Little residential hvac help please. Newer unit leaks water once a year.

It seems like years back the A coil drains were smaller and metal and clogged up all the time. Newer models have bigger plastic drains, that don’t seem to clog up that much. I usually just run clear plastic hose for a drain so I can see if it is draining. I use a hose barb fitting and a clamp on the furnace. That way I can take it off easy to coat hanger it.
