    Dismantling a split aircon unit is NOT for the DIY'er UNLESS one has got practical experience and knowledge of refrigeration equipment.
    Just to explain, one needs:
    1. Refrigerant manifold gauge, to charge and discharge the refrigerant.
    2. Air evacuation suction pump
    3. Refrigerant.
    4. Neccessary tools including allen keys.
    5. Knowledge of the proceedure including electrical safety.

    Chemical cleaning is to dissolve and loosen the contaminants, which the next step of pressure washing would remove nearly all of it. Refrigerant pipes have to be sealed off immediately. Both the blower and fan coil would have to be washed thoroughly and that'll involve stripping down the fan coil assembly especially removing the electrical parts and motor to allow pressure wash. This can be done effectively when its OFF the wall and in the open air. This is the most effective overhaul and it'll be like new.

    Without all those, please folks!..don't ever dream of dismantling one!.

    I have been using my air con for more than 5 yrs and never get anyone to service them. But periodically I make sure the filters are clean, clean the coil with foam based cleaner and remove the blower fan (where the majority of dirt accumulated) and give it a good cleaning. So far the air con does not give me a single problem.

    As far as I know the air con gas need not be refilled unless it is already depleted due to leaks. It is just like your refrigerator.
    what's right isn't always popular... and what's popular isn't always right.

    You're abolutely right. A fridge does NOT leak that easily and any fler telling you that it needs top up gas is hogwash!. The fridge not very cold obviously needs a through cleanout, or the cycle timer has gone kaput is most common.
    Overloading a fridge will also reduce its cooling efficiency.

    jericho is right. Got to do regular cleaning of the air filter at least every 3 month and you'll know the difference when you on the air cond is cooler. Those who smoke and wif the air cond on definitely have to get the air cond fella to clean the compressor and inside the air cond unit more regularly than others. Otherwise you'll notice each time when you on the air cond there will be a contaminate bacteria smell coming out from your air cond and it stinks.
    Believe yourself, believe what you can do
    Keep on going & stay happiee

    It was too late for me to read this thread - never trusted the leaflets in letterbox.

    Last week back from outstation, my room air-con provided me hot air instead of cold air after 2 weeks not in used. Call few service air-con companies, they only available to come check on Monday but I will away for few days. So ngam found one leaflets in letterbox, the air con shop from USJ3A, they able to come service at the same day on Saturday.

    After service the air-con, the air-con man said got one part spoiled liao, had to change the part. He charged RM180 if use local brand, cheaper a bit if use Thailand brand. I tried negotiating the price but refused with 101 reasons. Ok lar, no choice since weather quite hot recently. Total I paid RM180 for part change + RM140 (servicing and refill gas).

    The next Monday, called the Panasionic to check the price by providing the part number. Surprising that the part only cost RM32, somemore original part, the part quite easy to change, just unplug and plug back and they earned RM148. Then I call the air-con company that serviced my air-con before, the boss said usually for the part, they charges customer from RM80-RM90. He also surprised that so dare the USJ3A air-con shop to charge out of market price.

    Lesson learn, never called those contact found from leaflets or newspaper unless recommended by someone.

    Fully Agree Never Call From Drop Leaflets

    This isn't about A/C, but about calling service men from drop leaflets.

    Had an experience about a year ago...my friend had a break in at his office which is on the 2nd floor of a shoplot, so since I was nearby when I "happened" to call him, and being a 'kehpoh', I went over.

    As I arrived, so did a guy who my friend had called to fix the damaged grill. He didn't know who to call, so the neighbour had kept one of those card that were dropped into the mailbox.

    The guy checked the damaged and quoted a ridiculous price. My friend tried to bargain down but he would not budge. After much discussion my friend decided not to proceed with the repair with the guy.

    That's when the guy said that he's just an agent acting for metal workshop. Since my friend called him, and cancelled, he need to pay a cancellation fee.

    A small argument ensured but to my surprise I noticed my friend was not his usual self. By nature he is quite firm and can be aggressive.

    He finally paid him 50 bucks and when I asked my friend later 'how come?' He said based on the conversation he had with the guy, he felt it would be cheaper in the long run to pay the guy off and be done with it. I got the drift. I was in his office helping the staff check damage while all this was going on so I didn't exactly hear what was said and anyway my Cantonese not that great.

    Try Vinco at USJ9 Business Centre. Call Ivy at 80235007. They're open today. Bought my air con from there some 10 years now and is still in good working condition.
