Even if you're not a market refrigeration tech, we all know that the primary function of refrigeration is to keep food cool. Easy, right? Even though food storage sounds pretty simple, there are a lot of things we should keep in mind when we think about food safety and quality. There’s a lot more to […]

That combo can cause all sorts of problems: […]

In this live recording from the AHR Expo, Kaleb Saleeby, Nate Adams, Michael Housh, and Steve Rogers discuss building performance. The building science world is an exciting place; we're all excited about improvements to reheat dehumidification, which is when we use waste heat to take care of humidity without cooling. As equipment becomes more efficient, […]

In this episode, Nate Adams and Michael Housh give the HVAC 2.0 rebuttal to the idea of standard load calculations. They take a different, possibly more radical approach to proper sizing. Michael and Nate believe in doing real-world load calculations, not just relying on models for load calculations. They are on the side of replacing […]
