家里的中央空调，原来工作好好的。今年好像不工作了，请大家出些检查和修理主意。 先谢谢了！！！

问题：所有地方（包括，控制器，室内和室外Unit）都似乎设置与工作正常。就是吹进屋的空气不够凉，室内的温度一点也降不下来。

自己检查过：
1）室外Unit 排风正常，但风不是非常热。
2）室内外个管子，看着正常，无冰霜。
3）室内外之间的金属管都不非常冷（据说，应该一个冷，一个热）。

You may have to call for help now. You already did all you can do. Only thing left is to check is freon pressure. By Canadian law only licensed technician can recharge them. It may have a leak somewhere.

Do you have any suggestion for the repairing company? Anyone asked to repair central AC?

Thanks
