That's where I blasted mine. I recommend pinching the drain tube around the hose you're going to shove up there. Mine started firing cleaner back down it before the can emptied. Have a container of some sort to catch the stuff that comes out of it.

Did the cleaner today and was a bit underwhelmed, but I suppose it’s a good thing when a ton of disgusting gunk doesn’t come out of your HVAC system. To anyone considering this, I’d say save your time & money for something else unless you’re having symptoms like A/C odors or a blocked drain.

5/16 I believe. I used a barb connector and hose clamps to connect the two lines.

I used this kit on Saturday and the draining fluid looked a little yellow, just like in the photo above. There was a strong ammonia smell from the foam, so I think it is meant to be only an antimicrobial agent for treating musty smells.

The second can, which one is instructed to spray 45 seconds during three different vent settings, only lasted for two 45 second bursts. Reduce the spray time to 30 seconds if you want to use it for all three vent positions.

This kit completely eliminated the musty smell from my AC system. For how long? We'll see.

Here's Toyota's video on how to use the two can kit:

Thanks, let me try some tubing I found in my garage. If it’s not suitable, I’ll definitely take you up on this.

Thanks for the heads up. I wondered whether it would be enough after watching that video when I bought the kit.

It’s interesting as well that the video instructions differ from that was on the foam can. The video says to do it in half can increments (guesstimating what half is I suppose) while the can says to fire off the whole can. It didn’t seem to me that is much liquid drained out as foam went in, but there’s no way to know.

Once the foam reverts back to liquid the volume would be much less.
