EP271 Live from NHPC 2026: Where HVAC, Buildings, and People Intersect With Brynn Cooksey from HVAC-U PART 1 (April 2026)
Q: What role do testing and data play in convincing customers and in marketing?
Testing provides objective evidence of problems and solutions, which builds trust, supports pricing, and can be repurposed into marketing and case studies to attract new customers.
EP271 Live from NHPC 2026: Where HVAC, Buildings, and People Intersect With Brynn Cooksey from HVAC-U PART 1 (April 2026)
Q: How do you handle objections when the project is expensive or involves a large retrofit?
Objections are addressed by showing the consequences of not acting, presenting clear energy and comfort benefits, and using testing and financial framing to demonstrate ROI and reduce perceived risk.
EP271 Live from NHPC 2026: Where HVAC, Buildings, and People Intersect With Brynn Cooksey from HVAC-U PART 1 (April 2026)
Q: What is permanent load reduction, and why is it central to your approach?
Permanent load reduction involves reducing the building's heat loss and gain through insulation, air sealing, and shell improvements so that smaller, properly sized equipment can meet the load, improving efficiency and comfort.
EP271 Live from NHPC 2026: Where HVAC, Buildings, and People Intersect With Brynn Cooksey from HVAC-U PART 1 (April 2026)
Q: So Brynn, you moved from HVAC into shell work; was that a risky shift and how did you justify it to customers?
Brynn explained that it wasn't a risk so much as a strategic move toward bigger customer impact; the shell work reduces load and enables better, longer-lasting comfort, and once customers see the benefits via testing and energy data, they understand and buy in.
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.
