A/C unit in attic is leaking a substantial amount of water
Unit in attic is leaking a substantial amount of water from underneath where the coils are located. It also has ice forming on the outside. I have resealed all the seams with waterproofing repair tape but continues to leak. Cold air blows out downstairs and warm air blows out upstairs. Is this a freon issue?

the line can be soldered brazed or replaced ---how hard depends on access to it ---unit vacuumed then pressurized with freon [unknown size of unit ]--then tested --estimate will vary [would need to see access and amount of damage as well as age and size ]--can be anything from 250 up check with hvac companies in your area for estimate
Sounds like it is freezing up. Kind of hard to say since you did not say whether it is a central heat and air system. My overflow was constantly draining onto my patio from overflow. I crawled up in the attic and followed the pvc pipe where it came in from the outside and closer to the central unit in the attic I drilled a hole in the 90 degree elbow of the pvc and unclogged the pipe which was frozen from running so long. Then I covered the hole with silicone. no more leak coming from overflow
I assume you have a unit in the attic as described condensate leaking from ceiling and down the walls etc. What is not normal is a bucket to contain the condensate, there should be 2 lines a primary from the evap coil and a secondary preferably from a secondary drain pan resting underneath your unit. A bucket will never work in this capacity.
Hi there, I know that most units have a drip tray at the back or under the unit itself. well the older ones anyway, not sure with really new ones, but they shoukd. these trays hod water condensation and any drainage from the fridge itself. These trays sometimes have a coil in them which heats and help to evaporate the waterso that it does not overfill and spill out. these trays can become overfilled, the heating elemet can stopworking or
Could very well be.
Seems to me when they replaced the outdoor unit in 1996 someone should have found out that there was a leak when a vacuum was supposed to be pulled and held on the existing line set and and the unit in the attic for a period of time.
A known leak is supposed to be found and repaired.
find a company that is willing to spend time and find your leak.
Most likely it is in the line set going to the attic or the indoor unit in the attic behind the wall.
It sounds like to me that the leak is coming from inside the unit(air handler) possibly your evaporator coil is icing up and causing a build up of water just below where the 3/4" P.V.C. drain line connects. Instead of draining out the line, it is finding its way out of the unit else where. I have seen this many times. It sounds like you have done everything that I would have done, but take a look at the bottom of the evaporator pan and I bet that it also is starting to rust out.If the new overflow pan is not leaking, and the condensate line is leak free, it has to be leaking from the evap pan inside the unit.That's why you have the overflow pan in the 1st place to prevent ceiling damage as I am sure you know. I hope I have been of some help to you, please let me know what you find.
For original poster: Check all milky white colored (polyethelne) plastic water lines. These lines tend to get brittle and can crack over a period of time. They extend from the water valve to the ice maker, and from the water valve to the inside of the refrig to a "radiator" so the water can chill, before it runs back out the refrig, past the left side of the refrig behind the bottom grill, through a coupler, and up through the bottom hinge of the freezer door. I'd also advise putting in a separate shut off for the water supply to the refrig so you can have water to the rest of your house when you have a problem with the refrig.
For next user with similar problem: you can check the above, but it may be that the defrost drain is plugged. (on a S x S unit, it is located at the bottom of the freezer compartment, behind the back wall.) If you have a layer of ice on the floor of the freezer, that's a dead give away of a blocked defrost drain tube, Use a turkey baster with hot (not boiling) water to flush it out.
it cold be different problems.
1-check for any air leaks around the house.
2-check the return box and see if have any opening and seal the holes.
3-check the insulation on the attic or any motor that takes the heat out the attic.
4-check if the unit is under tonage each tonage mean a 400 sf per ton.
5-check if the air handler coil is not dirty and enought air going thru the coil.
6-check the pressure of the condenser unit if have the rigth presures.
7-check thermostat if is set-up right.
it's possible, like mine with the same problem, that one or more of the plastic feet under the water tank has broken, then making the tank move and upsetting the valve underneath. My one always leaks clean water, never dirty and I have a broken foot.
