New A/C compressor did not fix problem
In NYC the heat is unbearable. I drive a ford f250 with a manual transmission. I was looking to make my life easier and these are the chain of events:
1. Topped up ac with refrigerant.
2. Clutch on compressor seized and started to smoke.
3. Bought a new compressor, accumulator, orifice tube.
4. Replaced compressor & accumulator. Topped up oil in compressor to 11 oz, put everything back together.
5. Topped up with 2 cans of freon, about 1.3 lbs. It needs 2lbs.
6. When ac is on, comp clutch engages and disengages continuously, no cool air
what's wrong exactly?

Sounds like an improper charge. Did you use gauges? If not, I would check it that way first. I had the same issue with the clutch on a new compressor. Probably should check the orifice tube. A new one can accumulate whats it there pretty quick. I have heard that cleaning your old orifice and then reusing it with the new compressor for 15 min or so and then put the new orifice in helps in keeping the system clean.. Sandy

I bet you didn't remove "air" from the system. No matter the vehicle, you have to replace your parts AND THEN use a REAL A/C machine to vacuum air out of the system. If you don't know someone who has one go to a shop that does A/C repair, they can vacuum air out and leak check it before you fill it. This is the most effective way to make sure you don't have air mixed with your refrigerant. Replacing parts is easy, however there is a science to making these systems work correctly, sounds like you skipped a crucial step.

You might want to take it to an A/C shop and have them evacuate the system and re-fill. From what it sounds like, I'd bet the system was overcharged. The A/C shop shouldn't charge more than 100~125 for this. It's much cheaper than replacing parts-trust me, having learned this the hard way, I know!
