One thing I know about engineers. They love pop quizzes. Here’s some food for thought before our Air Distribution (AD) class on 03/03/26. Here’s a plaque diffuser. It’s a terrific general-purpose diffuser. 1. Here’s a directional diffuser. Does it perform any...

The video depicts a common phenomenon. Last I checked: Hot air still rises Engineers still prefer VAV systems VAVs in heating mode still limit air flow from 30-50% Is it really so shocking that typical diffusers don’t make spaces comfortable in heating mode? When’s...

Who doesn’t love a good conspiracy theory? Hear me out. Think about all the companies that you ever purchased or specified grilles and diffusers from. And think about where they came from. Titus? That’s Texas. Krueger? Funny, Texas again. Nailor? Guess What? Texas....

When you pick a ceiling or sidewall diffuser, the throw in heating and cooling mode changes due to buoyancy. You have to pull out the book, look at the flow, and look at the throw, to get the right neck size. Get that wrong, a draft is created, as is a call back for...

I think a solid gold thermostat would be amazing bling for these guys. After all, they are storytellers. Wouldn’t it be cool if we all could take our thermostats with us? Temp control wherever we go. DJ Khaled probably runs a bit hot, being a big guy. Snoop, on...
