The drain is plugged or draining very slowly.The best way would be to blow the drain out with about 10 lbs of compressed air.If you have none available,a close hanger may work for the time being.Shut the power off and remove the panel,witha flashlight locate the drain pan orifice(it’s located where the drain attaches to the pan),stick the hanger in the orifice and remove the restriction.
While you still have the flashlight also look at the cleanliness of the coil at the return side.
Good luck.

stop using the unit It sounds like it is the condensate line leaking. The process of hot to cold creates moisture that needs to drain away from the unit to the outside or to the nearest sewer drain . This drain usually leaks into a drip pan if the main condensate drain is clogged . From the drip pan it also will drain out. Your drain is probably clogged find the point where it exits thye unit and try blowing air through it.It should be easy to locate and easy to take apart isshould be made of common pvc pipe about 3/4 inch good luck

Look for a drain line from the evaporator coil. It should be near the refrigerant lines.
Maybe a wet vac could be used to suck out any possible restriction in the drain line itself.
The drain pan itself could be full of debris and blocking the drain connection.
You could also have a rusted out drain pan. That old of a unit would have had a metal drain pan unlike today’s coils that have plastic pans.
