Intake meaning the outdoor unit
no, the intake is where the filter is...the point where it sucks air in on the inside of your house.

When your AC is on, the air exiting the vents should be around 58-62F. Typically, you won't get cooler than that at the exit vents with residential units.
I have a laser thermometer just for that purpose.

Freezone is a scam. The fan ain't blowing over the ice

I do too...and it had become a heck of a habit to pick it up and check the air temp pretty much every day.

Welp, I just went to check where the ice had been and it's starting to come back.
Looks like freon is the issue after all.
I am going to try to push through with the fan when I need to tomorrow and wait to get a guy on Monday.

In all honesty I would suggest running fan only for longer than you did, you may have not melted all the ice and still are facing a restricted airflow issue.

Ok cool. Might just leave the house for a bit and come back later.
It's gotta be a positive sign though that it did cool down though, right?

somewhat, it is in the 70's there right? just open a few windows and turn on the fan for a few hours.

Yeah mid-upper 70s

If you see ice the system is starving for air or refrigerant. Period. It usually takes hours for a system starving for refrigerant to freeze; whereas, a system starving for air will freeze much quicker. This is a sealed system so if it's low on refrigerant that means it's leaking. I bought a drum of R-22 for $70 20 years ago. In May: $500. In July: $750. If you recharge a leaking system with R-22 (DuPont patented the name "freon") you are throwing money away.

It's your freon being low causing it to ice, simple solution is to gas it back up. But the big question is why did it leak down in the "Louisiana" winter since November.
Go ahead and start saving for a new unit, You going to need it before summer. Sorry

Unless the guy in November was talking out of his arse and the freon was getting low.

If it's R-22 it will be pricey. The price has been sky rocketing and they stopped making the R22 parts last year so they are harder to come by.
How many intake vents do you have? Make sure filters were installed in proper direction in all.
I would leave unit off, run a window unit. Make sure no ice on outside line. Then turn on unit. Put a box fan blowing air into your intake filter. This increases air flow.
Go to Lowes. Buy 3-4 cans of coil cleaner. Take off cover of AC unit and wet it with water hose, no pressure washer. Then spray on coil cleaner like mad. Let it soak for 20 min and rinse off with water hose. Then button the unit back up.
Go up in attic, look for coil up there and vacuum with a shop vac.
Look for drain line that ties in underneath bathroom sink. Pull it out and stick shopvac in it to clean out as well.
I'm guessing your system is really clogged and needs a thorough cleaning. Usually what happens with a terribly clogged air filter. Have a guy come out with the really heavy duty chemicals to clean the coil in attic.

this was the case with my unit a while back. I had to add Freon once a year before the cooling season...then the leak got a lot worse and I needed more only a couple of weeks after filling it. at a couple of hundred bucks per fill, you can't do it too often.
once it was leaking down that quick, I decided to go ahead and replace the whole unit instead of only replacing the evaporator coil.

I think the going rate is around $85/lb of freon. The cost is rising each quarter as well.
How many tons is your unit? You will need 2-4 lbs of freon for each ton.
If it's low, there is a leak. Don't throw away money by just keep adding freon.
But I'm guessing it's a clogging issue

In Atlanta I'm charging $125/ lb today and it's gonna be more than that this summer. 90% of the leaks I find are in defective Chinese copper tubing. So it's not going to last. And then you're right back to this same spot again. How long are you going to own that property?

And that's not as bad, right? What makes you think this is what it is?

I'm not an AC guy but it's common in rental properties where tenants don't change filters or do anything for years.
I feel your pain though. My AC unit is R-22 and 21 years old. I change filters every 3 months and a AC technician comes out and does service checkup and cleans coils, etc...Every March for $65.
