This has to do with a window a/c, not a phase unit, but there are so many hvac guys around I thought I'd ask. My 5000btu window a/c keeps freezing up somewhere, and then melting producing an *** load of water, which is pooling at the bottom of the unit. I'd like to get rid of this issue because it's spraying water out of the vents, and makes an annoying sound as well.
