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.

Corbett Lunsford

For our family's performance-tuned home, I’m giving you a deep-dive into the beginning stage of the heating/cooling and ventilation ducting throughout the house. See assembly, fastening, sealing with mastic (the good stuff, not the cheap stuff) for duct boot stacks and outdoor vent hood terminations.
