have you calibrated it in a glass of ice water?

I found a digital thermometer and it reads 5 degrees cooler than the analog one from aap. I guess then my system is within specs, but I still feel like it could be colder. The true test will be when the Texas summer heat returns.

FYI
My 04 is ice cold not long after start up. I can easily run my fan on 4 and still feel ice cold air coming out. Unless they changed something, I'd say you still have an issue.

He has an issue, a system just does not loose 32 ounces of freon. As I said earlier, I think a previous owner stuck a sealer in it and its clogged up, especially the fixed orifice valve.

No, it's not PNP, it requires some modification to fasten the 2010-F150 electric fan onto the radiator, and then you needed an electric fan controller to control how the fan will turn on and off at a certain cooling set points.
Yours probably has inadequate refrigerant and or issue with blender door or bad condenser dryer etc..

Same as mine. Our A/C systems do a good job of cooling the truck. I live in the "Africa Hot" summers of Florida. My A/C cools great as Summers22 reports his does.
Freon does not get "old" or "stale" as some of the posts here have lead the OP to think. Sure, our trucks are older, but the A/C system will work just fine as long as there are no leaks, the A/C system holds pressure, and good air flow is happening through the front of the trucks A/C condenser. Folks who install light bars in front of their grills, or other objects that block or lower the air flow in the front are not helping. Fittings or other A/C hoses will deteriorate over time, so these are suspect places to look for leaks.
A good electric fan will help. This is one of the reasons why Ford (and other manufacturers) have now gone the way of electric fans over clutch type fan setups.

I would trade my electric fan in a heartbeat, for an old on engine mechanical one! The at idle and at first is normal, until the higher RPMs kick in. He has a leak or a bad component. He should be getting at least, on the poor side for that year, 39-40 degree vent temp. My 08 after replacing the Fixed Orifice valve hit a steady 40, with 130K on it.

This brings about a new issue though. If his system requires 34 oz and he only put in 32 oz, then he is still low. He needs to talk to the shop and determine what actually transpired in this fix. Just a top up, which should not happen, or an evacuation and refill. If the latter, then why on 32 oz?
