Air conditioning maintenance and repair

Air conditioning maintenance and repair, reasons for central air conditioning not cooling

1. Lack of fluoride. According to the model and usage status of the equipment, when the central air conditioning fails to cool after three to four years of operation, it may be due to insufficient refrigerant. Of course, the reason for insufficient refrigerant may be due to evaporation during normal use, or it may be due to leaks in copper pipes or pipelines. When this phenomenon occurs, it is necessary to first check for leaks and then add fluorine.

2. The number and model of central air conditioning units do not match. Some friends randomly find installation companies when installing central air conditioning, because the design is unreasonable and the installation is not standardized, which can easily lead to poor performance and insufficient cooling during later use. So we suggest that you choose a professional central air conditioning installation company.

3. The outdoor unit is too close to the heat source. When the outdoor unit is equipped with cold and heat exchange, if the installation location of the outdoor unit is relatively closed or there is a high heat source in the surrounding environment, it is easy to cause the heat emitted by the outdoor unit radiator to not flow away, resulting in the air conditioner not cooling.

4. Not regularly cleaned and maintained. Whether it is the radiator of the outdoor unit, or the filter screen and air duct equipment of the indoor equipment, regular cleaning and maintenance should be carried out. Otherwise, dust and impurities will be adsorbed on the unit over time, which will not only reduce the cooling effect of the equipment and increase operating energy consumption, but also make the indoor environment unsanitary, posing a safety hazard to the user's health.
