## Summary

Vince Romanin, CEO and co-founder of Gradient, explains how his company is building a user-installable window heat pump to decarbonize apartment buildings. He details the environmental impact of HVAC, specifically the harm of refrigerants and methane leaks, and argues that electrification is the primary solution. Romanin discusses the industrial design challenges of making a 90-pound unit safe for DIY installation and the supply chain difficulties of sourcing HVAC components as a startup. He also covers the strategic importance of variable-speed drives and connectivity for grid integration and future energy management.
