I have a Ducane HVAC system that started leaking out of the evaporator coil housing. Mine looks like the EU1P. I read that i need to clean out the drip pan.
II tried cleaning it by sucking out the buildup with a wet/dry vac and flushing it with bleach solution but it's still leaking out of the back side that I can't get to.
I've heard of people hosing it out, but that seems like it might make a mess and get things wet that maybe shouldn't be. I've also heard of people blowing it with compressed air but i thought that might just blow the stuff around only for it to clog up the system again.
What should i do to get this thing to stop leaking?

I had the same issue recently on my HVAC as well.
You probably have a PVC pipe running from the bottom of the evaporator coil housing. The blockage is probably in there somewhere. You can disconnect the PVC and let the condensate drain into a bucket.
If it does drain cleanly into a bucket, your blockage is in that drain line. Either snake it out or replace it. For me, snaking a 3/4 inch PVC with several 90-degree bends was more difficult than buying a couple pieces and replacing the drain line with 45-degree bends that are less prone to becoming blocked.
I filtered the condensate where my new drain discharges into my sump with a paper towel and was shocked how much debris was being flushed out.
