Can anyone help with me with my AC?

And, the refrigerants are compatible (confirmed by a couple of A/C shops), but I did a complete replacement rather than blending refigerants.

WTF is 12a refrigerant? all i do all day is repair a/c recovery machines. i have never heard of 12a refrigerant. i would defiantly not put some other type of refrigerant in your car.
did you discharge that A/C Pro garbage into your vehicle? i hope not because that stuff is total junk! never use any products that contain any type of stop leak. you will most likely need to replace every component in the system if you use this stuff.
also, if this "12a" uses less weight to achieve pressure it would have an adverse effect on low pressure switch and expansion valve causing a lubrication issue resulting in system damage.
but, a manifold gauge set is key to diagnosing issues in A/C system...
