How the Best HVAC Equipment Gets Made: Fast Tour of Mitsubishi Cooling & Heating Headquarters

Corbett Lunsford

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.

Ultimate HVAC Install and Testing: High Performance Heat Pump and Ductless Mini-Split

Corbett Lunsford

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!

Testing the Air Handler Cabinet Leakage

Corbett Lunsford

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.

Cleaning Ductless Mini-Splits

Corbett Lunsford

Home Diagnosis co-host Corbett Lunsford found out that his HVAC maintenance schedule was not adequate. In the highest performance tiny house on wheels in the world, the air quality goes downhill fast if you don't service the equipment. This is not a bash on mini-splits, it's a bash on how busy our lives get, and how many of us forget to maintain the machines that make our lives comfortable.
