Yes, but not nearly so well.

The CO2 or freon in a tin of "canned air" is a liquid and when the pressure is released it boils. To do so it takes heat from the surroundings and gets very cold.

 

For air the effect of expanding is much smaller. (And for a few gases like helium and hydrogen, they actually get hotter when you let the compressed gas escape).

probably tells you more about that than you want to know.
