Question about Recirculate button.

[louiellopez]

The only times I don't use recirculate are:
1. When someone farts
2. When we are in an open area free from pollution
3. When a balikbayan insists to turn it off to get "fresh air" despite me saying "Oh, it's not fresh."

I noticed the a/c gets a little warmer with recirculate off.

Thank you Sir naliwanagan na po ako.
