how long auto air-condition freon in no fixed time, generally when the automobile air conditioning refrigeration effect becomes poor, you can check whether the freon is lack, it is necessary to replace or add.
auto air conditioning users, more than half a year to see the car machine pipeline joints and car machine outside the valve if there is a clear sign of the spill. If there are any obvious oil leakage, suggests that the machine has a leak, fluorine miscibility because oil, the oil will leak fluoride, fluoride will leak leakage. If you don't to supplement or replace cold media, to cause a decline in air conditioning refrigeration effect, it take long to refrigeration.
air conditioning normally open after a period of time, was cold wind blow to the body, and can quickly reach the set temperature. Outside of the compressor can work for a while like a refrigerator to stop for a while, suggesting that is normal, otherwise you may need to supplement the refrigerant.
the quality of refrigerant, can guarantee 2 - 3 years service life and quality of refrigerant on the market at present the good and bad are intermingled, the owner must choose normal refrigerant, quality guaranteed. Use fake refrigerant, a period of time can refrigeration, but long-term use, light produces refrigerant leakage, air conditioning refrigeration harmful situation, serious can lead to strain air conditioning compressor.
