Some ACs (window units) will draw air from outside though.
Enviro Can & AB Health recommend no AC and no furnace fans since that will increase the amount of outside air drawn in through the fresh air line in the return venting.

Enviro can is right, but I figure it would be relatively minor amount of fresh air drawn with the AC running on a cycle basis through the day.
I have manual control of my HRV (cold air draw) so I simply turn off the HRV which further minimizes the amount of outside air being drawn through the cold air return.
With that said, if anyone in my house had significant reactions to the smoke outside, I'd not turn on my AC out of an abundance of caution... uckly my wife and kids don't, so I am cool!
