2011 F250 6.7 Air Conditioning Issues

Having problems with me 2011 (26,00 miles) with the air conditioning. Got progesssivley worse and took it back to the dealer, They replaced the compressor as they said it was leaking at the halves. Picked it up and it never really cooled like new so I took it back. Again, they said the new compressor was leaking and replaced it. Still not cooling as far as I'm concerned and haven't taken it back from the dealer and they're supposed to be working on it. When I put a thermometer in the AC vent at best it cools 80 degrees when set on recirc and 60 degrees. Dodge Ram rental truck cools at 60 and gets cooler when moving. My 09 Platinum runs in the mid 50's as well as 07 Corvette. Delear scratching there head and saying it's working.

Anybody have what the Ford spec is for outlet air temperature? This can't be right cause it doesn't cool worth a dang.

I don't know the spec but in my truck you seriously need a coat on inside with the aircon set to the lowest temp even if it's 80 degrees outside. You need a dealer that knows what they are doing. You might want to go to a shop that specializes in air conditioning and just ask them to diagnose your system so you can get the dealer to repair it since it's under warranty still. It'll probably cost you a couple hours labour but maybe the dealer will reimburse you for some of it since they obviously had no clue.

Sounds like a dealer issue. Your should definatly see temps in the 40's if its 80 outside.

Working Phoenix (99-123 degrees), truck runs all day..ac is fine. Seems like the dealer has maxed his skill set..!! I agree with an ac diagnosis by a ac tech.....

mine was getting where is was only blowing in the hi 40s to very high 50s coming from the vents. It was struggling on 90+ days. I borrowed a friends gauges and reclaimer. Emptyed the system out. bleed 50/50 new with old 124a and all is well now. The gauges showed the Freon was in spec. FYI truck had 90k on it then now has 93.5k all is good.

Anybody turn on the ac and get nothing but high heat? I have to shut the truck off, restart it and then the a/c will work.

8000, yes I had that long time ago. the bleed air door gets confused. a reboot usually fixes it. mine did it 2 times in a row after a battery change so I did a relearn to the module by pulling a fuse under the kick panel. turning truck on and do fan from hi to low to hi to low then cold to hot to cold to hot and reinstall fuse. fixed ever since. Same thing happened to my 2011 250 work truck after new battery.

Thoughts on the original poster's issue. Most newer a/c systems have an evaporator temp sensor that reads the temp in the evaporator. If it is reading incorrectly it won't run the compressor the correct amount of time. Also cab air filter dirty. Drain lines plugged up and not dripping freezing up the evaporator. Is the condenser plugged up with bugs and debris? These would be the most common things I look at when I get a complaint of a/c not cooling well. Granted I work on tractors but from what I've seen pickups are real similar in design of the systems.
