Air Conditioning - AC Coils on furnace leaking

Hello all:

I have a problem that just started on my furnace. I have a split AC unit (Compressor outside of house, coils on the inside on furnace). I just noticed that there is water coming out from between the furnace (which sits on the floor upright) and the ductwork that's attached to the top of the furnace. THe ductwork is totally wrapped up and I have no way of opening it up to see why it's leaking. can someone please let me know why it may be leaking? I have a 10 seer unit that's 10 years old (Lenox) and my other unit just went out. I'd like to salvage this one if possible. Is there a way to access what's inside the duct work? If I do, how do I fix it and replace the duct work as it was?

Many thanks for any assistance!

It sounds like the condensate drain line may be blocked. Clear the line utilizing a shop wet vac and air pressure or a combination of both. This happens very frequently. I think that there may be several old posts here on that subject with great info. Try that search feature for more info than you can stand.

Thank you for the reply. How do I do this? I turned off the unit and waited a bit and turned it back on and now it's not leaking?!?!? I have two pipes. I think one is for air intake the other for drainage. The drain line was flowing water when the leaking was occuring and there did not seem to be a blockage. I also noticed that my the breaker to my ac unit was off. I'm not sure if that happened during the day, but wold that cause the leaking?

Thanks again!

That does deepen the plot now my best guess would be that the evaporator coil froze over and the unit kicked the breaker due to compressor overload from liquid slugging. When a frozen coil thaws it can overload the drain system plus pieces of ice will drop into the pan and block the flow of water causing the drain pan to overflow. Make sure you have a new clean free flowing return filter and check you evaporator coils to be sure they are clean. You will need to keep a close eye on this unit to see what it is doing if you notice diminished airflow from vents take a look at the evap coil to see if it is freezing over if it is shut it down and call for service as you probably have a leak and are low on refrigerant (if the filter is new/freeflowing and the evap coil is clean and it still freezes)

Thanks a bunch! I do have a tech coming out in the next couple of days (to replace my other unit as well as to check this unit). Hopefully I'll have better luck than with the other company I just paid 100.00 to inspect my units.

Thanks again!
