Seal Return

Today we are correcting a problem that you might be able to hear. Everything in here looks fine but if you hear this return is making a pulsing noise I'm fixing to show you why. My return is not sealed and it's sucking in attic air from elsewhere so my job today is to seal the return. All right job's done. Let's just say that was more difficult than what it looked like. I felt like I was in a mud wrestling match on the floor and if you listen carefully the pulsing at least 95% of it is gone so that's what a sealed return will do for you.
