A/C Freezing up

[Kahoneys]

Our main AC unit woke me up yesterday morning at 2am and was dripping water down from the intake vent. I turned it off and turned on the bedroom AC to finish the night. Now it doesn't seem to blow cool air. Is it low on Freon or whatever coolent? Is it something that I can fix myself or should I take it to a service center?

Try running it with the high fan only until it thaws out, then see if it’ll run again. If it does, run it on high fan, not low or auto. You may be in a high humidity area causing the freeze up if you’re only using auto or low fan speed.

Filters dirty?

Maybe the coil is dirty?

Not sure if that is the right name of the part but our home unit was freezing and had to have the coil cleaned.

Every time I’ve had a unit freeze up it was due to low Freon. Typically the A frame coil inside was frozen.

Froze my home air conditioner once because I had closed a number of registers in an attempt to get more airflow to certain rooms. The evap coil needs a lot of air flowing across it to prevent freezing. By closing my registers I had reduced the air flowing across the coil.

In any event, make sure the filters and coils (evap and condenser) are clean and you haven't closed a bunch of registers if you are feeding them. Fan should be on high during your testing.
