Talking Points

Recent interactions between the hosts and their guests.

EP268 Fresh Air Without the Penalty: Reinventing Ventilation for Real Homes With Austin Riesenberger from Swerv (April 2026)
Q: Devil's advocate: why not just open a window instead of a new device?
Opening a window can work but wastes energy and comfort, especially in extreme weather or polluted days; the device delivers fresh air with filtration and maintains indoor conditions.
EP268 Fresh Air Without the Penalty: Reinventing Ventilation for Real Homes With Austin Riesenberger from Swerv (April 2026)
Q: Excellent. So, I guess first describe the product, and then tell us about the motivations for the particular features you have.
The product is a window-mount fresh air machine that seals in nicely, brings in outside air while filtering and maintaining comfort, and avoids the energy waste and discomfort of open windows or bulky traditional ERVs.
EP265 Why Heat Pumps Fail: It's Not the Equipment, It's the House With Larry Waters and Alex Sloan (February 2026)
Q: Larry, would you come back to discuss the history of electrification in the United States?
Yes, Larry would love to do that, and they could easily fill an hour or more with the history and policy shifts shaping electrification.
EP262 "RTFM" and Real-World HVAC Confidence: Why Callbacks Drop When Training Improves With JT Stewart (February 2026)
Q: Where is your training available if listeners want to attend?
JT explains that Slipstream runs the Michigan Heat Pump Collaborative, with installer and comfort advisor trainings across Michigan, Minnesota, New England, and beyond through distributors and state programs, emphasizing frequent sessions and growing coverage.
EP261 From Journeyman to Trainer: What Actually Works and Why With Don Gillis (February 2026)
Q: What was the turning point that pushed you toward becoming an educator and trainer rather than staying strictly in service?
The turning point was recognizing that teaching others, sharing experiences, and building durable skills could have a bigger, longer-lasting impact than climbing the next corporate rung, especially after seeing how much people learn when you invest in their growth.
