I don't mind as much during the winter, but summer is coming up, so I thought I'd throw this out there...

My A/C doesn't seem to work when I am at stoplights or when I am not accelerating. Air is blowing out, but it is hot air, not cool. After I have been driving for about 20 minutes, it gets colder, but during the first part of the drive, I am unbearably hot. Is this a compressor problem??
I don't have as many problems during the winter, but in the 95 degree weather, it is useless...

Also, it helps when my car has been in the shade.

I have no idea what is wrong.

go have your A/C system recharged , sounds like you are low on freon
