Having the fan circulate warm air through the duct system can reduce the.
Return air duct filled with water.
The return air vent openings need to be on the opposite side of the room so the conditioned air is pulled across the room.
This is where the water is supposed to exit.
Water condensation is collecting inside of return air duct about 6 8 feet from filter grille.
The most likely explanation for the water in your ducts is that warm interior air is entering the ducts during the winter and the moisture in the air is condensing on the interior of the cold ductwork.
You can fill the canal with gravel so water can move easily and can even cover the top with sod to conceal it from the rest of your lawn.
3 seal off unused a c ducts.
When water vapor laden air cools to a low enough temperature it condenses forming liquid water.
Martin holladay editor of green building advisor responds.
If the supply ducts are high or in the ceiling then the return air ducts or grills should be low on.
If the supply ducts are in the floor then the return air should be located up high.
If you still have moisture in your air ducts seal off unused a c air ducts and supply and return vents in the winter.
Also lots of cold air is coming thru return grille and travels down into main area.
This will reduce moisture in the air and prevent condensation in ductwork.
The first is to keep your ducts.
This pulls the air across your body.
This is more likely to happen when ducts located in unconditioned spaces like attics are not adequately insulated and the air in them is not circulated on a regular basis.
Once you determine these systems are working well run a dehumidifier in the area where your air ducts are collecting water.
