routine maintenance
Regular maintenance is an important measure to ensure the normal operation of central air conditioning, including cleaning the filter screen, checking the refrigerant pressure and checking the wires.
Treatment of fluorine leakage
If the central air conditioner leaks fluorine, it will lead to poor refrigeration effect, so it is necessary to find professional technicians to replenish refrigerant in time.
Clean the pipeline
If the central air conditioning pipeline is not cleaned for a long time, it will produce pollutants, which will lead to problems such as small tuyere flow and insufficient air supply. It is necessary to clean the pipeline in time.
change a part
If the central air-conditioning components fail, they should be replaced in time to avoid more serious damage caused by long-term use. Common fault components are capacitors, fans, compressors, etc.
Check the circuit and controller.
The circuit and controller of central air conditioning are vulnerable parts. Check whether the line connection is loose and whether the controller works normally.
Cleaning evaporator
The evaporator of central air conditioner will produce dirt after a period of use, which needs to be cleaned with cleaning agent.
