after the air-con system in my home broke down a few months ago, i have been sleeping without air-con every night.sleeping without air-con really save alot of energy. each month we just saved $100+ from our bill from the original $300+.

i am very happy about the new air-con system. within 5 minutes, the whole room is freaking cold at 24 degrees-c. it comes with 4 ticks, thus saving more energy. i am contributing to the gaia project.. =D
