Not sure what's wrong with your A/C, but I've had two issues this year so far.
My fan stopped working. My A/C guy sold me a "used" (hardly) universal fan motor. Took a night to install it, but not bad for $10.
Now the Compressor isn't turning on in the middle of the day. You can check if this is the problem by hosing the compressor (within the outside fan unit) down with water. I just put up a pop up tent and it's working great. Not a long term solution, but I am going to build a better "cover" for it soon to limp it through to the winter when my A/C guy said he'll do the install for parts only as a favor to me.
