Air conditioning not cooling, not necessarily lack of snow kinds. To check the evaporator and condensing gambling is not dirty, one trick is to see whether there are drops of water outside on copper screw cap, if there are drops of water, as evidenced by the air conditioning inside the refrigerant; drops, can further check whether the air conditioner with something to block, such as the security net, the iron fence will affect the air-conditioning cooling effect; exclude the above reasons, you can see the air conditioner cooling plate dust. In addition, if long-term within the machine has not been cleaned, will also affect the cooling effect. Aging or overload causes voltage instability can lead to ineffective air conditioning and refrigeration. 

 How to solve this problem? That the key to these problems is the cleaning and maintenance of air conditioning can not keep up, the public use of air conditioning in the bedroom, room closed, people can only absorb indoor breathing into many turbid by the air conditioner after repeated filtration indoor air, negative ions will be gradually reduced, affecting the body's normal physiological function. Air conditioning evaporator of the indoor unit for long periods of cleaning, a variety of adsorption above the dust and dirt will become a breeding hotbed of bacteria, viruses, fungi, blowing through the room with the air conditioning running, air pollution, health impact, while the outdoor heat exchanger long-term in the outdoor sun and rain, clogged with dust, but also to the thermal efficiency is severely reduced, shortening the life of the compressor, the air conditioner load increases, the failure rate significantly, so the best way is to thoroughly dry cleaning for air conditioning. 
 Air conditioning with a thorough cleaning? Let's start talking about the air conditioning works, air conditioning, it has a vacuum cleaner-like effect, taking the indoor air, and then blown back to the indoor bi-directional ones wind multi-photocatalyst and dust in the air, in addition to larger particles are adsorbed on the filter online, the smaller dust, germs, stay in a small indoor unit fin gap, fin internal wet environment suitable for bacteria to survive and reproduce, the air conditioning work in a confined environment, indoor air is constantly absorbing the body's metabolism , carbon dioxide increases, so the cycle, the indoor unit adsorption of harmful substances in the growing, constantly blowing back into the air, long-term living in such an environment, there will be dizziness, fatigue, colds and other symptoms. This is known as? Air conditioning disease, air-conditioned odor, smell, also due to a variety of bacterial germs, dust, at play, but also brought air conditioning and refrigeration, the low efficiency of heating, air conditioning, long-term power increase.
