Any recomendation for a competent AC guy in BR

I know you cleaned it but Really just sounds like your drain is clogged or has algae in it…..do you have a connection that you can take loose?

Sounds like the main problem -stoppage - is between the primary drain pan under the evaporator coil (inside the air handler or boxed coil, not the emergency secondary drain pan you are having to empty) and likely the vent tube in the condensate drain line you are pouring bleach or hot water into - in other words, the blockage is upstream from where you are adding bleach.

Any HVAC tech will blow that out with a CO2 or Nitrogen, or cut the condensate line and vacuum it out, then add some anti-algae-slim tablets inside the primary drain pan. That typically something they will do with a scheduled annual HVAC maintenance service if you want to look into that going forward, but also a pretty easy DYI project you can do once or twice annually once you know/see what to do.

sounds double trapped

Call Bitter Heating & Air and explain the problem to them. Tell them you need someone to see why the pan keeps filling, not why it isn't draining.

I have had nothing but positive interactions with those guys.

The only other suggestion would be to clear your plumbing stack. That would usually be a plumbing issue, not sure if an AC company would do that.

I added a female hose spigot to it with two ball valves and cut one off to force water out the other one to the sink or wherever it drains.

Did you do this just before the issue started? This could be the problem. Try switching it back to where it originally drained. And why did you do this?

Can you submit a pic or drawing of this?

Also, does your drain line justpast the AC unit have a pipe straight up that you can pour liquid in? If so, is the cap off? If so, put the cap back on.

No I did it after the problem started as a means to blow the line with water pressure. Before I did it it was the drain line and it had a T with a removeable cap installed originally by the ac people ten years ago.

I added a hose spigot at top of the existing T, and added a ball valve before the T to block water going back into unit (and bleach too). I am really tech illiterate and have never been able to post a pic here.

Assuming it's a pvc pipe, you might be better off just buying some from Home Depot and replacing it. I've seen some lines get so thoroughly gunked up that it wouldn't dislodge.

It's a very easy project.

Could also be your roof sewer vent that the drain line ties into. Can run a water hose down that pipe and flush it out.

Have you tried an enzyme treatment for the drain?
