water dripping out of ac vent

With ńC. Running we have a dripping of water inside.
Its coming out of celing ac vent. We have no leaks when it rains just when running the AC.
We have three roof AC. Today Im will run one at a time to see if its one or more.

Why is this happening and how do I fix the problems.



Thanks.

Kenny

More than likely you coil is freezing up. Check and see if the probe has come out. Looks like a thermometer that is simply inserted into coil. Drop your filter and look up inside. The coil, radiator you see is what I am talking about.

If it's there, then other reasons for freeze up is low air flow, dirty filter. Low on freon, replace.

Could also be, the outside drip pan drain holes maybe clogged letting water build up and overflowing into inside.

Do a little testing and get back to us

Agreed, even with a normally operating system, if the drain is plugged the water from condensation will overflow the drain pan and run inside.

Agree, most likely the drain holes in the pan at the bottom of the AC unit are plugged. To best clean these out, get on top of rig and remove the plastic AC unit cover, probably has 4 screws with washers holding it on the unit. Life cover off and look in the pan below the radiator. You should find 2 or 4 holes on the outer corners. These are sometimes difficult to get at. I have used pipe cleaners that I can bend to get the holes cleaned out.

The coils are frozen due to lack of air flow. Turn the AC off and while the coils are thawing, clean the interior intake air filters. Open the AC dump louvers if available upon restart for 30 minutes.
