Brief

Merino Mono heat pump is a wall-mounted, indoor-only unit that claims no outdoor condenser; it retails for $3,800 including installation and exchanges heat with outdoors through two small wall holes. Availability is initially limited to San Francisco and Los Angeles, and the founding team includes alumni from Quilt and Gradient (tweet posted Apr 6, 2026).
