QUOTES from the Episode

"Instead of landlines everywhere, give every heat pump a cell phone and let it call home."

"We're seeing close to 40% of heat pumps undercharged or leaking—no wonder callbacks are high."

"What gets measured gets managed." — often attributed to Peter Drucker (fitting this data-driven shift)

Brendan Hermalyn (CEO/founder, Thalo Labs) traces a zig-zag path from NASA and defense to self-driving cars—then into HVAC. His through-line: high-reliability sensing and prognostics. Thalo's product aims to "give every heat pump a cell phone," using a small, non-invasive module that snaps inside VRFs/splits (and eventually larger plants), measures power and line temps, backhauls via cellular, and flags undercharge/leaks and power-quality issues before they become emergency calls. It's equipment management, not a full BMS—lightweight to install, built for techs, and friendly to API integrations, texts, and weekly roll-ups.

Brendan argues the market is ready: most commercial buildings still lack BMS, Wi-Fi is fragile for critical telemetry, and the economics of sensors/cloud have flipped. Thalo avoids tapping the refrigerant loop, prioritizes fast installs (often 10–30 minutes), QR/location tagging, and even a "buzz this unit" feature to find the right rooftop box. Early field data is sobering—he's seeing ~40% of heat pumps undercharged and/or leaking—driving callbacks, compressor failures, and energy waste. The pitch to contractors: turn break-fix chaos into planned maintenance, white-label the savings report, and train new techs faster with data-driven cues. Oh, and the name? "Thalo" like the deep sky blue—an homage to adding tech to make the picture clearer.
