Feel of the large copper pipe coming from the outdoor unit going to inside coil and tell me if it is ambient temp, hot or cold

I can't get the front cover off. I don't have the right tools. They are in my husbands car. Can now feel some cool air coming out of some vents. Unit was iced up this am. I turned it off for several hours to thaw. Has been running 2-3 hours and no ice in the unit if that helps. Also the condenser pipe is dripping.

Icing can be caused by a number of issues:

1.Low refrigerant charge

2. Dirty ac filter

3.Indoor fan not coming on

4.Indoor blower not moving enough air acrsoss indoor coil

5.Contactors burned together in outdoor unit causing outdoor to keep running after indoor blower stops.

6.Blocked return or ductwork causing restricted air flow

7.Dity indoor coil

Give me as much information as you can about what is happening and if any of above are noticeable and we will go from here.
