Typical A coil 3 ton unit. Water is getting in the over flow pan. The interior pan is plastic so not rusted through. Where do the plastic pans typically leak?
Mian drain is clogged most likely. this happens most at the condensate trap. you will need to blow out the drain line from the unit side. Or suck out drain from its termination.
Where is the condensate trap located? Also, there is ice buildup on the pipe that runs from the exterior of the house to the outside unit. What does that mean?
Amy: also, might want to dig a French Drain (absorbant rocks in a hole) for that drain line if that's your main drain. If that's your secondary drain than you as well need to have your pipes cleaned.
My ac would not come on so i researched and i suctioned the pipe in the pic i got about 3gal of water out of it i also removed all water from drip pan it came bk on and is working fine now but i dont want 2 have future problems
Did you notice an electrical float switch in your drain pan? That's a good thing to have, shuts the outside unit off in the event that condensate water backs up. Prevents water damage.
It's simply a float that sits in the water and at a certain point of being lifted cuts the electrical signal off. Once you drained the water, it lowered and allowed electricity through the wire again.
I use compressed nitrogen to blow out drain lines from the unit outwards. If you have an air compressor it may work.
It's a very simple job in most cases and I'm sure you could do it yourself but I'm going to have to say that you're going to need to call someone out, assuming you don't have a tank of compressed nitrogen or an air compressor.
Also Amy, might want to extend that drain line from where it currently terminates right next to the condenser a few feet further away from it and your home. Eventually that condenser will sink due to that water draining right next it.
And it'll leave rust stains on your home and grow algae.
I had black mold growing in the plastic condensate pan used for the A coil in a previous home. Clogged the 3/4 inch condensate line completely, and affected air quality in the home. Plasticizer leaching from pan caused severe mold. I cleaned the pan and coil with bleach, water, soap and shop vac.
