Does your return air grille whistle- Do this to fix it and increase airflow


If you have one of the return air grilles pictured below in your ceiling or wall, listen up.  The fins are angled to hide those ugly filters we put there to keep our coil and air clean.  The downside to the bend in the grille is a reduction in airflow and sometimes a nasty whistle.  Do yourself a favor, go out to a big box store and get a sheetmetal hand seamer tool (or borrow from someone).  Straighten out those grill vents and you will increase your airflow 20% RIGHT NOW.  Don't worry the grille will not break just take the seamers and straighten them out in one motion.  Check out http://www.thermal-medics.com/ for more great DIY and helpful advice.  You can call or email for free your questions, problems or concerns.
