 That's the air that's coming in to replace what's venting out. And so it keeps that area cold. So this is a great solution for that. If you had a trick or tip like this for the show, I'd love to hear it. Head over to Around the House online. Send me a message over there. And we've got a message system where you can drop me a note. Around the House will be right back after these important messages. Don't go anywhere. We come back. We'll talk more about their details of how that works. We'll do that just as soon as Around the House returns. Don't go anywhere. We're just getting started.
