A/C question

Recently Ive been having an issue with my A/C. If I run it everyday,or atleast when the cars first running it will always blow cold. But if I have it turned off for a day or part of the day while driving, it will blow warm.

An example is yesterday. The day before I drove it with the windows down. Then yesterday when I started her up in the morning it blew warm. I let it run for a few minutes, then turned it off and on repeatedly, still warm. During the day I drove it various times, and all day it would blow warm. I also noticed that when I turned on the A/C the A/C clutch would yank on(causing the car to lurch) and make a shrieking noise for a couple seconds as it tried to gain hold of the hub. The A/C compressor and clutch were replaced last August. Well this morning I start her up and the weather is whole lot cooler outside, well as soon as I turn the A/C on it cools down and starts blowing ice cubes.

I'm thinking its a faulty low pressure switch? any ideas?

Maybe its running low on Freon ???

Have you checked that for starters ??

Im pretty sure it has a good charge. The system was checked for leaks by a mechanic after I put the A/C compressor on last summer(that doesnt mean a whole lot though,especially a year later). When it works it almost instantly gets ice cold, which also led me away from that assumption. But I guess thats a starting point that should be checked anyways.

Thanks for the input

The clutch of the compressor might be going bad. It sounds like it tries to engage, and sometimes does, but other times it doesnt. Does it have a warranty from when you had it replaced.
