Everyone blames the HVAC System. Most of the time, that’s wrong. Nikki Krueger breaks down why modern homes struggle with humidity, even with high-efficiency systems, and why dehumidification has become a missing piece in comfort, health, and durability.

Sam, Ben and Nikki talk crawl spaces, shoulder seasons, overcooling, air leakage, ventilation mistakes, and the real-world install details contractors keep getting wrong.

If you work on houses, or live in one ... this conversation will change how you think about moisture control.

On this episode of Flow Lab, Ben Walker and Sam Myers sit down with Leilani Orr and Ty Branaman from the Grit Foundation to talk about a very practical way to grow the trades pipeline: youth camps where kids actually do the work.

Instead of PowerPoints and lectures, these camps drop 12–17-year-olds into escape-room-style challenges with real tools, real wiring, and real jobsite scenarios. Mentors don’t just “show and tell," they use a Socratic, question-first approach so kids learn to think, measure, troubleshoot, and fix things for themselves.

You’ll hear how the camps are structured, what it realistically takes to host one, and why mentors come away just as energized as the students. From high-school interns in Retrotec’s engineering department to kids proudly taking home their own wired “wall boxes,” this episode is a how-to guide for turning “we need more people in the trades” into real action in your own community.

In this episode, we get into:
- How the Grit Foundation youth camps introduce 12–17-year-olds to the trades using real tools, real circuits, and jobsite-style scenarios
- Why curiosity, questions, and mistakes are built into their Socratic teaching approach
- The mentor’s role, the 1:2 mentor-to-student ratio, and how a detailed playbook keeps camp days on track
- What it actually takes to host a camp: facilities, background checks, safety, and community partners
- How these camps help kids connect the dots between fix-it life skills and real career paths
- Why building science and HVAC are directly tied to public health and safety, not just comfort
- How programs like this can help your local market build its own long-term talent pipeline

If you’ve ever said, “We need more people who actually understand how buildings work,” this episode shows one concrete way to start building that future, right where you live.
