I have a 6 months old LG 1 hp air conditioner ICE RH10 (purchased from Best Denki) in the room. It could never make my room cold unless i leave it to run 6 hours minimum to run at 18 degrees maximum fan speed.


I called LG Dream Service 180082282 5 times and they come out with excuses that all airconds are the same and my room is too big. I asked them to top up the gas and it felt cool but lasted about a week then back to awful cooling performance again.


Before I had a Toshiba Daisekai 1 hp for 5 years and it gets cold after half an hour of running at 18 degree maximum fan speed, then had to turn the temperature to 24 degree, otherwise too cold.
Unfortunately I had to replaced it after an air conditioner servicing man(Jason) fouled up the machine during his acid wash and cleaning. It develop noises also.

The room is about 15 ft by 10 ft. The piping are wall concealed to the compressor outside.


What could be wrong?

Should I go for another air conditioner brand?
If so, which model is known for really cold air conditioning?

Hitachi 1hp deluxe model has the highest cooling capacity in it's class.

something wrong if need to top up gas , may be your piping or joint connection or the air con itself....

agree...

usually dont need to topup gas one..

if need to topup gas means there is a leak...

another thing to consider is the thermal difference... for the outdoor unit.. *for those that really understand AC systems*

Lots of problems possible aircond not cold.

1. Dust and blockage
2. Coolant leak
3. Your ducting, which is copper tube wrapped around some spongy rubbery insulation is broken and since your cold air need to travel from compressor outside back into your room, the cold air is lost amongst your walls.


1,2 not very likely because your aircond is new. Why don't u ask an air cond service person to check it up?

Cool air travel from compressor to room??? What kind of air con system u have:) 1st time heard this

Stop nitpicking, I'm just trying to make it sound simple.

Not too many would understand the evaporator and compressor working endlessly to transfer heat out of the system you're cooling. So it is basically cool air comes into aircon from compressor, and hot air goes out to compressor to be vented.

may be you need to get a 1.5HP air cond. If still cannot get cold then most probably is pipe leaking.

For a small room like this 1hp is more than enough. Request that they get another aircond service man to check from Lg. Waste money buying another one when it can be repaired and 6 mths is under warranty. If they are giving you the same excuses tell them to join this thread and come argue with us. If it is really true then LG aircond cannot match most other mades 1hp to 1hp in performance and you know it since you had use your old one.

Thank you for the replies. Happy new year to all here.

Today, LG Dream service came to check. They said gas was at 90 and too high. So they level it off to 70.
Then they took a pen and reset my remote control. They said air conditioner is working well. After finishing their work, I invited them to another room, similar size with same windows coverage but with more sunlight shining as it was morning. They were surprised and one said they can immediately feel the difference when the door was opened for them to enter. It was a Toshiba Daisekai 1 hp running which never been serviced since new. The blower fan and filter gets cleaned by my father a few times a year and been re-gassed once since new which was more than a year ago.
So I asked them how come my Toshiba is able to make that room colder within half an hour whereas the 6 months old LG takes hours during the day to cool the room? The man with all smiles said the Toshiba is more expensive so better quality so that's why! Any truth in this?

Bcoz its LG....

Which air cond is really cold ah?

You accepting trade in? Mine still working.


My model is LG artcool 1.5 hp. Got silver body with mirror back face.
My family want beige or white air cond only because of our new renovation.

York, cooling king.

cheap and good.. except abit noisy only

ask another air cond service or installer guy to check on your LG air cond... I dun think is the air cond problem is the installation problem.

If still got problem... u can try York... lasting and very cold air cond.

Yes, fan blower very noisy on my 2HP unit. But is good.

I got a Toshiba 1hp never have problem since 199x, move from old house to apartment in 2000 and then to my present house in 2001 and now is still working. Never refill gas whatsoever. It is quiet except since this is a very old model it takes a bit longer time to start. I have a 2half hp from Panasonic it is good and cool since 2005 but the compressor is noisy since installation, service man is excellant when call to replace compressor but still no different and the Sanyo 2001 when it starts it give you a loud noisy everytime it on/off. Another Sharp is also ok silent since 2001. Of all these brands I would go for Toshiba and Sharp, you need no service man. Other brands not use before so cannot comment.

But when we look for aircond we also look for other features like if it filter air, ion, killing micor organism, etc.

I dont think LG can be that bad, i mean the aircond cooling capability, something else is wrong. Get them to show you similar model now running at other customer places or their office or get someone service man to look at it when you service other aircond. If it is true as said then there is every reason for them to replavce this unit then trying to rectify. You should write/email LG korea and request that they reply you if thier product is wayoff Toshiba. A big corp MMC will not allow their image to be tarnished and their engineer will be fired.

i think is piping leaking problem. 2 possible piping leaking:
1. out from compressor
2. into blower.

please check all connections of 1, 2.

nowaday, contractor always use cheap and thin copper tube which easy to leak/break at the connections.

Why TS want to look for others brand when her Toshiba aircon proof good and better?

Not good enough?

try panasonic 1hp inverter about rm 1.3k at sen heng

for me it's really cold and silence. not my LG 1hp and haier 1hp b4.

fully satisfied with the panasonic inverter
