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 the Air Handler Cabinet Leakage

Mastermind student Treondras and I isolated the air leakage built into my Mitsubishi heat pump’s air handler cabinet using a Retrotec Duc Tester 300 and DM-32 gauge. Turns out I made the right decision with Mitsubishi! Their 5 cfm at 25 Pa beats Neil Comparetto’s 6 cfm record. Good job guys.

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.

Testing Custom HVAC Grilles with a Blower Door

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!
