There is no condensation coming from my A/C. I live in south Louisiana and the humidity is high here. Had it checked by a professional who said everything INCLUDING FREON was fine. The house does not get more than 10 degrees below outside temp. I keep the filter changed. The compressor is fine and there are no obstructions around the outside unit. The unit runs constantly and performed well last summer.

Ok, after reading these answers, I want to set a few things straight.
If you do in fact keep a clean filter, than you should not have to worry about the Evaporator coil(inside coil attached to furnace or air handler). It is possible it is dirty if this were the case though I would expect a ball of ice and an icy suction line outside. And if somebody were to clean this coil I would hope they would not use an acidic cleaner.
It is possible the outdoor coil is dirty this is the Condenser coil. This can be cleaned with a garden house and nozzle. You will not hurt anything, just make sure it is very clean.
If your coils are both clean, thats a good start. You will likely not be able to check the refrigerant (freon) charge on your own, but we will trust your technician for the sake of this.
No lets look at your return air. This is the vent in which the air goes back toward your furnace/air handler. Measure the temperature of the air (generally very close to the room temperature. Next measure the Supply air, the vents which blow cold air into the room. A properly working A/C will give in the range of 15-20°F difference in temperature. If you have a difference in this range and it runs and never catches up. Then your heat load is too large for the A/C and you may need a larger A/C unit.
Also make sure that when you turn back your A/C at night don't turn it back more than 3°F or when you leave don't turn it back more than 3°F. That will help the A/C stay close to setpoint and not have to fight off all that humidity!
An Air Conditioner will always remove humidity before temperature, so the humidity and temp may just be too much!
Hope this helps!

It could be the valve which controls the amount of freon into the cooling coil isn't allowing enough through. You may have an obstruction in the line somewhere. If there's a filter/dryer, it may be full and need replacing. Feel your cooling coil, if you can. It should be cold to the touch. If is is, it could be dirty from dust buildup. If it isn't, I'd get a tech in to check your unit, or buy a new one. With the humidity, the cooling coil should be dripping condensation if it's working right.

Some systems have a filter in the freon line. your compressor and freon levels will check out OK, but the freon is not flowing through the line. It could be the "A" coil, in the furnace is dirty or obstructed. Your repair guy missed something. You should get a lot more than a 10 degree drop.

It sounds to me like the condenser coils in the air distibution unit are dirty. This can be cleaned with acid solution that most service men carry on their truck,If your guy did not do this it maybe time for a new service man.
this coil is located above the filter in most air distibution systems, and although you change your filter often, small particals still get through. If you smoke or cook in the house this also contributes to the clogging of this coil. This coil is where the air is cooled and moisture is removed before it recirculates throughout your house.

Maybe it's your house. Sounds like the air conditioner is doing it's best, your house may allow more warmth in then the air conditioner can take out. Could fix the house or upgrade to a larger a/c.
