1, insufficient freon will not only make the air conditioner unable to cool, but also make it unable to heat. First, find out the reason for the lack of Freon, then carry out maintenance and add Freon. If freon is consumed during normal operation, just add it. If it is the leakage that causes the lack of freon, it is necessary to make up the leakage.
2. The air conditioner is too dirty, which leads to the blockage of the pipeline, which leads to the decrease of heating and cooling effect. Clean the air conditioner regularly, especially the filter screen to ensure that it will not be blocked by stains. In addition, all aspects of cleaning should be carried out to ensure the operation effect of air conditioning.
3. The power supply voltage is not enough, which makes the working efficiency of air compressor and other components worse, and cannot guarantee the cooling and heating effect. First, check the power supply voltage. If it is not within the normal range, you need to contact professional workers for maintenance.
