AC coils iced
What dos it mean when your AC coils have a thin solid block of ice on them

Could be the coils are starved for airflow due to either a clogged air filter, failed fan in the air handler, or the coils are really dirty.

The coils were very disgustingly dirty

I was able to use a soft hairbrush (wife is out of town:)) as a coil comb

They aren't icing up anymore but I know I need to do a more thorough cleaning

I have a shedding dog and the filter has been gone since I had work done on the unit two or three weeks ago

I thought he replaced it but was merely assuming

Thats probably it... Dirt will slow the air movement and allow the condensation to build up and then turn to ice.

I have two dogs that shed plus a cat so filters gotta get changed every two months max.

Been working without the ice since about 30 minutes after your post

Glad it worked out!

Loss of air flow or loss of charge are the biggest causes of frosting/icing of coils. Try a coil cleaner like Virginia coil blaster.
