What to do about my Central A/C Freezing up.

In 2006 I had a problem with my central Air and heat, the A/C started having lots of condendsation which ran into the floor and then the A/C quit. I got a repairman who replaced an electrical thing on it and it started right up, worked fine and the condensation had stopped. I used it until about 2 weeks ago when the condensation started again but the A/C was working fine otherwise. I was told that the drain hose was stopped up the reason the condensation was going into the floor. I removed the drain hose, flushed it out and put a lot of water through it to make sure it was clear. When I reconnected the hose all the coils started frosting and freezing up. Cool air came out of 2 vents but nothing out of the others. Turned it off to let it thaw out, turned it back on and same thing. Looked at the outside part and it was frozen inside it. (Compressor) It was not doing this before I cleaned the hose. I have it turned off right now to let it thaw real good but don't know what else to do or why this has happened. Any suggestions?

Filters were new, vents open and 2 nearest the unit are putting out cool air and so far keeping house cool but all the other vents have no air coming out. Called an A/C place and described the problem, first I learned that the panels have to be on the A/C unit or it will frost/freeze up. That problem is solved. Asked why all the vents weren't working, could be duct work loose, which mine aren't or something about water down in the unit and something causing the fan not to turn at full speed which I think is possibly my problem. Question now is what to do about the water and getting air through the other vents. Any comments on this? Thank you.

Still having problems not getting air through all the vents except the two, was hoping someone might have an idea what happened and what to do to get air through the other vents. Vents are open, duct work up, filters new and it happened after the condensation problem was taken care of by clearing the drain hose and then it quit putting out the air. If it is a water problem where is the water and can I get it out? Any suggestions? Thank you.

if evaporater coil is froze up air can`t get thru to blow out your vents,,,,if you are sure the coil is clean,,,the dirt usually collects inside the coil,,,,you have to remove inspection plate to inspect,,,,,might as well clean it anyway while you are in there,,,,if still freezing up you are probably low on freon,,,,and that (unless you are epa certified) you can`t do your self,,,,,,call out the pro`s

Ok, tell me where to find the evaporater coil, I see nothing freezing up now that I put the front panel on. It seems to be working and putting out to cool a 7 room house. I found another vent putting out air in the middle of the house on the same side as the other two. Where do I find the inspection plate? I am a widow and having to check this out by myself and appreciate all the help I can get. As of now there is nothing freezing up that I can see but one piece of the duct work is laying in water that came from the condensation problem I had, could that cause a problem? It is just good and moist, nothing deep, on a footer under the house. By the way this is a doublewide, I checked all the duct work and it is up.

ok,,,lets back up,,,if its not freezing up anymore,,,lets not worry about cleaning the coil right now.,,,,,,,,,back under the house,,,,,did you check the duct work with the unit running? a lot of double wides have a plastic like liner covering the insulation under the flooring and maybe hiding a lot of the duct work,,,,,if this is your case it would be hard to see or feel the air going to the wrong places

The door has to be in place for it to work right if its not a gas furnace. On a down flow mobile home electric unit the blower sets below the A coil so the unit door has to be in place while running the A/C system or it will freeze up every time.
