Gas and Oil Home Heating Furnaces - AC Unit leaking onto floor

I read the "Water Everywhere" post but that doesn't seem to answer my question. I own a Condo on the 2nd floor of a three story building that is almost two years old. My AC Unit is located to the right of the front door of my unit. My Central AC Unit works fine but only one problem. Water continously builds up in the pan and eventually there is water on the floor. In April 2001, the drain had to be cleared and redirected. In June 2002, the circuit breaker had to be replaced and more freon was added. I noticed water in the air filter when I replaced it in June 2002. I currently turn the AC Unit off when I'm not home, turn it on when I come home, and clean any water that is on the floor surrounding the AC Unit. The floor is starting to peel up. Looks like drywall flooring in that AC Closet. Can you provide me with any information that might help me to fix the AC Unit and the floor problem? Thank you in advance for your help.

The AC Tech told me that the coils needed to be cleaned, I needed a better air filter, and the drain pipe was clogged. He used some type of spray to clean the coils, vacumed the water and drain pipe with a wet vac, and told me to go buy a better air filter and replace. I asked if this was something I could have fixed myself. He said that I should not be afraid to go over to the Home Depot and ask questions and try to fix it myself as long as I don't bother the motor. The Tech told me that I could get some coil cleaner and that I should buy a box of air filters instead of one at a time. I'm thinking about buying a wet vac as the Tech charged me $30 to vacuum up the water and vacuum the drain out. The service call alone was $69.95.

BusyBee,
You shouldn't need a wet-vac as long as the drain remains unclogged. That seems to be the main problem. Keep the drain line clear.
