I noticed that the condensation overflow of my a/c unit is always dripping.?
Question:I checked in the attic for a stopped up drip pan but there isn't one. I see 2 pipes coming out. One is the overflow going to the outside of the house and the other goes down to the guest bathroom sink. I took it apart under the sink and it doesn't seem to be clogged. Is something else wrong?
Answers:
Take a gallon jug of water up to the attic and pour into the condensation pan. The water will flow to the lowest point, this is the primary drain. It should be the one going to your plumbing. If the water flows first to the overflow, the crew that installed the unit hooked it up backwards. You can leave as is, or switch the lines.
If the water goes to the primary but does not flow, you have a clog somewhere. You might try a strong shop-vac on the outlet side and see if you can draw the clog out, or blow the drain out from the top with compressed air, CO2 or by the ole' tuba method.
Isn't that normal operation? All the AC units will have condensation and need to send the water to a drain.
Are you sure that the outside drain is the overflow and not the regular drain for the AC unit?
There has to be a drip pan under the A coil somewhere, if you think it is wrong, then find the source of the water and see where it is supposed to drain.
Good luck.
The pipe may be clogged with algae or mud from dust and water. If the pipe is exposed to light anywhere that is most likely where the algae would be.
You may have to disassemble the drain line to find the blockage.
That is Normal Operation of a Healthy Air Conditioner.
It's supposed to get rid of Condensation.
If it Didn't, then you WOULD have a Problem!!
Now, is it Leaking off of the Top??
If so, then you should pour some DrainO into the Pan, after turning Off your AC. This should get-rid of anything that Might be Clogging it up.
Otherwise, it sounds like you have a Very Healthy running A/C!! :)
