Obviously your Cold air intake next to the furnace may draw a bit more air than it does naturally with the furnace off, but as no combustion is happening in the furnace with the AC on, I just can't see how running the AC the past few days would cause a significant increase in smoke ingress into the house....

Sorry, I've never had an a/c for my home so I don't know but doesn't it have to draw air from the outside?
Drawing air from another part of the house would defeat the whole purpose, that area would be super hot.
It's the second law of thermodynamics.
