I have a technical question for the group. I inspected an attic ac unit, everything works well. However cool air is coming out of a drain line, its not much air but it is strong enough to blow a fiberglass piece out of its way.
I believe it is a defect, however the building contractor along with his HVAC sub contractor say it is fine.
My logic is this, no conditioned air should esacpe the system no matter how slight, especially in the attic.
