Suction line outside freezing up, basement wet. Need recharge?

Second time this has happened in the past week. In between both times, I had the ac running for a few hrs per day, no freeze. Could use some advice.

Diagram

- Outside: Suction line frozen up to compressor
- Inside: I couldn't tell if evap coil was frozen, likely was because I went through 2 filters, they got wet on the bottom. Had to take covers off furnace unit and dry out below blower. Basement floor had water.

Today I looked in the evap coil and was clean as a whistle (just got ducts cleaned in April incl. coil). What could it be?

Low on refridge?
Expensive 3M Filtrete filters not allowing more airflow?

Thanks!

 

The problem could be either one.

 

How much does it cost to recharge my system? What am I looking at? 200? 300?

 

Install a cheap filter and see if that work. if not, check refrigerant level, may be low. cost of recharge, depends on area, amount, and firm, you may have to fix the leak first.

 

On a rental I own, the AC had the lines (don't remember which one) freezing up at the condensing unit.
The "Pro" came and looked at it and said the house needed more return ducts! He also said the coil in the handler could use a cleaning also
I had him clean the coil for a total of $175. It worked , then the next day, the tenant called and said it was frozen again.
15 minutes or less on the internet, at an appliance help sight, and I ordered a fan relay. It arrived 2 days later ($32) Took cover off air handler and in about 5 minutes had the relay changed, and it has been working fine since then.
More return ducts! Lol. It had worked fine for 10 years. He said, things change over the years.
Good luck with your problem. Check and be sure the fan is blowing in the handler.

 

Thanks everyone! Found a retired guy on Craigslist, very helpful and knowledgeable. Checked the charge levels, was low. Charged 2lbs, never felt such cold air since I bought the place. Paid $190 total.

Problem was 2 fold. Go downstairs after an hour, water EVERYWHERE! Come to realize the drip pan tube wasn't leaking much water. Turned everything off, removed tube and plastic elbow, HUGE gunk. Pulled it out, water gushed out like crazy!

Dried everything, 2 hrs later back and running. Been about 5 hrs total so far no issues!

 

It's good to be cool again. Thanks for letting us know how you made out.
