How to Hide HVAC Grilles and Replace Your A/C Faster

Corbett Lunsford

My friends, DO NOT DO THIS. Friends don't let friends put HVAC grilles, especially the central return grille, anywhere a couch might end up backing up against it. Ceilings, great. High wall, fine. Floor, not so great but probably better than this. Learn more about HVAC performance by subscribing to our channel and joining our Patreon membership: https://Patreon.com/HomeDiagnosisTV

Here's a brain dump on how to look up the performance data on products like this.

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
