Thanks for all response.

sorry for not being clear. when i turn the A/C on and recirculating off, it blows cold air. When I turn the A/C on and recirculating on, it feels the same as A/C on recirculating off. no significant gaining on air flow and coldness.

My last refill was last year.

just I remember all the cars that I driven before, when I have A/C ON and recirculating ON, it always seem cooler and more air flow, And no odor from outside.
