After the air conditioner in college students' dormitory is broken, the maintenance time may be different due to the management policy of the school, the busyness of the maintenance team and the complexity of specific problems. Usually, the school will arrange maintenance personnel to carry out maintenance as soon as possible to ensure the living conditions of students. The maintenance time may range from a few days to a week, and the specific time needs to be determined according to the arrangement of the school and the workload of the maintenance team.
