Last month I bought a very quiet Tatung AC. It is really silent, for 4 pings area. I bought it for NT$ 9000 (new) at RT Mart in Taichung. It can cool down the room but it is not efficient. I need to close the door, let it run for about 30 minutes but it doesnt give you the ice cooling. Yesterday it was very humid, I ran my Tatung AC for 30 minutes, after that my room was still humid. And the Remote Control and the settings are very confusing. Sometimes it can cool the room well, other times it seems to stall. It was cheap though, I could just pay a guy to move it to some other apartment for NT$ 3000 (if necessary). A portable AC is very expensive, almost NT$ 30000.
And I have Sampo appliances, washing machine, oven and vacuum, they are serviceable, cheap, they are ok products. I have a very bad Teco dryer, it doesnt dry my clothes well and leave a bad smell on my clothes after 2 hours of running.
And I still have my noisy White Westinghouse, very noisy but it cools the room pretty fast (ice cooling). I moved it to the living room and I use it during day time. The Tatung AC is in my bedroom, it is very quiet but not efficient but now is fall, soon is going to be winter so it is alright not to spend $$$ to get an expensive AC.
