a-coil plugged

I run my air conditioner and water from the a-coil backs up and run all on the inside of the furnace. The plastic tube for the runoff has no water in it at all. What tool do I need to suck the blockage out? Thanks in advance.

A Air compressor also works to blow down into the line. It should have a T at the top of the line, to allow Hot water to flush it out, along with blowing it out.

If you are getting a gunked line. Your unit is most likely not running long enough after the outside unit shuts down. The one place you see this happening as a common occurrence, is in units placed in attics.
Ren: Now listen, Cadet. I've got a job for you. See this button? Ren: Don't touch it! It's the History Eraser button, you fool! Stimpy: So what'll happen? Ren: That's just it. We don't know. Maybe something bad, maybe something good. I guess we'll never know, 'cause you're going to guard it. You won't touch it, will you?

In the old days when R22 was cheap , I saw service techs blow out the drain lines with R22 .

God bless
