Get a set of gages. Really. They are $70-80, and if you look for used ones you can get them cheaper. Make yourself more useful to your friends by being able to test their AC. They'll help you move that new fridge or keg-o-rator in :-) Check it out vs the shop manual specs. (See the SD tech folder for links to the manuals online). Then you'll know if it is in the AC system, or elsewhere. Never turn down a good opportunity to get a new tool...
It may also be a vacuum leak in/to the actuators that is the issue as RudyF6 noted. When it goes bad - what does it do? Does it go warm, or does the air go to a different vent position like the deforster or floor. If it goes warm, then it is likely the blend door. If the air goes somewhere else then it is one of the other actuators under the dash. Do you have the EATC or the manual AC?

well I am no A/C pro but I had a bronco that each time I steped on the gas to the redline the A/c would cut off and when I got off the gas it would get cold agin one time it went off and didnt come back on I looked at everything got out the hains book and checked the system drawings and found the (over pressure switch) tapped it with a wrench and suddnly I got my A/C back. not saying this was your prob just my prob.

Sigh...You're making this harder than you need to...
Grab a feeler gauge set. With the engine off, crawl under the truck and measure the clutch air gap.
If over .035", the gap is excessive. Either remove a shim if one is still in there or replace the hub.
If you do remove a shim, store it so you can find it back again later.

Y'all, you can find a climate control troubleshooting manual at Tech Support, Manuals & Troubleshooting for Consumers search for "412-00-7 2007 F Series Climate Control Manual". I posted it today, should be there tomorrow.

This is not exactly on-topic, but you know, a big part of the problem here is Shade doesn't know a mechanic he can trust. I know a few (VERY few) mechanics I could go to with an A/C problem, and they'd hook up the gages and check it out for me, without giving me a whole shuck and jive about it.
Maybe my situation IS an exception: a close friend of mine was a Toyota Factory Trained mechanic for many years. We were pretty close: before he passed away he left me all of his tools, on one condition: buy new toolboxes for them, 'cause his were total carp. Even before he died, I had become dear friends with one his old buddies. His place is not far from my office: sometimes if I'm leaving work early I'll drop by his place with a few cold ones and just shoot the shtuff.
Now, he can't (or won't) do everything, e.g. new ABS brake systems or transmission rebuilding, but everybody he has sent me to for those things has been top-notch, both professionally and personally. I just spent a small fortune having an 'auto-electric' place fix my alarm installation screw-up, and y'know, they were classy folks: they didn't even yell at me for being a moron who should leave stuff to the professionals, which is what I've come to expect from most mechanics.
The point of my rant is, why are there not more auto-repair folks like that? While my friend points me toward the good guys, he also knows all about the local bad guys too. And there's a lot of them. Jerks at best, crooks at worst.
It's a sorry state of affairs when a guy can't find a decent mechanic who'll spend fifteen minutes (PAID!) to take a look.
