How Cold is your AC?
My AC is not very cold. Its been this way since I first drove it. I would say it blowing air in low sixties High fifties out side temp is in the 90. It does not seem to cool down the cab down.
I also notice that when turn of the AC it blows hot air.
Thank you.

Not sure what year your truck is
But since you posted in the 6.7 area I will assume it is under warranty
Take it to your Ford dealer service department and the will check the temp coming out of the vents and if needed will fix it
It might need a recharge and that is a simple fix
Good luck .....

I have the manual controls and if I only use A/C and recycle air, it's not all that cold.
But there's a max A/C button (forces recycle) and it will freeze me out.
Never have I had a vehicle with air this cold.
If that's not the case, take it in as the others said.

I began noticing the AC getting worse before it failed. Just wasn't getting cold enough. Ford had a quality issue with the supplier of these coils. My build date was December 2010 (second job truck) of the 2011 model. Let us know what you find out. Good luck. If the coil is failing, it is a lengthy job. The entire dash needs to come out.

cold air
Yeah I ran my for 2 hours today on MAX AC and It never got cold. It is like the system starts off cold and then starts blowing warmer air when the engine heats up.
I will take it it tuesday. I don't want the NOX update so I have been avoiding the dealer. I will leave a note on the dash and duck tape ODBC connector.

I need to get mine in for a chronic problem I have with the 4 to 5 shifting. I know there was at least one new TSB for the NOx sensor. Are there problems with it?

For $40 you can go to oreilly (or wherever) and get a 134a charge bottle with a pressure gauge and give your a/c a charge. The pressure gauge reads the psi on the low pressure side. If the ambient temp is 90, the system should be around 55psi if I remember right. This is with the compressor running.
I have topped off the systems in two super duty trucks, expedition, and an f150. They all were low from the factory.
I've never been able to get 40° air though. That's pretty cold, you're lucky.
With the way the new blend doors work and the ability to turn a dial and specify that you want 72° air, you may want to be sure that those are working correctly. Especially if as you describe, the air is colder at first. When the engine coolant warms up you may be heating up the heater core and blending hot air with your a/c without knowing it.

I have to put mine on max air to get it to cool quickly....
all 3 of my excursions I left it on auto except on the most extreme days here in TexUS
I brought mine in and of course they said it was fine... going to another dealer next time...
