My AC was icing up and I called repair man and he said check the filter. I did it was dirty as heck. So had it out for a week and it was running great. Picked up a new filter today and it froze up again as soon as I put it in. Any help??

Running the unit without the filter was not helpful. The dirt that would normally be trapped in the filter is now embedded in your indoor coil. If you can see the coil, gently rinse it off with plenty of water from a spray bottle. A small amount of laundry (low-sudsing) detergent in the water will help break up the dirt particles and help the go down the condensate drain.
If you can't see the coil, call your service technician and have him clean the coil.
If the old filter was clogged, most of your dirt accumulation happened prior to your new filter. If the ductwork has not been cleaned in the past seven years, schedule a cleaning as well.
Is the new filter the same type as the old filter? e.g., fiberglass, polyester. or pleated media? If the new filter is too dense, it will also block airflow.

If this is a central A/C unit, remove the front cover. Open the grill and remove the filter. Take a flashlight and from the bottom side look at the coils. If the coils or black or matted over, they need cleaning. Check the squirrel cage blower fan. It can be removed for cleaning. In the front there are two screws that hold it in place to the frame, the motor has a plug. Pull straight out and clean dirt and lint from squirrel cage. The cleaning of the coils and blower will take 3 or 4 hours, so take your time. If unit freezes after its cleaned, it is low on freon. Only to things will cause a unit to freeze up, restricted air flow over the coils or low freon charge. Units should be cleaned no less than every two years.

You could have an underlying issue here. The head pressure might be too low, like you are low on refrigerant.
Though since it ran fine without a filter it very well may be that the filter you are using restricts the air flow too much. If the evaporator does not have enough air flow it can freeze up.
Try using a less restrictive filter like the old fiberglass type. Also make sure all your vents are open.
If all else fails call a tech out to troubleshoot.

mike run a test on the thermostat dip the probe in some ice water and see if the compressor will shut off after a few minutes, if it does not then the control needs replacing if it is a central unit then thats another ball of wax. the contactor may be fried and not shutting down the system or the wall tstat may be sticking.the pressure might be low and gas added and the coils may be dirty as well.

The air conditioning itself is dirty. You've got to have it cleaned. You can use a hose outside to hose it down or a steam cleaner... but you have to open it up (take the case off) to do it really well.
I go thru this once every three months... but I live in one of the dirtiest states air quality wise (guess which one!!!)

sounds like the coils are dirty also which will have ti be cleaned by a pro . if you had the filter out for a week i know the coils are dirty !

Does it have a plug that you need to remove? Sometimes that plug can build up water, and then freeze up.

You probably need freon.
