Why doesn't the exhaust system of property and underground garage work?

There may be several reasons why the exhaust system of the underground garage of the property is not turned on:

1. Cost: Starting the exhaust system requires a certain cost, including maintenance and operation. If the property company does not have enough financial support, it may not be able to maintain the normal operation of the exhaust system.

2. Equipment failure: If the equipment of the exhaust system in the underground garage fails, such as fan damage, pipe blockage, etc., the system may not work normally. At this time, the property company needs to invest manpower and material resources for maintenance. If the fault is serious, it may be necessary to replace the equipment, which will increase the operating cost of the property management company.

3. Improper operation: If the employees of the property management company operate improperly or fail to follow the prescribed procedures, the exhaust system may not work normally. For example, the operator may not turn on the system according to the prescribed time and procedure, or may not clean up the sundries around the equipment in time.

4. The air quality of the underground garage is good: If the air quality of the underground garage itself is good, it may not be necessary to open the exhaust system. In some cases, such as parking rush hours and traffic jams, air quality may deteriorate. At this time, the property company may open the exhaust system to improve air quality.

In a word, the exhaust system of the underground garage of the property can't be opened, which may be caused by many factors. If the owner finds that there is something wrong with the air quality of the underground garage, he can report the situation to the property management company and ask it to take corresponding measures to improve the air quality.
