I will preface by saying I have NO knowledge of HVAC so some things that may be obvious to you, are not to me.

I’ve noticed my drain pan has water consistently. I had a friend come and drain it about a month ago. He used a shop vac to drain the pan, the line, and the line that’s outside.

Two weeks later, I had water again. My dad cleared it for me. Now I am having some water stains on the 1st floor ceiling that seem to be from the air handler upstairs, I checked again, and there’s water in the pan.

What could be causing this continuous clogs?

My friend revelry also cleaned out my air handler blower, did a quick cleaning of my coils.
