air conditioner blows warm air at idle. on 2006 Ford Freestyle

Air conditioner does not put out cold air at idle. works good, not excellent at higher rpm. Had ford dealer look at it they say it's ok. At idle in hot 90+ days only puts out warm to cool air.

Use the circulate air icon button. It looks like a car with an arrow around it. It will cool inside air quickly.
