Still smell the air cleaning
Performance: "I'll wash myself before coming once every summer air conditioning is the fear of unpleasant smell, but not for a long time after this cleaning, find air conditioning or smell, air conditioning useless for a long time, is it going to change?"

Diagnosis: "odor generation, mostly due to the accumulation of air conditioning condensate pipe, forming a dark and humid environment, making the mold reproduction, light cleaning is palliative approach should find the problem from everyday driving habits." service department official said, a lot of people used to wait for parking was off the air conditioner, this will cause condensation deposition in the pipeline, the condensed water and airborne dust debris attached to the evaporator surface together will breed a lot of bacteria, with the wind blowing contaminated air-conditioning throughout the interior air. Therefore, the best in destination thirty-five minutes before switching off the air conditioning compressor, the fan idling, due to increase air flow, parking in front of the temperature rise inside the air conditioning ducts in order to reduce the generation of condensate, dry air-conditioning system.

Air conditioning and refrigeration effect is reduced
Performance: "There never used air conditioning six months, the weather is hot every day, every time after the start of air conditioners, will be long before refrigeration and cooling effect simply is not obvious, and there is no air conditioning around the abnormal situation, is a quick return thing? "

Such abnormal sound is generally due to the refrigerant composition of air and water caused by doping. If the situation remains the same after adding refrigerant, which is located near the compressor abnormal sound position, then the compressor internal mechanical structure damage greater chance; If abnormal sound relapse after a period of time, and is located inside the center console, then dried to reduce the chance of bottles efficiency larger. After successive investigation, find the key issues in order to remedy.

Open air car difficult to mobilize
Performance: "My car displacement of only 1.3L, usually I do not gnaw with air conditioning, two days before the main is too hot, put the air conditioning turned on, I think after the open, the car is difficult to start than usual, why?"
