Yeah! I have AC in the study, but it is really noisy, sometimes I just can't stand the noise (it gives me headache) because it was less than 1 meter above my head!!
And I can't move my computer to another position because I can't move all the heavy bookcases around (the room is packed....).
I can't just dump the AC because it is quite new and works just fine. I hate the LG AC, and I'll not buy another LG machine next time! My friend got a larger LG air-conditioner because the retailer highly recommended it about the same time I got mine. (We both asked for a quiet model but.....) Her LG AC makes such noises that she can't sleep well with the AC on.
The other two brands that I got for my other rooms are quiet and work wonderfully.
Edit: The above are only excuses though.
What really concerned me was the electricity bills (I can't give up the computer and internet usage of the electricity!) and a little bit of "green thought". The price is up now (7.5%), and will be much higher in the future (household electricity price will be up on average for another 25.2% in October, and it won't be the last price adjustment to be sure).
And I'm just trying to live without AC and I only use AC if it is absolutely necessary, e.g. when it got too warm and humid for a good night's sleep, or when my mother visited me.
Retailer that installed my AC (in my bedroom) many many years ago still waits for my call to get a new one (he told me that AC can only last for so and so years....), but since it was used so sparingly, it is still "new".
