Air conditioning maintenance

1, maintenance before startup

Usually, household air conditioners are turned off in September, turned on in May and June of the following year, and stopped for more than half a year. Therefore, before starting the air conditioner, it is necessary to conduct a comprehensive "diagnosis", check whether there is any "fault" in the air conditioner equipment, and do a good job of maintenance and cleaning under the guidance of professional and technical personnel according to the inventory results.

2. Maintenance after downtime

It is a perennial law to turn on the air conditioner when the weather gets warmer and turn off the air conditioner when the weather gets cooler. Pay attention to the comprehensive and detailed inspection of outdoor units and indoor units before the air conditioner is turned off. Maintenance, maintenance and cleaning should be linked one by one, and cannot be separated. Leaked links should be fixed and strictly checked. After the above steps are completed, cover the air conditioner to prevent dust pollution and prevent the air conditioner from dripping into the water.
