Just had my A/C vacuumed and recharged. Driver side is blowing cold, but passenger is not blowing cold. Could it possibly be blender doors? It should not loose Freon this fast and no notice of a leak I would think. Am I wrong?

Well turns out I had a bad valve stem on low pressure side and is now holding freon and staying cold longer than it did before. I may have another small leak else where. Can freon leak from high pressure side? Sure it can but thought I'd ask anyway.
