuci+topup probably rm1xx+ . some dismantle indoor n outdoor unit, some not using dismantle method to clean. dismantle one will be clearner.

This is the one ? Are they reliable ?

So far, based on personal experience, yes they are reliable

whats the running rate of aircond service?

Still using their service till today ?

seems pretty good reviews around

will check them out

thanks

0139808278 (Whatsapp Ms Teh) for appointment

Yeah, in fact I like their service so much I engaged them to purchase and install aircond for my new house 😂

To be honest, I have my own favorite aircon service company (Wan Bin Air Conditioning Systems). I've been with them for almost 5 years. They have been super reliable, honest and trustworthy until they went missing this year
Now, my company needs air conditioning service likewise my house also requires air conditioning maintenance. Therefore, I am currently looking for a reliable company and I think found 1

Just to check, for each engagement, will they send the same people or will it vary depending on whoever is available on the day of the appointment?

For my case which is consumer type service, it will be depending on their roster/availability as it's long apart between services 😂

For business, then it may make sense to have same people do but I have no experience with this ya

Thanks bro for recommending them to me. They are really great. Prices are on the higher side but they are definitely worth it. I'm happy with their service.

Good to hear that. I've also just recently asked them to service my airconds as well. Satisfy as always, very punctual too which is important to me 👍

when cleaning blower, did you remove the cylinder blower to wash? most time cylinder blower accumulated dirt and not effective.
If the air is not cold, mostly need gas.

refer to part 7 remove cylinder blower

I know it seems counterintuitive, (eg "it's safer to fly commercial than to drive") but my professional opinion is to never break the flared seals of the copper pipes, if all you need is a cleaning and servicing of the air cond system.

True, taking the IDU off the wall and taking the unit apart for cleaning could result in a cleaner unit overall, but you should not do it when balanced against the future possibility of leakage, air or moisture in the system, or loss of gas, ie the unit will be cleaner, but it will work lousier.

Hey.. a bit off topic, but I can’t help but notice you have Doraemon as your avatar too! Hahaha

You’re right. Breaking the flared seals of copper pipes isn’t worth the risk. While deep cleaning the IDU might seem beneficial, it can lead to leaks, moisture buildup, or refrigerant loss, making the system work worse over time. Instead, professional air conditioning repair focuses on cleaning filters, evaporator coils, and drainage lines without disturbing the sealed system. If your aircon is not cold, the issue could be clogged filters, low refrigerant, or a faulty compressor.
For a safe and effective fix, getting expert servicing is best. Check out air conditioning repair for reliable maintenance!

Gas top up, if still not cold then check if there a leakage
