Quilt is building the modern home energy system, starting with HVAC. It is the largest energy load in the house and the system people touch every day. Quilt's first product, a ductless heat pump, is the smartest way to heat and cool your home. With industry-leading SEER2 and HSPF2 ratings it is 20% more efficient than comparable ductless heat pumps, and it pairs that performance with sleek, architectural design, intuitive room-by-room control, real-time energy usage tracking, and radar-based occupancy detection.
Quilt is a software-defined system: every unit is connected, instrumented, and updatable over the air, so performance improves after installation rather than degrading. That architecture is protected by a portfolio of issued and pending patents spanning hardware design, software control, and distributed system architecture. Quilt's Certified Partner network, built from zero starting in 2025, now spans more than 150 partners across 46 U.S. states and Canadian provinces, a channel built to compound and to carry every future Quilt product to market. Monthly installs grew over 5x in the first half of 2026, and the company maintains a customer satisfaction score of 4.7 out of 5.
