HVAC Airflow Diagnostics: Testing Carved Grilles for CFM, Velocity, Pressure Drop, and K-Factor

Corbett Lunsford

Our longtime friend and Patreon supporter Scott Marner (who manages QA for Illinois' Ameren home performance program) joined me to do some off-label, outside-the-box diagnostics on custom decorative HVAC grilles from Stellar Air Vents (https://stellarairdecorativeventcovers.com/). Just one more example of some non-engineers getting very sophisticated results from a cardboard box, some tape, and several thousand dollars of Retrotec and Testo HVAC testing equipment (https://www.trutechtools.com/). Scott was our FIRST EVER Patreon supporter- join him and become part of our work on this channel and the 'Home Diagnosis' TV series: http://Patreon.com/HomeDiagnosisTV

Testing the World's Worst Duct System

Corbett Lunsford

I'd love to show you this, but my client has asked that I take this video down while they try to reconcile with the installer. Fingers crossed everybody, and sorry to be a tease.

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!

Mystery #1: Solve the Air Conditioner Problem!

Corbett Lunsford

Welcome to the new series where you solve it yourself! Watch me demonstrate a common problem happening in a brand new home- will you be able to diagnose the problem and prescribe the solution?  In heating and cooling, airflows and pressures are the most critical and least understood factors for performance.
