Recent interactions between the hosts and their guests.

EP279 Curiosity, Heat Pumps, and the Details That Matter – A Conversation with Edward Louie (July 2026)
Q: What would you like to leave listeners with as a closing thought about the wide range of topics you're interested in?
Stay curious about your built environment, pay attention to your energy bills and systems, and keep learning by asking questions; the habit of curiosity drives improvements in comfort and efficiency.
EP279 Curiosity, Heat Pumps, and the Details That Matter – A Conversation with Edward Louie (July 2026)
Q: If you had a choice to buy equipment today, what would you install in your own home?
An inverter-driven heat pump with good modulation and right-sizing, focusing on modulation performance over extreme cold-start specs; data from the NEEP database informs the thinking but overrated minimum modulation can be avoided by proper sizing.
EP279 Curiosity, Heat Pumps, and the Details That Matter – A Conversation with Edward Louie (July 2026)
Q: Is there anything contractors should know that manufacturers aren't emphasizing enough?
The importance of airflow and the ability to adjust fan speed and static pressure; many manuals hide this in hard-to-find settings, leading to suboptimal installations and performance.
EP279 Curiosity, Heat Pumps, and the Details That Matter – A Conversation with Edward Louie (July 2026)
Q: How about the heat pumps? What is your current message about modern heat pumps and how much they've changed over time?
Edward explains that modern heat pumps perform well in cold conditions and are efficient when properly installed; the key takeaway is avoiding over-sizing and ensuring correct airflow and system sizing for real-world comfort.
EP277 Dirty Little Secret: Why Heat Pumps Need Deep Cleaning with Gabriel Erde-Cohen (June 2026)
Q: Question for you, what actually do you clean when you clean a heat pump?
We start by safely powering down, then remove the interior head, protect surfaces, and use a low-pressure wash with an alkaline soap, finishing with an enzyme spray to reduce residual biological activity; everything is contained and removed in a way that avoids water damage and ensures the condensate line carries debris away from the building.
