Because one of the following: inside blower does not work, or too slow, or the inside coil is dirty, filter dirty, or low on freon.

There's also the possibility of a regfrigerant side issue (bad TXV, clogged cap tubes, etc) but those are rare. More likely one or more of the issues clocert mentions.

If the filter is really dirty, then turn the system OFF and turn the Fan ON. Leave it in that configuration for a few hours, go get a filter, and then start it back up. That'll get you through until you can contact an HVAC company to come in an clean the blower system and evap coil, since most of the time if your filter is dirty, the blower and evap coil is going to be dirty as well.

You mean the evaporator right ? That's the coil that is cold. Anyways a couple of things could be happening. I know this sounds kind of stupid but you have to move air, meaning if you do not pass enough warm air over the evaporator coil it will get colder and colder until it turns into a block of ice.
There are many reasons this can happen. Sometimes something is blocking the cold air and it loops around and goes thru the evaporator again without warming the evaporator. Could be something as simple as a clogged filter. Also if the room temp gets cold like around 65 or lower for an hour or so this could freeze up the unit, when you come home room could be 90 degrees when you left in morning it might have been 75-80 degrees.
Just my 2 cents...
