Drain suction on A/C condensate line

My AC drain hose will not drain until I take the fitting off the furnace, then it pours out. Hoses/lines inside house are not clogged. Air will also blow out where hose connects. Water then leaked out behind furnace. It seems if there was no hose attchment everything would be fine. Thinking of using a funnel to collect condensation and attching hose to that, but there has to be a better way.

Welcome to the forums.

Depending on where the drain is located on the unit there may be a vacuum on it. A trap is installed in the line to allow the water to drain with being affected by the internal vacuum of the air handler.

As mentioned.... post a picture or two of your setup..... How-to-insert-pictures.
