AC condensation drain line question

[Golfer Guy]

I have a clogged A/C condensation drain that is now leaking onto my bed from the bedroom A/C unit. Where that drain line penetrates the roof there is a "T" in the line. I don't know why there would be "T" and am curious if anyone knows why and what the now two lines are for. Obviously one is the drain. What's the other line for?

Hopefully the picture is attached.

Thanks for your help.

Is there a best way to unclog this drain?

My guess is that one drain is for the evaporator coil and the other is for the overflow pan similar to what a home AC unit would have.

I have used compressed air (set at lower psi) to blow the lines out. Take the lines apart at the T and blow all the lines out.

Ac should have two small pans, one on each side. Your t connects the two.

If clogged use the plastic line from a string trimmer ( weed eater ), stiff enough go through a plug and flexible enough to go around a bend.

Thanks for the input guys. I will tackle that project shortly.
