Testing Custom HVAC Grilles with a Blower Door
Corbett Lunsford
Watch home performance testing guru Corbett Lunsford test the pressure, airflow, and velocity performance of some beautiful custom carved wooden return grilles, using just a blower door kit, a homemade box, and an anemometer. Grilles made by Stellar Engraving by Vencor Inc. (http://vencorinc.com). Test performed out of the back of Corbett's pickup truck in Atlanta GA! Yeehaw!
