There is one room that the air comes through the vent but it is very weak and not cooling the room. Once the water has gone by, air is reintroduced from the vent stack preventing the creation of a vacuum. Once you have removed the vent covers, they can be soaked in in the sink or bath tub with warm water and a little mild soap. Air only comes out of the floor vent, regardless or the setting. If your cooling system was a body, the air ducts would be the respiratory system. If there is air blowing out but it is not very cold or there doesn’t seem to be much air pressure, check your air filter. One of the benefits of renting an apartment is that you have access to a handyman, either the landlord or a professional they hire. Try increasing the fan speed (which will disable the Auto), and then press the middle vent switch and see if air comes out the middle vents. All ducts leak, if you put the filter at the return air vent and have a leak between the gril. I see hot and cold going in and waste going out. These are symptoms of air pressure problems caused by poor airflow from HVAC systems. Out of sight, out of mind can't become a habit, as the systems need checked even when not in use!. Help! My a/c in my apartment keeps letting out a musty smell when the air turns on. It worked for about 30 minutes and cooled the house down.
