Larger copper line on my outside AC was frozen yesterday...advice?

Wife called me and said it's only getting down to 78 degrees (thermostat was set on 73) in the house. Went check the outside unit to see if fan was turning (it was), then I checked the lines and noticed the larger of the two copper lines was frozen with ice. My father-in-law said to turn of the AC at the thermostat asap, then turn only the fan on. Her said this would melt any ice on the evaporator coils on the inside unit, which worked. I went out about an hour later and the ice had melted off the outside line. I also went in the attic and noticed a small amount of water in the drain pan below the unit, so I'm assuming the inside unit had ice on it too. Any idea what caused this? Should I get an AC guy to come take a look...I know I will get raped if I have to call an AC guy out, so I'm prepared lol. TIA
ETA: Over the course of the last 6 month to a year...we've noticed that the AC (which is a 4 ton unit) has always had trouble cooling the house below 73-74 degrees.

Take a blow dryer to it to thaw it out

Leak in pipe or low freon. Bust out about $800 and get that fixed.
ETA: Also, turn it off. Turn fan on if you want but keep the compressor off and let it thaw. They can't work on it while frozen.

Get rid of your AC you pussy. A true man doesnt need one

Just turn the unit off for a couple hours and it will defrost. Your system is low on freon, probably have a leak

Your low on free-on hoss

You are low on freon or the newer replacement for it. May have a leak in the coil.
Edit: yes call AC technician.

Sounds like you need a new unit

You are likely low on refrigerant and likely have a leak somewhere or poor airflow.
Airflow problem you can fix:
Have you changed your filters lately? Make sure all vents are open and the return is not blocked.
Low refrigerant means you are calling a tech.

How many square feet is your house?

Mine was doing something similar, it was the fan relay switch, a $25.00 part.
AC Man fixed it and added 1 lb of Freon for a minimal charge of $407.50.

3 things it could be:
-Dirty filter. Low air flow.
-Clogged condensation drain pipe.
-Leak of the refrigerant.

How old is the unit? I work around the AC field, except with chillers for commercial and industrial applications. All the guys that make big units (Trane, Mcquay, York) make splits for home ac and there is a huge difference in quality in the last 15-20 years there. If you have a 20 year old ac from a brand you've never heard of, it will run forever and need little maintenance. But a 5 year old Lennox or Carrier is essentially a piece of shite.

If the line outside is frozen then most likely the A coil inside is frozen too. Turn off the AC and let the fan run & it will defrost pretty quick. At a minimum you need refrigerant , which means a leak somewhere. Leak detection can be costly. I'd just make sure it has the proper amount of refrigerant and let her rip. It might buy you another year of needing a new coil or possibly entire new AC unit.

advice?
Probably low on coolant.
Turn it off
Have an HVAC person come out to clean your coils and top off the coolant.
