EP285 You Can't Control a System That's Open - Ken Allison on HVAC and the Building Envelope (August 2026)

Quotes from the episode:    "I don't need the house to breathe. I need the people to."    "You can't control a system that's open."    "I would just go make them comfortable. And let them know the added benefit is that they're going to spend less on energy."    What happens when an HVAC contractor fixes the equipment, but the customer still isn't comfortable?    In this episode of Building HVAC Science, Bill Spohn talks with Ken Allsion of Insulation Distributors (IDI) about why HVAC contractors are uniquely positioned to recognize—and potentially solve - problems with the building envelope. Ken argues that comfort complaints often blamed on heating and cooling equipment actually begin with uncontrolled air leakage, poorly installed insulation, and mechanical systems operating outside the thermal envelope.  <span class= "EOP Selected SCXW143917804 BCX0" data-ccp-props= "{
