In Chongqing, the air conditioner does not cool the master said there is no fluorine to the transformer burned out to change a transformer plus plus fluorine spent 550 (he said to add nine fluorine) expensive? This statement is not very reliable, why? I'm not sure why, but I'm not sure what the transformer has to do with it.

Now is the high cost of labor, the cost of fluorine will not be more than 10 yuan, depending on the region, the charge of 100 to 400 yuan are considered normal; as for the transformer damage, the cost is not too expensive, by the way, you can also be replaced, if the replacement of a separate charge of 200 or even higher is not a problem.
