Company profile
researched Aug 2026Quilt develops and sells a ductless heat pump system for residential heating and cooling. The product is presented as a single system composed of four parts: an indoor unit, an outdoor unit, a wall-mountable or tabletop control dial that functions as a thermostat, and a mobile app. The indoor unit stands 7 7/8 inches tall, includes occupancy detection to reduce energy use in empty rooms, and receives over-the-air software updates. The outdoor unit anchors the system and is designed for quiet operation in exterior spaces.
The system is all-electric and marketed on efficiency and granular control: homeowners can set temperatures room by room from anywhere in the home or remotely via the app, which also provides scheduling and hourly, room-level energy usage insights. An "Auto-Away" feature uses occupancy sensing to reduce energy consumption in unoccupied rooms. The company states a SEER2 rating above 25 and describes the product as the most efficient two- and three-zone system available. Additional stated features include remote diagnostics and a warranty of up to 12 years available through partners.
Business model
Quilt sells heat pump hardware and an accompanying software/app experience for residential use, with installation delivered through a certified third-party partner network rather than in-house crews.
