Make sure you take your car somewhere to get the A/C system purged first.

Then you would remove the condenser, fan, compressor, compressor pulley, ac belt, evaporator core, all other misc. stuff.

By searching here, I found a post where white_n_slow took his out and weighed it. It was only 38lbs.

I would just leave it to keep up your re-sale value of you car. If you don't use the A/C, maybe just remove the belt so it doesn't strain your engine. I don't think the weight is that significant.
