So this year the air in my F 150 was not working too good. Since it gets a little warm out here I thought I had better get it recharged. The closest place to me ( Firestone ) wanted 140.00 to do the job. I decided to see what the auto parts store had and bought an item called A/C Pro. I wanted to let you guys know that this stuff is great ! It took me all of 20 minutes and the air was so cold I had to put it on it's lowest setting. If your air is not working as good as it has in the past give this stuff a try. I paid 40 bucks for it at Auto Zone.
