We're back again with my HVAC design calculations trainer Alex Meaney (https://MeanHVAC.com), to talk about ductwork and connections and filters and how to get all this right when replacing an old system in existing homes.

I've always wanted to go, and am finally learning some new tips and tricks that Mitsubishi puts into their high performance equipment to be a little more ballsy than other manufacturers. See a slice of the innovations in ducted heat pumps, ductless minisplits, testing at extreme environmental conditions, an 11-acre warehouse, a tech support division staffed by HVAC contractors with working demo units and controls, and more. Thanks also to Ryan Burrell who led the technical discussion (and who helped me select the exact Mitsubishi heat pumps that went into our new home).
Thanks to Matt Hoots (https://youtube.com/c/SawhorseDesignBuild) for putting together this trip to Mitsubishi's HQ in Atlanta GA.

Boy, were we lucky to have these two people help us get our heating and cooling engines running: Kaleb Saleeby from Kalos Services (https://www.kalosflorida.com/) and the HVAC School Podcast, and Brent Ridley from H&M Services in Atlanta (https://handmservicesinc.com/) and the Tool Pros Podcast. These Applied Scientists in HVAC take our Mitsubishi Electric heat pumps (one ductless mini-split, one ducted air handler) from unboxing to perfect performance, using the latest tools and techniques. And thanks to everyone else who helped us with guidance along the way!

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.
Now that the Mitsubishi heat pumps, Ultra-Aire dehumidifiers, and Fantech ventilation systems are onsite, Corbett gives a sneak peek at how they all fit together with the upcoming Fanimation fans and Kichler low-heat lighting to tune the indoor environment.

Grace and Corbett built the world's highest performance tiny house on wheels in 2016. It was perfect. Then they toured it 13,000 miles across America and let 7,000 people come inside to feel, hear, and smell what perfectly tuned home performance is like.
What's the house performing like now, after all that torture? And under 2 inches of snow in Atlanta, Georgia? See for yourself in this 20-minute tour, complete with testing, demonstrations, and metrics that show Proof Is Possible, even for people who have never built a house before. The #TinyLab is still the undisputed most scientifically superior home performance demonstration in the world, and we sincerely hope others start challenging our work!
Corbett likes tools that are sexy and scary at the same time. This flow hood is both. Measure CFM, Drybulb, Wetbulb, Dewpoint, Velocity, and more with this very affordable tool that will help revolutionize the HVAC industry.
Today I talked with Bryan Orr of the HVAC School Podcast about why home performance is the future of all residential construction and home improvement.
Building Performance Workshop's Corbett Lunsford, with expert help from Uplifting Air's Brad Lemley, installs and commissions a 1/2 ton Mitsubishi ductless mini-split heat pump on the #TinyLab tiny house on wheels for the Proof Is Possible Tour.

Dear Corbett:
I thought I would send this your way. I live in the Central Valley of California. Yesterday it reached 106 degrees. I did an experiment with my house. My 1,883 sq./ft. house had a deep energy upgrade over three years ago. The heating and cooling unit is a 2 stage/2 ton heat pump with no back-up heat. The second stage of cooling is disconnected so I am cooling with 1.4 tons. That is one ton for every 1,345 sq./ft.
Yesterday morning I left the house at 7:40 am. It was 75 degrees in the house and 75 degrees outside. I closed all of the blinds, turned the HRV off and turned the Heat Pump off. In other words, I let the house float. It got up to 106 degrees in Stockton yesterday. Luci my bride got home at 5:40 in the afternoon and the house was 78 degrees. She turned the thermostat back on and it brought the temp back to 75 in 30 minutes.
This stuff really works.
Keep up the GREAT work;
Dick Rome
Dear Dick-
You are awesome. I'm not sure I know many other home performance experts who have fixed their own homes- most of our families have to suffer at home while we help other people get comfortable. Thanks so much for sharing the good word!
