Water is leaking from the central air system unit and drip down soaking the filter?

Question

I have my central air and heat unit in a side room in the garage. Recently I've noticed water dripping down the front of the unit and soaking the filters and running out on the floor. Its an older GE Gas Warmed unit, made in trenton New Jersey. The house was built in 1972, so i'm assuming the unit is that old. I recently changed the filters, so i'm sure its not them, It has 2 air filters, 25" x 20" x 1", one on the bottom over the same size hole to the sub floor, and a vertical filter to its left at right angle to it. The water seems to be dripping from about half way up the unit, and looking to become hazardous as the water runs down very near electrical wires coming into the unit. It doesn't drip right away, usually after its been running for several hours. I've closed some vents in other rooms to push more air to the bedroom at night, don't know if thats an issue. What do you suggest I do?

Answer 1

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 o*****e(it's located where the drain attaches to the pan),stick the hanger in the o*****e and remove the restriction.

While you still have the flashlight also look at the cleanliness of the coil at the return side.

Good luck.

Answer 2

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

Answer 3

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.
