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

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

Ventilation, Diagnostics, and DET Verifier Training Break Down

Done with our first 4-day training at our Atlanta home- save a spot in the next one! This time we had people travel all the way from New York and Texas- remember, we’re 5 minutes from the busiest airport in the world, and this is a state-of-the-art training center. You’ll be happy you made the time for the trip!

Testing Ducts During Construction

My Mastermind student Rashaun joins me to test my custom return filter box plenum with a Retrotec DU300. I used enough mastic to swim a camel, so we’ll see how tight my ductwork is. Sheet metal fabricated with Malco sheet metal tools.

Supply Ventilation for Homes: Mythbusting Side Effects

'Home Diagnosis' co-creator and building science trainer Corbett Lunsford has told many students that supply-only ventilation is dangerous for homes in cold climates- but is that scientifically proven? Watch performance testing that will demonstrate exactly what happens (or doesn't happen) when pressurizing a house with supply ventilation from outdoors.

Bubble Experiment with a Blower Door

To try and seal the last nasty little leaks in the Mento 3000 roof membrane, Corbett and his Dad try an experiment using soapy water and a flipped-around Retrotec blower door.

How to Teach Home Performance to Home Owners

See how Corbett teaches home performance to the uninitiated after having given this presentation 214 times across the U.S. on the Proof Is Possible Tour. Special thanks to the tool companies and all other sponsors of the upcoming TV series 'Home Diagnosis' who have invested in making home performance a mainstream topic:

Most Airtight Barn at an Off Grid Homestead Ever?

Corbett performs a blower door test on LG Squared Architecture's #OffGridHomestead. Will Chris's toolshed beat the record set by the #DryVault? Will Passive House standards be outperformed? Will Corbett remember to plug in all his hoses?

Proving the Airtightness and Insulation of the #TinyLab

Join building diagnostics guru Corbett Lunsford as he tests the airtightness and insulation of the #TinyLab, the highest performance tiny house on wheels in the world. Using a Retrotec 5000 blower door, DM-32 smart gauge, and ThermApp infrared camera, he proves that the #TinyLab is truly a work of science and art at the same time.
