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?

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?

Stop nitpicking, I'm just trying to make it sound simple. cool2.gif

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.
