I live in an older house with central a/c in the attic. Over the
years, I've religiously cleaned out the drip pan so it wouldn't
overflow and drip through the kitchen ceiling. However, this year has
Even though I've done the bleach treatment and cleaned the pan with a
wet/dry vac, the drip won't stop and the kitchen ceiling will need
major repair. I called my a/c repairman, who blew out the drain line
with CO2. But he said that the only permanent fix would be to move the
a/c unit up off the attic floor, so the drip pan could be elevated for
better drainage. And this would cost me about $1,500.
Since this is the only time in nine years that this has happened,
isn't it a better bet that a) the pan is leaking, or b) the house has
shifted, and the pan has somehow gotten un-leveled? Granted, having
the a/c unit right on top of the drip pan probably wasn't the smartest
move, but I'm not an expert. Any suggestions, or would the a/c experts
reading this need some photographs of the setup?
B) happened here altho it wasn't actually the house that settled but the
support frame upon which the A/C unit was sitting.
A) is certainly a possibility.
It should be possible to determine from where the water is actually
leaking I would presume, even if took adding some food dye as colorant
to see the new traces emerge.
The drain _is_ verified to be open, I presume?
No frankly I think the A/C guy is right. Maybe someone else can
come up with a different solution, but it sounds to me that it was a
bad install and the only real fix is to correct the initial problem.
Otherwise you can expect repeats or you will need to be very diligent
about cleaning and noticing any problems.
You may be able to add an alarm to alert you if it gets blocked.
Question, my drip pan goes under a unit incase the pan under the
condenser inside the unit overflows from a clogged hose, do you have
1 or 2 pans, I have 2, the bottom one has a float cutoff switch so I
cant ruin my ceiling. Have you looked at the pan under the coil. 1500
to raise a unit, get bids it cant be more than 3-4 hrs work Im
guesing. But isnt the level of the AC the real potential issue, have
you put a level on it, its not supposed to be level but my installer
said raised a bit on one side so it will always drain. I think you
should try a different tech , the 1500$ aproach is not where you
start. If you dont have a second pan with float switch, get one. I
have had no issues this way
The pan is probably metal and they do eventually rust/leak.
You should have two drains, the pan thingy is the emergency water collection
Anway, HD sells a plastic pan, normally used to place under a washing
machine, that may work admirably. I replaced my metal pan with the plastic
one and connected the drain line (which runs to the soffit) and all is well.
Asked your A/C man if as float switch would solve the problem. There are a
number of different switches that basically senses if any water is in the
emergency pan and if there is it will shut down your A/C so no water will
drip out of the pan.
