Finally My Aircon is Fixed (I Hope!)

Yesterday those Gain City guys came again, did the welding thing, but this time,  they opened up the compressor and took out the mainboard, the guy said there's a leak inside, so he went on to plug it, he took more than an hour. After the servicing, it worked well yesterday night. Today when I came home, I was expecting the worse, I thought the aircon will probably stop working again and to my surprise, it's still alive! I hope it doesn't break down again...
