I thought I was alone on the quest to research and teach folks about duct and system leakage. Turns out I’m not alone. Meet Mark Mahon, Business Development Manager for Price Industries and all-around great guy. (Nerdiness never prevented likeability, did it?) A...
I know you guys love my pop quizzes. In your duct system, what leaks most? AHU/RTU High pressure ductwork Low pressure ductwork Terminal box Life safety damper Access Door Diffusers Of course, the devil is in the details. Question is, how much of this information is...

I’m stretching the hell out of this analogy, but let’s go with it. A ceiling opening is the nail, and just about all of you have settled on a plaque diffuser as your hammer. And for good reason. A great performing product, fairly priced, plenty of competition. But...
I’ve said it before. Mixing ventilation is like a bath. Displacement ventilation is like an upside-down shower. I wrote about it 10 years ago. Wow, time flies. Here’s a link to the archived article if you’re curious. We even made a fun little explainer video on the...
