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

Posted on 6/1/17 at 9:13 am
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.

You have a free-on leak, probably need a new Evaporator Coil. I'm on my 3rd one in 14 years. About $1000 to change.

dirty outside or inside coils can also cause this.

Sounds like you need a new unit

Realistically, if this is the problem...how much should this cost around roughly?

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.

THIS! Years ago, I panicked and call an AC guy out to fix it. He turned the unit off and stood there with a hose washing grass clippings and dirt off the outside unit for about 10 minutes and then wrote me an invoice for $120. Didn't have another issue for a few years.

Make sure your drain line from your pan is clear, and free flowing. If not as it thaws out it can over flow the pan, and do damage to your ceiling.

How many square feet is your house?

Latter implies the former, with "pipe" usually being the evaporator coil, which will need to be replaced. (Freon is not consumed; if it's low, you have a leak somewhere, or somebody stole it.)

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.
