4 Year Old Tests Home Air Leakage

My daughter can find out whether your house will perform well or not- but I got to be her first client. She runs our Retrotec 5000 up to 50Pa and shows off how awesomely airtight our family's forever home will be for the next 100 years.

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.

Super Airtight House: Blower Door Test

Corbett and Grace and their family have built a house that has better control over air leakage than 99.999% of any house ever built, anywhere in the universe. Here's how they found out.

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.

Static Pressure Testing Demonstration Galore!

Watch building forensics expert Corbett Lunsford demonstrate Total External Static Pressure testing and pressure drop testing for a residential furnace and air conditioner.  Learn to diagnose pressure problems in supply and return ductwork, filters, evaporator coils, and duct sections in just a few minutes with a minimum of testing tools!

Tiny House Blower Door Test: #TinyLab Test Series #1

Watch as Corbett and Grace test their airsealing work on the Tiny Lab with a Retrotec blower door! They fire up the new Model 5000 fan and find that the house has approximately 160 CFM@50 of air leakage, which is 4.7 ACH50 and 0.14 CFM per sq. ft. of enclosure surface area- and that's with stupid tarps over the window holes! We're going to test again when the windows are in.

Thanks to Julie Tolliver of Energy Fitness for Homes for the idea, to Retrotec for making awesome equipment, to 475 High Performance Building Supply for supplying America with awesome airsealing kits, and to Hewlett-Packard for creating awesome video editing stations that we work on every day.

Field Check a Flow Hood Using a Duct Leakage Test Fan

Learn to quickly and easily check the accuracy of a flow hood (in this case, a TSI AccuBalance) using a duct tightness testing fan (in this case, a Retrotec DucTester 200). If your diagnostic equipment isn't giving you accurate readings, no amount of experience will save you!
