What can I do about moisture coming through the vents when the air conditioner is on?

Answer by  cooldave (31)

Have a qualified technician check your indoor airflow. This should be measured in cubic feet per minute and the correct number is 400 CFM per TON of cooling capacity (2 ton system should be 800 +/- 10%). Low airflow 1st cause, low refrigerant charge or evaporator coil problem next.

Well if there is moisture coming in, then you may want to adjust the temperature on the air conditioner. If there is a lot of moisture, this could have something to do with the humidifier settings. So adjust those and also you may need to clean up the vent to check for damage.

If your air conditioner has a setting that runs the fan on lower speed, try it. This will pull more water out of the air and lower the humidity. You may want to purchase a dehumidifier.

Moisture coming through the vents could mean there is a block passage which leads to the outside. There is a cover on the outside which should be able to be removed so you can give it a clean.

Get a dehumidifier for the square footage of your area.Also make sure if it has a negative air system the filters are unclogged and not causing moisture build up.

First, check your air filters, condensation pan and pump, and the coil. All of these should be in clean and proper working order. If they are all properly working and clean, it could either be due to moisture build-up over the winter, in which case it will go away quickly, or you may need a dehumidifier in your house.

The best thing to do is to put a filter on the vents to catch the water. There is not much more you can do about it because the water is coming from the humidity in the air.

Well if the moisture is coming through the vents, then you have to ensure that your air conditioner is connected properly with your heating system.

Normally, If an air conditioner is "cold enough" (heat exchanger plates colder than the dew point for your relative humidity) moisture should collect on the heat exchanger plates, and drip down a drain hose/tube from your air conditioner. Sounds like either your: heat-exchanger-plates "not cold enough" or drain-hose/tube clogged.
